Overview
The TSM932CSA+T is a dual-channel analog comparator from the TSM93x family, manufactured by Silicon Labs. It operates on single supplies of +2.5V to +11V or dual supplies of ±1.25V to ±5.5V. The device features push-pull TTL/CMOS-compatible outputs capable of sourcing up to 40mA and sinking 5mA continuously. It includes an internal 1.182V ±2% voltage reference and adjustable hysteresis via a dedicated pin. Quiescent current is typically 4.5µA at +25°C and max 6µA over temperature. Propagation delay is 12µs at 10mV overdrive. Input offset voltage is ±10mV. It is housed in an 8-pin SOIC package.
Feature Summary
- Dual comparators with integrated 1.182V reference
- Adjustable external hysteresis capability
- Push-pull outputs for direct logic interfacing
- Ultra-low quiescent current consumption
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
- Battery-powered systems
Procurement Notes
Verify the ordering suffix '+T' corresponds to the Tape & Reel carrier configuration as specified in the datasheet. Confirm the 'C' designation indicates the commercial operating temperature range of 0°C to +70°C. Ensure compatibility with the required supply voltage range and output drive requirements before finalizing procurement.
Selection Notes
Select this component when a dual-channel comparator with an internal reference is required. It is suitable for applications needing adjustable hysteresis without complex feedback networks. Consider the 8-pin SOIC package constraints and the specific input common-mode voltage range extending to the negative rail.
Part Context
This part belongs to the TSM931-TSM934 family of ultra-low-power comparators. It is electrically and form-factor identical to the Maxim Integrated MAX932. The family offers single, dual, and quad configurations with varying numbers of comparators per package.
Replacement Considerations
The TSM932CSA+T is functionally equivalent to the MAX932CSA+T. Verify pinout and electrical specifications match exactly before substitution.
