Overview
The LM2901A-SO2R-S is a quad independent comparator from the 3PEAK LM2901A/LM2903A series, housed in an SOP14 package. It operates on a single supply of +2.5 V to +36 V or dual supplies of ±1.25 V to ±18 V. Key electrical specifications include a maximum input offset voltage of ±7.0 mV and a maximum input bias current of 1 nA at 25°C. The quiescent current per comparator ranges from 100 μA to 300 μA across the operating temperature range of –40°C to 125°C. Response time is specified at 0.5 μs for TTL-level input steps.
Feature Summary
- Automotive qualification with AEC-Q100 reliability test compliance
- Wide single-supply voltage range up to 36 V or dual supplies up to ±18 V
- Low power consumption suitable for battery operation
- Direct interface capability with TTL and CMOS logic
Applications
- High-speed line or digital line receivers
- Peak and zero-crossing detectors
- High-speed sampling circuits
- HEV/EV systems
Procurement Notes
Verify the specific ordering suffix SO2R-S corresponds to the SOP14 package and tape-and-reel quantity of 2500 units as listed in the official order information table. Confirm that the component meets RoHS compatibility and halogen-free requirements defined by the manufacturer's green product standards before finalizing procurement specifications.
Selection Notes
Select this component when a quad comparator configuration is required within a compact SOP14 footprint. Ensure the application demands low input bias current and wide common-mode voltage range including ground. Verify that the supply voltage constraints align with the 2.5 V to 36 V operational limits and that the automotive qualification status is necessary for the target environment.
Part Context
This part belongs to the LM2901A/LM2903A family of 36-V low power comparators manufactured by 3PEAK. The series includes dual (LM2903A) and quad (LM2901A) variants available in multiple packages such as SOP8, TSSOP8, MSOP8, SOP14, and TSSOP14. The LM2901A specifically provides four independent comparators on a single monolithic substrate.
Replacement Considerations
Publicly confirmed substitute part numbers are not provided in the source material.
