TS882IYST

Overview

The TS882IYST is a dual analog comparator from STMicroelectronics, featuring rail-to-rail input and push-pull output capabilities. It operates on a single supply voltage ranging from 1.1 V to 5.5 V with a typical quiescent current of 220 nA per comparator at VCC = 1.2 V. The device offers a propagation delay of 2 µs (typical) and a response time of 13 µs. Key electrical parameters include an input offset voltage of 6 mV, input bias current of 100 pA, and a common-mode rejection ratio of 78 dB. It supports an output current of 1.7 mA per channel and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Ultra-low power consumption enabling extended battery life in portable devices
• Rail-to-rail input capability for maximum dynamic range utilization
• Push-pull output stage providing direct interfacing with digital logic

Applications

• Portable consumer electronics requiring minimal standby current
• Battery-powered measurement instruments
• Signal conditioning circuits in low-voltage systems

Procurement Notes

Verify the specific suffix 'IYST' corresponds to the MiniSO-8 package and industrial temperature grade (-40°C to +125°C). Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure ESD handling procedures are followed during assembly due to the nanometer-scale internal structures.

Selection Notes

Select this component when designing low-voltage systems requiring both high input impedance and rail-to-rail signal compatibility. The dual-channel configuration simplifies board space compared to single comparators. Consider the 2 µs propagation delay for timing-critical applications. Verify that the 1.7 mA output drive capability meets the load requirements of the subsequent circuit stage without external buffering.

Part Context

The TS882 belongs to the TS88x family of nanopower comparators, which also includes the quad version TS884. This family is designed specifically for applications where power efficiency is critical, such as mobile phones and wearable devices. The IYST designation indicates the industrial temperature range and MiniSO-8 surface-mount packaging format.
