TSM972ESA+T

Overview

The TSM972ESA+T is a dual analog comparator from Silicon Labs, operating on single +2.5V to +11V or dual ±1.25V to ±5.5V supplies. It draws a maximum of 4μA quiescent current over temperature and features open-drain outputs for wired-OR configurations. The device operates within an input common-mode voltage range from V- to V+ – 1.3V and exhibits a propagation delay of 12μs at 10mV overdrive.

Feature Summary

• Dual-channel architecture with ultra-low quiescent current consumption
• Open-drain output stages enabling wired-OR logic applications
• Wide input common-mode voltage range extending to the negative supply rail

Applications

• Threshold detectors
• Window comparators
• Level translators
• Oscillator circuits
• Battery-powered systems

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence notices. Confirm package integrity and pin alignment against the SOIC-8 outline drawing prior to assembly. Ensure power supply decoupling meets recommended layout practices to maintain signal stability.

Selection Notes

Select this component when dual independent comparison is required without internal reference voltages. It serves as an alternate source for the MAX972 family. Verify that the open-drain output configuration aligns with the pull-up requirements of the downstream circuitry.

Part Context

This device belongs to the TSM97x/98x family of low-voltage micropower analog comparators. It is electrically and form-factor identical to the Maxim Integrated MAX972. The family includes single, dual, and quad variants with varying reference and hysteresis capabilities.

Replacement Considerations

The TSM972ESA+T is functionally equivalent to the MAX972ESA+T. Verify pinout compatibility and electrical specifications before substituting.
