Overview
The TSM922ESA+ is a dual ultra-low-power analog comparator from 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 draws less than 4μA total supply current over temperature and features push-pull outputs capable of sourcing up to 40mA. It includes TTL/CMOS-compatible outputs with crowbar-current-free switching and supports input voltage ranges including the negative supply rail.
Feature Summary
- Dual-channel configuration with ultra-low quiescent current consumption
- Push-pull output stages providing high continuous source current capability
- TTL and CMOS compatible logic levels for versatile interfacing
- Wide common-mode input 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 distributors or direct manufacturer channels. Confirm the specific suffix indicates the extended industrial temperature range (-40°C to +85°C). Ensure compatibility with existing PCB footprints and verify that the lead-free packaging meets project environmental requirements before finalizing procurement.
Selection Notes
Select this part when dual independent comparison is required within a low-power budget. It serves as a functional equivalent to the MAX922 family. Consider the 40mA output drive for direct load driving. Verify that the absence of internal hysteresis aligns with the circuit design, as external components are necessary for noise immunity.
Part Context
This component belongs to the TSM921-TSM924 family of micropower analog comparators. These devices share electrical characteristics and form factors with the MAX921-MAX924 series. The TSM922 specifically provides two comparators without an internal reference voltage, distinguishing it from the single and quad variants in the lineup.
Replacement Considerations
The datasheet confirms electrical and form-factor identity with the Maxim Integrated MAX922. Verify pinout compatibility and operating voltage ranges when substituting.
