Overview
The TSM923CUA+ is a dual-channel, ultra-low-power analog comparator manufactured by Silicon Labs. It operates from 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 with a continuous source current capability of 40mA. It includes an internal 1.182V ±1% voltage reference and supports adjustable external hysteresis via a dedicated pin. Propagation delay is 12μs at 10mV overdrive.
Feature Summary
- Ultra-low quiescent current consumption for battery-powered applications
- Integrated 1.182V precision voltage reference
- Adjustable external hysteresis functionality
- Push-pull output stage capable of sourcing up to 40mA
Applications
- Threshold Detectors
- Window Comparator
- Level Translators
- Oscillator Circuits
- Battery-Powered Systems
Procurement Notes
Verify the specific suffix 'CUA+' corresponds to the commercial temperature range (0°C to +70°C) and 8-pin MSOP/SOIC package as defined in the ordering information. Confirm that the lead-free packaging aligns with project requirements. Ensure the supply voltage range matches the application's power constraints before finalizing procurement.
Selection Notes
Select this component when dual comparators are required alongside an internal reference voltage. It is suitable for low-voltage single-supply designs where minimizing external components is critical. The adjustable hysteresis feature makes it ideal for noisy environments requiring stable switching without complex feedback configurations.
Part Context
The TSM923CUA+ belongs to the TSM921-TSM924 family of micropower analog comparators. This family is electrically and form-factor identical to the Maxim Integrated MAX921-MAX924 series. The TSM923 specifically provides two comparators within a single package, offering a compact solution for dual-channel comparison tasks.
Replacement Considerations
The TSM923CUA+ is functionally equivalent to the Maxim Integrated MAX923CUA+. Designers transitioning between manufacturers can utilize these parts interchangeably due to their identical electrical characteristics and pinouts.
