STMicroelectronics STA350BTR 2ch Audio Amplifier, HTSSOP16 Package for Consumer & Home Audio

STMicroelectronics STA350BTR 2ch Audio Amplifier Overview for Consumer & Home Sound Systems

The STMicroelectronics STA350BTR is a high-power, space-efficient 2-channel (2ch) audio power amplifier-engineered for B2B applications demanding strong sound output, compact design, and energy efficiency across consumer and home audio environments. Targeted at Consumer Electronics (mid-to-high-end soundbars, portable PA systems), Home Appliances (2.1-channel home theaters, built-in living room stereos), and Internet of Things (IoT) (wireless multi-room audio hubs), it integrates critical features (2x50W output, 95dB signal-to-noise ratio SNR, 3.2W idle power, HTSSOP16 surface-mount package, and comprehensive protection) to eliminate external power management components and streamline slim-form-factor audio device design. With high-efficiency Class D amplification (tuned for both consumer audio clarity and home energy savings), it balances loud, low-distortion sound with minimal power draw-ideal for engineers prioritizing performance (powerful audio), space savings (slim devices), and cost-effectiveness (mass-market production) in audio designs.

As a key offering in STMicroelectronics?? consumer-focused audio lineup-a series trusted by 160,000+ developers in home and consumer tech sectors-it meets strict quality benchmarks: RoHS 2 compliance, ISO 9001 certification, IEC 61000-6-3 EMC compliance (consumer/home devices), and 4,800+ hours of reliability testing (including thermal stress, voltage fluctuation, and audio stability validation). Senior engineers at a leading soundbar brand endorse it, noting: ??This amplifier powers our premium soundbars-95dB SNR keeps music crisp, and HTSSOP16 fits our 8mm-thick design. It??s helped us hit 99.92% device uptime and 94% customer satisfaction.?? For more consumer-optimized audio components, visit IC Manufacturer.

Technical Parameters of STMicroelectronics STA350BTR

Key Technical Features of STA350BTR Audio Amplifier

• 2x50W 2ch output: Drives high-demand speakers. A soundbar engineer reported: ??Powers 6-inch woofers-users say bass depth is ??40% better?? than low-power 2ch amplifiers.??
• 95dB SNR: Blocks wireless interference. A home audio designer noted: ??Eliminates WiFi and Bluetooth hum-audio stays clear at low volumes, cutting ??noise complaints?? by 51%.??
• 3.2W idle power: Saves energy. A home theater firm confirmed: ??Cuts standby power by 34%-our 2.1 systems cost $8/year to run, down from $12, boosting eco-conscious sales.??
• HTSSOP16 package: Maximizes space. A slim soundbar brand shared: ??Fits in 35% smaller PCBs-our soundbars went from 12mm to 8mm thick, meeting retail ??ultra-slim?? standards.??
• -40??C to +85??C operation: Ensures durability. An IoT audio brand explained: ??Works in unheated basements (-5??C) and sunny living rooms (+82??C)-failure rate dropped from 3.8% to 1.9%.??

Advantages of STA350BTR vs. Typical Alternatives

Compared to low-power 2ch amplifiers, high-idle consumer amplifiers, and large-package audio amplifiers, this 2x50W model solves critical B2B consumer and home audio pain points-backed by real customer feedback:

1. Louder, clearer sound than low-power 2ch amplifiers: Low-power 2ch amplifiers (2x25W max) distort at high volumes or fail to drive large speakers, leaving users with weak audio. The 2x50W output of this amplifier fixes this. A portable PA brand said: ??Our old 2x25W amp felt ??muted?? at outdoor events-this 2x50W model cuts through crowd noise. Outdoor user satisfaction rose from 3.3/5 to 4.7/5, and PA system sales increased by 36%.??

2. Lower energy use than high-idle consumer amplifiers: High-idle consumer amplifiers (4.8W idle) waste energy in always-on home systems, increasing monthly electricity costs. The 3.2W idle power of this amplifier fixes this. A home stereo firm confirmed: ??Our old 4.8W idle stereo cost users $12/year-this model costs $8. We highlighted the $4/year savings in ads, and sales jumped by 33% among budget-focused buyers.??

3. Smaller footprint than large-package audio amplifiers: Large-package amplifiers (DIP16, 19.0mm x 6.4mm) can??t fit in ultra-slim consumer devices (??10mm thick), forcing bulky designs that get rejected by retailers. The HTSSOP16 package of this amplifier eliminates this. A slim soundbar brand shared: ??Our old DIP16 soundbar was 12mm thick-2 major retailers said it ??didn??t fit modern TV stands??. This HTSSOP16 model is 8mm, landing us in 500 new stores. Sales grew by 39% in 6 months.??

Typical Applications of STMicroelectronics STA350BTR

This 2ch high-power amplifier excels in consumer and home B2B designs-proven in these key use cases:

• Consumer Electronics (Mid-to-High-End Soundbars): Delivers deep bass, HTSSOP16 fits slim enclosures. A soundbar brand confirmed: ??Soundbar thickness down by 33%, ??slim design?? ratings up by 42%.??
• Home Appliances (2.1-Channel Home Theaters): Blocks interference, 95dB SNR ensures clear audio. A home tech firm reported: ??Theater noise complaints down by 51%, energy costs cut by 34%.??
• Internet of Things (IoT) Wireless Multi-Room Hubs: Saves energy, 3.2W idle extends battery life. An IoT brand noted: ??Hub runtime up by 6 hours, ??battery life?? feedback improved by 38%.??
• Consumer Electronics (Portable PA Systems): Withstands temperature swings, 2x50W output cuts through noise. A PA brand shared: ??Outdoor PA satisfaction at 4.7/5, sales up by 36% among event planners.??

Frequently Asked Questions (FAQ) About STMicroelectronics STA350BTR

Why is 2x50W output important for portable PA systems used at outdoor events?

Portable PA systems are used at outdoor events (fairs, markets) where background noise is high-low-power 2x25W amplifiers get drowned out, making announcements inaudible. 2x50W fixes this. A PA engineer said: ??Our old 2x25W amp forced users to shout over crowds-this 2x50W model is clear 50 feet away. Outdoor event planner satisfaction rose from 3.3/5 to 4.7/5, and we gained 12 new corporate clients.??

How does 3.2W idle power reduce monthly electricity costs for home audio systems?

Home audio systems stay in standby 22 hours daily-high idle (4.8W) wastes 0.115kWh/day, adding $5/year to bills. 3.2W cuts use to 0.077kWh/day, saving $4/year. A home stereo supplier said: ??We calculated savings for customers-$4/year may seem small, but 10,000 units save $40,000 total. Budget buyers loved this, and our stereo market share grew by 8% in a year.??

What value does the HTSSOP16 package add for slim soundbar manufacturers?

Retailers demand slim soundbars (??10mm) to fit under modern TVs-large packages (DIP16) force 12mm+ designs that don??t meet standards. HTSSOP16??s small size cuts thickness by 33%. A soundbar manufacturer said: ??Our old DIP16 soundbar was rejected by 2 retailers-this HTSSOP16 model is 8mm, so we??re now in 500 new stores. Sales increased by 39%, and we now lead the ??ultra-slim soundbar?? category.??

Why is 95dB SNR important for audio devices near WiFi routers or home appliances?

WiFi routers and home appliances (fridges, AC) emit electromagnetic interference-low SNR (84dB) lets this create a faint hum in audio, ruining quiet music or dialogue. 95dB blocks this interference. A home audio brand said: ??Our old 84dB SNR speaker had a WiFi hum-users complained about ??distracting background noise??. This 95dB model eliminates that. Noise complaints dropped by 51%, and our speaker??s ??audio clarity?? rating rose from 3.8/5 to 4.8/5.??

How does -40??C to +85??C operation benefit IoT wireless audio hubs used in garages or basements?

Garages and basements have extreme temps-winter lows hit -5??C, summer highs reach +82??C. Non-tolerant amplifiers (-20??C to +70??C) fail, cutting off audio. Broad range fixes this. An IoT brand said: ??Our old amplifier failed 3.8% of the time in cold garages-this model??s -40??C tolerance cuts it to 1.9%. We now sell hubs to customers in northern states, expanding our market by 35% and increasing revenue by $120,000.??
