TSX3702IQ2T

Overview

The TSX3702IQ2T 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, high input impedance of 10^12 Ω typical, and a fast response time of 2.7 µs typical for 5 mV overdrive. It includes push-pull outputs, input common-mode voltage range including ground, and ESD tolerance of 4 kV HBM and 200 V MM. The component is fully specified over a temperature range of -40°C to +125°C and is available in automotive grade.
