Overview
The TSM933CSA+T is a dual-channel analog comparator from Silicon Labs, packaged in an 8-pin SOIC. It operates on single supplies of +2.5V to +11V or dual supplies of ±1.25V to ±5.5V. The device features ultra-low quiescent current of 6μA maximum over temperature and includes an internal 1.182V ±2% voltage reference. It provides push-pull TTL/CMOS-compatible outputs with continuous source current capability up to 40mA and adjustable hysteresis via an external pin.
Feature Summary
- Dual comparators with integrated 1.182V reference
- Ultra-low power consumption suitable for battery systems
- Push-pull outputs capable of sourcing 40mA continuously
- Adjustable hysteresis functionality
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
- Battery-powered systems
Procurement Notes
Verify the specific suffix 'T' indicates tape and reel packaging containing 2500 units per carrier. Confirm the 'C' designation corresponds to the commercial operating temperature range of 0°C to +70°C. Ensure compatibility with existing MAX933 designs as this component serves as an alternate source.
Selection Notes
Select this part when dual comparators are required alongside a precise internal reference voltage. It is suitable for applications needing high output drive current without external transistors. Consider the 8-pin SOIC package constraints and verify that the input common-mode range meets the system's signal requirements relative to the supply rails.
Part Context
This component belongs to the TSM931-TSM934 family of low-voltage micropower analog comparators. It is electrically and form-factor identical to the Maxim Integrated MAX933 series. The family offers flexibility through single or dual supply operation and varying channel counts across the product line.
Replacement Considerations
The TSM933CSA+T is designed as a direct electrical and physical replacement for the Maxim Integrated MAX933CSA+. Verify that the original design utilizes the same 8-pin SOIC footprint and supply voltage specifications.
