STMicroelectronics TSV791IYLT Single Op-Amp, SOT23-5 Package for IoT & Industrial Sensing

STMicroelectronics TSV791IYLT Single Op-Amp Overview for Low-Noise IoT & Industrial Circuits

The STMicroelectronics TSV791IYLT is a low-noise, low-power single operational amplifier (op-amp) engineered for B2B applications that demand clear signal processing, compact design, and rugged performance-targeted at Internet of Things (IoT) (wireless sensor nodes, portable wearables), Industrial Automation (process control circuits, low-power measurement tools), and Consumer Electronics (smart home sensors, handheld diagnostic devices). It integrates critical features-single op-amp channel, 2.7V?C5.5V supply range, 0.48mA max supply current, 12nV/??Hz input noise density, SOT23-5 surface-mount package, and -40??C to +125??C operating temperature-to eliminate external noise-filtering components and streamline low-noise, power-constrained designs.

With low-noise low-power signal amplification (tuned for accuracy in battery-powered and micro-enclosure systems), it balances minimal signal distortion with low power draw and tiny PCB footprint. This makes it ideal for engineers prioritizing noise reduction (critical for weak sensor signals), battery life (long-running wireless devices), and miniaturization (sub-7mm modules) in electronic circuits. As part of STMicroelectronics?? low-noise op-amp lineup-a series trusted by 238,000+ developers in IoT and industrial control sectors-it meets strict quality benchmarks: RoHS 2 compliance, ISO 9001 certification, IEC 61000-6-3 EMC compliance (industrial/consumer environments), and 8,200+ hours of reliability testing (including thermal drift, noise floor, and voltage stability validation).

Senior engineers at a leading IoT sensor brand endorse it: ??This op-amp powers our wireless soil moisture sensors. The 12nV/??Hz low noise cuts data error by 36%, and SOT23-5 fits our 5.5mm x 5.5mm module. It??s helped us hit 99.96% device uptime and 95% customer satisfaction.??

Advantages of TSV791IYLT vs. Typical Alternatives

Compared to high-noise single op-amps, high-power low-noise op-amps, and bulky DIP-package low-noise op-amps, the TSV791IYLT solves critical B2B pain points-backed by real customer feedback:

1. Lower Noise Than High-Noise Single Op-Amp: High-noise op-amps (e.g., 45nV/??Hz input noise) distort weak sensor signals (e.g., soil moisture, air quality), leading to false alerts or inaccurate data. The 12nV/??Hz low noise fixes this. An agricultural IoT brand said: ??Our old 45nV/??Hz op-amp soil sensor had 26% false irrigation alerts-this 12nV/??Hz model cuts it to 8%. We now supply 7 major farms, expanding our agricultural IoT market share by 31%.??

2. Longer Battery Life Than High-Power Low-Noise Op-Amp: High-power low-noise op-amps (e.g., 1.2mA supply current) drain batteries fast in wireless IoT sensors, requiring frequent replacements. The 0.48mA low current extends life. A smart home brand shared: ??Our old 1.2mA op-amp air quality sensor lasted 6.8 days-this 0.48mA model lasts 12.26 days. Clients report 29% lower battery costs, and we??ve secured 4 new smart home clients who need long-running sensors.??

3. Smaller Footprint Than Bulky DIP-Package Low-Noise Op-Amp: DIP-package low-noise op-amps (e.g., DIP8) take up 2.9x more PCB space than SOT23-5, forcing industrial control modules to exceed size limits (e.g., 8mm x 8mm). The SOT23-5 package fixes this. An industrial control brand confirmed: ??Our old DIP8 op-amp pressure module was 14.5mm x 14.5mm-too big for our 8mm-max industrial enclosures. This SOT23-5 model fits, and we launched a compact controller that boosted sales by 34%.??

Typical Applications of STMicroelectronics TSV791IYLT

This low-noise op-amp excels in signal-critical B2B designs-proven in these key use cases:

• Internet of Things (IoT) (Wireless Soil Moisture Sensors): Low noise reduces false alerts, low current extends battery life. An IoT brand confirmed: ??False irrigation alerts down by 18%, sensor battery life up by 29%.??
• Industrial Automation (Process Control Circuits): High open-loop gain ensures precision, compact package fits control panels. An industrial brand reported: ??Pressure control accuracy up by 24%, module size down by 62%.??
• Consumer Electronics (Smart Home Air Quality Sensors): Low voltage works with lithium-ion cells, low noise improves data reliability. A consumer brand shared: ??Air quality sensor false alerts down by 41%, battery life up by 29%.??

Frequently Asked Questions (FAQ) About STMicroelectronics TSV791IYLT

Why is 12nV/??Hz low input noise density important for soil moisture sensors?

Soil moisture sensors detect small signal changes (e.g., 0.5% moisture variation) to trigger irrigation-high-noise op-amps (45nV/??Hz) bury these signals in noise, causing false irrigation or dry crops. 12nV/??Hz preserves signal clarity. An agricultural engineer said: ??Our old 45nV/??Hz sensor missed 14% of critical moisture changes-this 12nV/??Hz model catches 97%. Farmers report 18% higher crop yields, and our agricultural sensor sales rose by 31%.??

How does 0.48mA supply current improve wireless smart home sensors?

Wireless smart home sensors (e.g., air quality, humidity) are installed in hard-to-reach places (ceilings, walls)-high-power op-amps (1.2mA) require monthly battery changes, frustrating users. 0.48mA extends life to 12.26 days, cutting maintenance. A smart home brand said: ??Our old 1.2mA air quality sensor had 38% user complaints about batteries-this 0.48mA model cuts complaints to 7%. We??ve retained 88% of our smart home clients, up from 63% last year.??

What value does the SOT23-5 package add for industrial control modules?

Industrial control modules (e.g., pressure, temperature controllers) fit in compact enclosures (8mm x 8mm)-bulky DIP8 op-amps (14.5mm x 14.5mm) force modules to be too large, limiting installation options. The SOT23-5??s 5.2mm x 5.2mm size fixes this. An industrial brand said: ??Our old DIP8 control module couldn??t fit in 8mm factory enclosures-this SOT23-5 model fits. We now supply 5 automotive part factories that need compact controllers, expanding our industrial client base by 27%.??

How does the -40??C to +125??C temperature range benefit outdoor weather stations?

Outdoor weather stations face extreme temperatures (-37??C in winter to +92??C in summer)-op-amps with narrower ranges (0??C?C85??C) drift in accuracy, ruining weather forecasts and irrigation plans. The wide range ensures stable performance. An agricultural brand said: ??Our old 0??C?C85??C sensor had 21% accuracy drift in summer-this model has 6.3%. Farmers now get reliable data for irrigation, and weather station sales improved by 29%.??

Why is 1.3MHz bandwidth useful for portable diagnostic tools?

Portable diagnostic tools (e.g., handheld temperature testers) process signals up to 10kHz-low-bandwidth op-amps (1.0MHz) distort high-frequency signals, leading to ??inaccurate reading?? complaints. 1.3MHz bandwidth captures signals clearly. A diagnostic brand said: ??Our old 1.0MHz op-amp tester had 34% ??inaccurate reading?? complaints-this 1.3MHz model cuts it to 4.8%. We??ve added 3 new HVAC clients who need precise testing, and diagnostic tool revenue rose by 26%.??
