TS882IST

Overview

The TS882IST is a dual analog comparator from STMicroelectronics, featuring rail-to-rail input and push-pull output capabilities. It operates within a supply voltage range of 1.1 V to 5.5 V and consumes a typical operating current of 220 nA per comparator at VCC = 1.2 V with no load. The device offers a propagation delay of 2 µs and supports an output current of 1 mA per channel. Input characteristics include a maximum offset voltage of 6 mV and bias currents of 100 pA. It functions reliably across a temperature range of -40 °C to +125 °C and is housed in a MiniSO-8 surface-mount package.

Feature Summary

• Ultra-low power consumption enabling extended battery life in portable devices
• Rail-to-rail input and output compatibility for wide signal swing handling
• Push-pull output stage eliminating the need for external pull-up resistors

Applications

• Battery-powered portable consumer electronics
• Signal conditioning circuits requiring low leakage
• General-purpose voltage monitoring systems

Procurement Notes

Verify the specific ordering suffix IST corresponds to the MiniSO-8 package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design specifications align with the absolute maximum ratings and thermal performance data provided in the official datasheet to guarantee long-term reliability under operational conditions.

Selection Notes

Select this component when rail-to-rail input/output functionality is required alongside minimal quiescent current. The push-pull output architecture simplifies circuit design by removing external pull-up requirements. Consider the 2 µs propagation delay and 6 mV offset voltage limits to ensure adequate speed and accuracy for the target application signals.

Part Context

This part belongs to the TS882x series of nanopower comparators designed for ultra-low energy applications. It complements other variants like the TS883IST, which features open-drain outputs instead of push-pull. The series targets markets demanding high efficiency and compact form factors in battery-operated systems.

Replacement Considerations

The TS883IST serves as a functional alternative within the same family but utilizes open-drain outputs rather than push-pull. Designers must account for the additional requirement of external pull-up resistors when substituting with the TS883IST variant.
