TSX3702IYDT

Overview

The TSX3702IYDT is a micropower dual CMOS voltage comparator manufactured by STMicroelectronics. It features a typical supply current of 5 µA per comparator and operates within a wide single supply range of 2.7 V to 16 V or dual supplies from ±1.35 V to ±8 V. The device exhibits an extremely low input bias current of 1 pA typical and an input common-mode voltage range that includes ground. It provides a push-pull output with a high input impedance of 10^12 Ω typical. The response time is typically 2.7 µs for a 5 mV overdrive, and it offers ESD tolerance of 4 kV HBM and 200 V MM. The component is available in the MiniSO-8 package.

Procurement Notes

Verify the specific suffix IYDT corresponds to the MiniSO-8 package variant when sourcing. Confirm RoHS compliance status through official datasheets prior to integration. Ensure design margins account for the specified operating temperature range and supply voltage limits to maintain performance stability across all intended environmental conditions.

Selection Notes

Select this component for designs prioritizing ultra-low power consumption alongside general-purpose comparison capabilities. The inclusion of ground-referenced input common-mode voltage simplifies single-supply interface requirements. Consider the MiniSO-8 package for space-constrained layouts while ensuring thermal management aligns with the specified operating temperature range.
