TS881ILT

TS881ILT Description

The TS881ILT from STMicroelectronics is a general-purpose comparator designed for precision applications requiring ultra-low power consumption and high performance. Packaged in a compact SOT23-5 form factor and available in Tape & Reel (TR), it is optimized for surface-mount designs. With a wide supply voltage range (0.85V to 5.5V) and quiescent current as low as 500nA, it is ideal for battery-operated and energy-sensitive systems. The device offers low input offset voltage (max 6mV @ 5V) and minimal input bias current (max 10pA), ensuring accuracy in signal detection and threshold applications.

TS881ILT Features

• Ultra-Low Power: Quiescent current of 500nA (max) extends battery life in portable devices.
• High Precision: 6mV max input offset voltage and 4.2mV hysteresis enhance stability and noise immunity.
• Robust Performance: 78dB CMRR minimizes common-mode interference, while 36mA output current supports direct driving of LEDs or small relays.
• Fast Response: 22µs max propagation delay ensures quick decision-making in real-time systems.
• Wide Voltage Range: Operates from 0.85V to 5.5V, compatible with low-voltage and standard logic levels.
• Reliable Compliance: ROHS3 Compliant and REACH Unaffected, meeting environmental and regulatory standards.

TS881ILT Applications

• Battery-Powered Devices: Ideal for wearables, IoT sensors, and energy harvesters due to ultra-low power consumption.
• Threshold Detection: Used in window comparators, overvoltage/undervoltage monitors, and zero-crossing detectors.
• Signal Conditioning: Enhances ADC front-ends, oscillators, and pulse generators with its high CMRR and precision.
• Consumer Electronics: Suitable for touchscreens, audio equipment, and power management circuits requiring fast response.
• Industrial Systems: Deployed in PLC inputs, motor control, and safety interlocks due to robustness and hysteresis.
