Overview
The LM2903YPT is a dual low-power voltage comparator manufactured by STMicroelectronics, housed in an 8-pin TSSOP surface-mount package. It operates from a single supply voltage ranging from 2 V to 36 V or dual supplies of ±1 V to ±18 V. The device features a typical supply current of 0.4 mA and a maximum operating temperature of +125 °C. Key electrical parameters include a response time of 1.3 µs, an input bias current of 25 nA typ., and an output short-circuit current capability of 16 mA per channel.
Feature Summary
- Designed for operation from a wide range of single or split power supplies with input common-mode voltage including the negative rail
- Provides TTL, DTL, ECL, MOS, and CMOS compatible outputs with low output saturation voltage
- Automotive qualified under AEC-Q100 standards for reliable performance in vehicle applications
Applications
- Automotive electronic systems requiring qualified analog components
- Battery-powered equipment utilizing low supply current characteristics
- General-purpose signal conditioning and threshold detection circuits
Procurement Notes
Verify the specific suffix YPT corresponds to the TSSOP-8L packaging and tape-and-reel configuration required for your assembly line. Confirm that the automotive grade (AEC-Q100) meets your project's reliability specifications. Ensure compatibility with your PCB footprint dimensions for the 8-TSSOP package before finalizing procurement orders.
Selection Notes
Select this component when a dual comparator with automotive qualification and low power consumption is required. Consider the LM2903W if higher electrostatic discharge robustness is necessary for your environment. Evaluate the LM2903H if your application demands operation at temperatures exceeding 125 °C.
Part Context
This part belongs to the LM2903 series of dual comparators designed for low-power applications. It shares functional similarities with the LM193, LM293, and LM393 families but offers specific automotive certification and package options tailored for modern surface-mount manufacturing processes.
Replacement Considerations
The LM2903W serves as a substitute offering enhanced ESD protection. The LM2903H provides extended high-temperature operation capabilities.
