Overview
The TSM933CUA+ is a dual-channel analog comparator manufactured by Silicon Labs, designed for low-voltage and micropower applications. It operates from single supplies of +2.5V to +11V or dual supplies of ±1.25V to ±5.5V. The device features an internal 1.182V ±2% voltage reference and adjustable hysteresis via a dedicated pin. It draws a maximum supply current of 6μA over temperature and provides push-pull TTL/CMOS-compatible outputs capable of sourcing up to 40mA continuously. Propagation delay is 12μs at 10mV overdrive.
Feature Summary
- Dual comparators with integrated 1.182V reference
- Adjustable external hysteresis capability
- Push-pull output stages compatible with TTL and CMOS logic
- Ultra-low quiescent current consumption
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
- Battery-powered systems
Procurement Notes
Verify the specific suffix 'CUA+' against the datasheet to confirm the commercial temperature range (0°C to +70°C) and 8-pin MSOP/SOIC package type. Ensure the design accounts for the dual-supply configuration if V- is not grounded, as this affects output swing characteristics relative to the negative rail.
Selection Notes
Select this component when a dual-channel comparator with an onboard reference is required to minimize external parts count. It is suitable for designs needing adjustable hysteresis without complex feedback networks. Verify that the input common-mode voltage range meets the application's signal requirements relative to the power supply rails.
Part Context
This part belongs to the TSM93x family of ultra-low-power comparators, which are electrically and form-factor identical to the Maxim Integrated MAX931-MAX934 series. The TSM933 variant specifically integrates two comparators per package, distinguishing it from the single-channel TSM931 and quad-channel TSM934 models within the same product line.
Replacement Considerations
The TSM933CUA+ serves as an alternate source for the Analog Devices / Maxim Integrated MAX933CPA+. Both devices share identical electrical specifications and pinouts, allowing for direct substitution in existing designs without circuit modification.
