Overview
The TSM982ESA+T is a dual ultra-low-power analog comparator manufactured by Silicon Labs, operating within a supply voltage range of +2.5V to +11V (single) or ±1.25V to ±5.5V (dual). It features an internal 1.182V reference with ±2% accuracy and adjustable hysteresis via the HYST pin. The device draws a maximum quiescent current of 6μA over temperature and provides open-drain outputs for wired-OR applications.
Feature Summary
- Dual comparators with integrated 1.182V reference
- Ultra-low quiescent current consumption
- Adjustable external hysteresis capability
- Open-drain output stages
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
- Battery-powered systems
Procurement Notes
Verify the specific suffix 'ESA' indicates the extended industrial temperature range (-40°C to +85°C) and SOIC-8 package configuration. Confirm lead-free status and ensure compatibility with existing board layouts designed for MAX97x/MAX98x equivalents before finalizing procurement orders.
Selection Notes
Select this component when dual-channel comparison with a precise internal reference is required without external resistor networks. The adjustable hysteresis feature makes it suitable for noisy environments where signal stability is critical. Ensure the application supports the open-drain output requirement and necessary pull-up configurations.
Part Context
This part belongs to the TSM971/972/973/982/984 family of micropower analog comparators. It serves as an alternate source for Maxim Integrated MAX982 devices, maintaining electrical and form-factor identity. The family is optimized for low-voltage single-supply applications such as 3V or 5V systems.

FAQ
How is hysteresis configured on the TSM982?
Hysteresis is adjusted using two external resistors connected between the REF, HYST, and V- pins. Connecting HYST directly to REF disables hysteresis.
What is the input common-mode voltage range?
The input common-mode voltage range extends from the negative supply rail (V-) to within 1.3V of the positive supply rail (V+).
