LM258AWYPT

Overview

The LM258AWYPT is a dual low-power operational amplifier manufactured by STMicroelectronics, housed in an 8-TSSOP surface-mount package. It features a gain-bandwidth product of 1.1 MHz and a slew rate of 600 mV/us. The device operates within a supply voltage range of 3 V to 30 V, with a maximum operating temperature of +105 C and a minimum of -40 C. Key electrical specifications include an input offset voltage of 3 mV, input bias current of 50 nA, and a common-mode rejection ratio of 85 dB. Each channel provides an output current capability of 40 mA while maintaining a low quiescent supply current of 700 uA.

Feature Summary

• Dual-channel architecture with internal frequency compensation for stable single-supply operation
• Rail-to-rail output swing capability allowing voltage levels down to ground potential
• Low power consumption profile independent of the magnitude of the supply voltage
• Automotive qualification compliant with AEC-Q100 standards

Applications

• Transducer amplifiers
• DC gain blocks
• Single power supply logic system interface electronics

Procurement Notes

Verify the specific suffix 'W' indicates the TSSOP-8 package variant and 'A' denotes the automotive grade classification. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering code matches the exact pinout and thermal requirements for the target PCB layout design.

Selection Notes

Select this component when automotive reliability and low power dissipation are required for dual-channel signal conditioning. The wide single-supply voltage range supports direct interfacing with standard logic systems without additional power rails. Consider the 3 mV input offset voltage specification for precision applications requiring minimal DC error correction.

Part Context

This part belongs to the LM258W series, which consists of two independent high-gain operational amplifiers designed for single-supply environments. The series is characterized by internally frequency-compensated circuits that simplify implementation in conventional op-amp configurations. It serves as a robust solution for general-purpose analog signal processing tasks in constrained power environments.
