Overview
The TSM932ESA+ is a dual-channel micropower analog comparator in an 8-SOIC package. It operates from single +2.5V to +11V or dual ±1.25V to ±5.5V supplies. The device features push-pull TTL/CMOS-compatible outputs capable of sourcing up to 40mA and sinking 5mA continuously. It includes an internal 1.182V ±2% voltage reference and adjustable hysteresis via the HYST pin. Maximum supply current is 6µA over temperature, with a propagation delay of 12µs at 10mV overdrive.
Feature Summary
- Dual comparators with integrated 1.182V reference
- Push-pull outputs for direct logic interfacing
- Adjustable external hysteresis capability
- Low quiescent current consumption
Applications
- Threshold detectors
- Window comparators
- Level translators
- Battery-powered systems
Procurement Notes
Verify the specific suffix 'ESA+' corresponds to the industrial temperature range (-40°C to +85°C) and SOIC-8 package. Confirm lead-free status as per manufacturer standards. Check datasheet revision history for any packaging label updates or component changes that may affect compatibility.
Selection Notes
Select this part when dual independent comparison is required within a compact footprint. The integrated reference simplifies circuit design by reducing external component count. Ensure the application requires the specific output drive capabilities and input common-mode range provided by this family.
Part Context
This component belongs to the TSM93x family, which serves as an alternate source for the MAX931-MAX934 series. The family includes single, dual, and quad variants sharing identical electrical characteristics and form factors. The TSM932 specifically provides two comparators in an 8-pin configuration.

FAQ
How is hysteresis configured on the TSM932?
Hysteresis is added externally using two resistors connected to the HYST pin. Connecting HYST to REF disables hysteresis.
What is the input voltage range?
The input voltage range extends from the negative supply rail (V-) to within 1.3V of the positive supply rail (V+).
