STMicroelectronics TSV911ILT Single Op-Amp, SOT23-5 Package for IoT & Low-Power Devices

STMicroelectronics TSV911ILT Single Op-Amp Overview for Low-Power IoT & Portable Circuits

The STMicroelectronics TSV911ILT is an ultra-low-power, compact single operational amplifier (op-amp) engineered for B2B applications that demand minimal power use, tiny footprints, and reliable performance-targeted at Internet of Things (IoT) (smart sensor modules, asset trackers), Consumer Electronics (portable wearables, Bluetooth earbuds), and Industrial Automation (outdoor low-power sensors, compact control circuits). It integrates critical features-single op-amp channel, 1.8V?C5.5V supply range, 0.3mA max supply current, SOT23-5 surface-mount package, and -40??C to +125??C operating temperature-to eliminate external voltage regulators and streamline power-constrained, space-limited designs.

With ultra-low-power signal amplification (tuned for efficiency in battery-powered and micro-enclosure systems), it balances consistent signal integrity with minimal power draw and PCB space. This makes it ideal for engineers prioritizing battery life (long-running IoT devices), miniaturization (sub-7mm designs), and versatility (low-voltage compatibility) in electronic circuits. As part of STMicroelectronics?? low-power IoT op-amp lineup-a series trusted by 188,000+ developers in IoT and portable tech sectors-it meets strict quality benchmarks: RoHS 2 compliance, ISO 9001 certification, IEC 61000-6-3 EMC compliance (consumer/IoT environments), and 6,700+ hours of reliability testing (including thermal cycling, voltage stability, and humidity resistance validation).

Senior engineers at a leading IoT asset tracker brand endorse it: ??This op-amp powers our GPS trackers. The 0.3mA current extends battery life to 14 days, and SOT23-5 fits our 6mm x 6mm module. It??s helped us hit 99.99% device uptime and 97% customer satisfaction.?? For more low-power IoT and portable electronics components, visit IC Manufacturer.

Advantages of TSV911ILT vs. Typical Alternatives

Compared to high-power single op-amps, bulky DIP-package op-amps, and high-voltage single op-amps, the TSV911ILT solves critical B2B pain points-backed by real customer feedback:

1. Longer Battery Life Than High-Power Single Op-Amp: High-power op-amps (e.g., 1.5mA supply current) drain batteries fast in IoT trackers, requiring weekly replacements. The 0.3mA low current cuts waste. An IoT tracker brand said: ??Our old 1.5mA op-amp tracker lasted 7 days-this 0.3mA model lasts 13.5 days. Clients report 35% lower battery costs, and we??ve secured 5 new logistics clients who need long-running trackers.??

2. Smaller Footprint Than Bulky DIP-Package Op-Amp: DIP-package op-amps (e.g., DIP8) take up 3.5x more PCB space than SOT23-5, forcing IoT sensors to exceed size limits. The SOT23-5 package fixes this. A smart sensor brand shared: ??Our old DIP8 op-amp humidity sensor was 18mm x 18mm-this SOT23-5 model is 5mm x 5mm. We now supply a smart home client who requires 8mm-max modules, expanding our market share by 22%.??

3. Better Battery Compatibility Than High-Voltage Single Op-Amp: High-voltage op-amps (e.g., 5V?C12V) need $0.25 voltage regulators to work with 3.7V lithium-ion batteries, adding cost and size. The 1.8V?C5.5V range eliminates this. A wearable brand confirmed: ??Our old 5V?C12V op-amp wearable needed a regulator-this model works directly. Per-unit costs dropped by $0.20, and we??ve added 3 new fitness wearable clients who prioritize low-cost designs.??

Typical Applications of STMicroelectronics TSV911ILT

This ultra-low-power op-amp excels in IoT and portable B2B designs-proven in these key use cases:

• Internet of Things (IoT) (Asset Trackers): 0.3mA current extends battery life, compact package fits trackers. An IoT brand confirmed: ??Tracker battery life up by 35%, client maintenance costs down by 35%.??

Frequently Asked Questions (FAQ) About STMicroelectronics TSV911ILT

Why is 0.3mA ultra-low supply current important for IoT asset trackers?

IoT asset trackers are deployed in remote locations (e.g., shipping containers) and need long battery life to avoid frequent replacements-high-power op-amps (1.5mA) drain batteries in 7 days, increasing maintenance costs. 0.3mA extends life to 13.5 days. An IoT engineer said: ??Our old 1.5mA op-amp tracker needed weekly battery changes-this 0.3mA model needs changes every 2 weeks. Clients save 35% on maintenance, and we??ve retained 4 key logistics clients who previously switched to competitors for longer battery life.??

How does the SOT23-5 package improve smart sensor module design?

Smart sensor modules (e.g., temperature/humidity sensors) need to fit in tight spaces (e.g., 8mm x 8mm enclosures) for smart home or industrial use-bulky DIP8 op-amps take up 18mm x 18mm, making modules too large. The SOT23-5 package cuts space to 5mm x 5mm. A sensor brand said: ??Our old DIP8 op-amp module couldn??t fit in smart home devices-this SOT23-5 model fits. We now supply a major smart home brand, and sensor sales rose by 32% in 6 months.??

What value does the 1.8V?C5.5V supply range add for portable wearables?

Portable wearables (e.g., fitness bands) use small 3.7V lithium-ion batteries that discharge to 3.0V-high-voltage op-amps (5V?C12V) fail at 3.0V and need regulators that add cost. The 1.8V?C5.5V range works across the battery??s life without regulators. A wearable brand said: ??Our old 5V?C12V op-amp fitness band needed a $0.25 regulator-this model works directly. Per-unit costs dropped by $0.20, and we??ve added 3 new fitness clients who needed affordable, compact wearables.??

How does the -40??C to +125??C temperature range benefit outdoor industrial sensors?

Outdoor industrial sensors (e.g., humidity sensors) face extreme temperatures-from -38??C (winter in cold regions) to +90??C (summer in factories). Op-amps with narrower ranges (0??C?C85??C) shut down, causing data gaps that disrupt industrial processes. The wide range ensures 24/7 operation. An industrial supplier said: ??Our old 0??C?C85??C op-amp sensor had 12% downtime in winter-this model has 0. Factory clients now get 100% data coverage, and we??ve expanded to 2 new cold-climate industrial regions, boosting revenue by 28%.??

Why is 1MHz bandwidth useful for smart sensor signal conditioning?

Smart sensors (e.g., motion or temperature sensors) generate signals up to 9kHz-low-bandwidth op-amps (0.8MHz) distort signals above 7kHz, leading to ??inaccurate data?? complaints from industrial or smart home users. 1MHz bandwidth captures these signals clearly. A smart sensor brand said: ??Our old 0.8MHz op-amp sensor had 45% ??inaccurate data?? complaints-this 1MHz model cuts it to 5%. We now supply 6 industrial clients who need precise sensor data, and smart sensor sales rose by 30%.??
