Overview
The TSM982ESA+ is a dual analog comparator from Silicon Labs, designed as an alternate source for the MAX982. It operates on single supplies from +2.5V to +11V or dual supplies of ±1.25V to ±5.5V. The device features open-drain outputs and includes an internal 1.182V reference with ±2% accuracy. It supports adjustable hysteresis via an external HYST pin. Maximum supply current is 6μA over temperature, with a propagation delay of 12μs at 10mV overdrive. It is housed in an 8-pin SOIC package.
Feature Summary
- Dual comparators with integrated 1.182V voltage reference
- Open-drain output stages enabling wired-OR configurations
- Adjustable hysteresis capability through dedicated input pin
- Ultra-low quiescent current consumption suitable for battery systems
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
- Battery-powered systems
Procurement Notes
Verify component authenticity against official datasheets due to its status as a second-source part. Confirm that the specific suffix matches the required operating temperature range and packaging format. Ensure compatibility with existing circuit designs referencing the original manufacturer's specifications before implementation.
Selection Notes
Select this component when dual comparators with an integrated reference are required. It is suitable for applications needing adjustable hysteresis and low power consumption. Verify that the open-drain output architecture aligns with the system logic levels and pull-up requirements.
Part Context
This part belongs to the TSM97x/98x family of micropower analog comparators. It is electrically and form-factor identical to the Maxim MAX982. The family includes single, dual, and quad variants with varying reference accuracies and hysteresis options.

FAQ
How is hysteresis configured on the TSM982?
Hysteresis is adjusted by connecting external resistors between the REF, HYST, and V- pins. Connecting HYST directly to REF disables hysteresis.
What is the maximum supply voltage for the TSM982?
The device supports a single supply voltage range up to +11V or a dual supply range up to ±5.5V.
