Overview
The TSM982CSA+T is a dual ultra-low-power analog comparator manufactured by Silicon Labs, housed in an 8-pin SOIC package. 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 voltage with ±2% accuracy. It supports adjustable hysteresis via an external HYST pin and draws a maximum supply current of 6μA over the industrial temperature range.
Feature Summary
- Dual comparators with integrated 1.182V reference
- Ultra-low quiescent current consumption
- Open-drain output stages for wired-OR capability
- Adjustable hysteresis functionality
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
- Battery-powered systems
Procurement Notes
Verify the specific suffix CSA+T against official ordering tables to confirm the 8-pin SOIC package and commercial temperature range (0°C to +70°C). Ensure compatibility with the required supply voltage and load conditions before finalizing procurement.
Selection Notes
Select this component when dual comparators with an internal reference are needed in a compact surface-mount package. It is suitable for applications requiring low power consumption and adjustable hysteresis without external components.
Part Context
This part belongs to the TSM97x/98x family of micropower analog comparators. It serves as an alternate source for Maxim Integrated MAX982 devices, offering electrical and form-factor equivalence within the same product line.
Replacement Considerations
Public confirmed substitute: MAX982ESA+T
FAQ
How is hysteresis configured on the TSM982?
Hysteresis is adjusted using two external resistors connected between the REF, HYST, and V- pins.
What is the input common-mode voltage range?
The input common-mode voltage range extends from the negative supply rail (V-) to 1.3V below the positive supply rail (V+).
