Overview
The LM2903A-TS1R-S is a dual differential comparator manufactured by 3PEAK, housed in an MSOP8 surface-mount package. It operates on a single supply voltage ranging from +2.5 V to +36 V or dual supplies of ±1.25 V to ±18 V. The device features extremely low power consumption with a supply current of 150 μA per channel, independent of the supply voltage. Key electrical characteristics include a maximum input bias current of 1 nA and a maximum offset voltage of ±6.0 mV. The input common-mode voltage range includes ground, and the internal differential input voltage range equals the supply voltage. It supports operation temperatures from -40°C to 125°C and offers ESD protection ratings of HBM 4 kV and CDM 2 kV.
Feature Summary
- Ultra-low power consumption suitable for battery-operated applications
- Input common-mode voltage range includes ground potential
- Direct interface compatibility with TTL and CMOS logic families
- Open-collector output capability allows wired-AND configuration
Applications
- Battery-powered sensing circuits
- Threshold detection systems
- Signal conditioning interfaces
Procurement Notes
Verify the specific suffix 'TS1R' against the official 3PEAK datasheet to confirm packaging details and reel specifications. Ensure the component matches the required MSOP8 footprint and temperature grade. Cross-reference the manufacturer part number with authorized distributor listings to confirm authenticity and current production status before procurement.
Selection Notes
Select this component when low quiescent current is critical alongside precise voltage comparison. The wide supply voltage range accommodates various system architectures. Consider the MSOP8 package for space-constrained designs requiring surface-mount assembly. Verify that the open-collector output requirements align with the downstream circuit pull-up configurations.
Part Context
This part belongs to the LM2903A series of low-power dual comparators from 3PEAK. It is functionally compatible with industry-standard LM2903 devices, offering similar performance metrics in a modern surface-mount package. The series is designed for general-purpose analog comparison tasks where power efficiency and wide operating voltage ranges are prioritized.
Replacement Considerations
The LM2903A-SR is a documented alternative from 3PEAK in an SOP8 package. Other manufacturers offer pin-compatible equivalents such as the NXP, STMicroelectronics, and Texas Instruments LM2903 variants. Verify pinout and electrical parameters match before substitution.
