Overview
The TSM923CSA+ is a dual, low-voltage, micropower analog comparator from the TSM921–TSM924 family. It operates on single supplies of +2.5V to +11V or dual supplies of ±1.25V to ±5.5V. The device draws less than 2.5μA per comparator over temperature and features push-pull TTL/CMOS-compatible outputs capable of sourcing up to 40mA. It includes an internal 1.182V ±1% voltage reference and supports adjustable hysteresis via a dedicated pin.
Feature Summary
- Dual comparators with integrated 1.182V reference
- Adjustable external hysteresis capability
- Push-pull output stage with crowbar-current-free switching
- Ultra-low quiescent current consumption
Applications
- Threshold Detectors
- Window Comparator
- Level Translators
- Oscillator Circuits
- Battery-Powered Systems
Procurement Notes
Verify the 'C' suffix indicates the commercial operating temperature range of 0°C to +70°C. Confirm the 'SA+' designation corresponds to the 8-pin SOIC package in lead-free form. Ensure the specific ordering number matches the required carrier quantity for your production needs.
Selection Notes
Select this component when two independent comparators are required within a single package. The inclusion of an internal reference simplifies circuit design by reducing external component count. The adjustable hysteresis feature allows for noise immunity tuning without complex feedback configurations.
Part Context
This part belongs to the TSM921-TSM924 family of ultra-low-power comparators. It is electrically and form-factor identical to the MAX921-MAX924 family. The TSM923 specifically provides two comparators with an internal reference and hysteresis control, distinguishing it from the TSM922 which lacks these features.
Replacement Considerations
The datasheet states the TSM921-TSM924 family is electrically and form-factor identical to the MAX921-MAX924 family.
