TS882IQ2T

Overview

The TS882IQ2T is a dual analog comparator manufactured by STMicroelectronics, designed for low-power portable applications. It features rail-to-rail input and push-pull output capabilities, operating within a supply voltage range of 1.1 V to 5.5 V. The device draws an ultra-low quiescent current of 220 nA per comparator at VCC = 1.2 V with no load. Key electrical parameters include a typical propagation delay of 2 µs, maximum response time of 13 µs, input offset voltage of 6 mV, and input bias current of 100 pA. Each channel provides an output current of 1.7 mA. It operates across a wide temperature range from -40 °C to +125 °C and is housed in a DFN-8 surface-mount package.

Feature Summary

• Ultra-low power consumption enabling extended battery life in portable devices
• Rail-to-rail input capability allowing full signal swing utilization
• Push-pull output stage providing direct drive capability without external pull-up resistors
• High ESD tolerance ensuring robustness against electrostatic discharge events

Applications

• Battery-powered portable consumer electronics
• Signal conditioning circuits requiring minimal leakage current
• Low-voltage threshold detection systems
• General-purpose comparison tasks in space-constrained designs

Procurement Notes

Verify the specific suffix IQ2T corresponds to the DFN-8 package and reel/cut-tape availability as listed by authorized distributors. Confirm RoHS compliance status through official documentation before integration. Ensure design margins account for the specified input offset voltage and bias current variations across the industrial temperature range to maintain accuracy in critical sensing applications.

Selection Notes

Select this component when system requirements demand minimal static current draw alongside rail-to-rail input compatibility. It is suitable for designs where push-pull outputs simplify circuit topology by eliminating external components. Consider the 1.1 V minimum supply voltage constraint for battery-operated systems that may experience significant voltage droop during discharge cycles compared to higher-voltage alternatives.

Part Context

This part belongs to the TS882/TS884 family of nanopower comparators from STMicroelectronics. The TS882 variant specifically offers two independent channels, whereas the TS884 provides four. Both share identical electrical characteristics and low-power architecture, differing primarily in channel count and available package options such as MiniSO8, DFN8, SO14, TSSOP14, and QFN16.

Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly documented in the provided source material. Engineers should consult manufacturer cross-reference tools or datasheets for equivalent general-purpose, low-power dual comparators with compatible pinouts and electrical specifications.
