Overview
The TSM982CUA+T is a dual-channel analog comparator from the TSM97x/98x family, manufactured by Touchstone Semiconductor (Silicon Labs). It operates on single supplies of +2.5V to +11V or dual supplies of ±1.25V to ±5.5V. The device features open-drain outputs and an internal 1.182V reference with ±2% accuracy. Key electrical parameters include a maximum propagation delay of 12µs at 10mV overdrive, a maximum supply current of 6µA, and adjustable hysteresis capability.
Feature Summary
- Dual comparators with integrated 1.182V voltage reference
- Open-drain output stages enabling wired-OR configurations
- Adjustable external hysteresis via dedicated HYST pin
- Ultra-low quiescent current consumption for battery applications
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
- Battery-powered systems
Procurement Notes
Verify the manufacturer designation as Touchstone Semiconductor or Silicon Laboratories Inc. Confirm the package type is 8-pin MSOP/SOIC. Ensure the suffix indicates tape and reel packaging if required. Check for lead-free compliance status. Validate that the specific part number matches the dual-channel configuration with reference.
Selection Notes
Select this component when dual comparators with an internal reference are needed in a small footprint. It is suitable for low-voltage single-supply designs down to 2.5V. The open-drain output requires an external pull-up resistor. Verify that the input common-mode range extends to the negative rail.
Part Context
This part belongs to the TSM97x/98x series of ultra-low-power comparators. It serves as an alternate source for the Maxim MAX982. The family includes single, dual, and quad variants with varying reference accuracies and hysteresis options. The TSM982 specifically offers dual channels with a ±2% accurate reference.

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 voltage range extends from the negative supply rail (V-) to within 1.3V of the positive supply rail (V+).
