LM258AWYST

Overview

The LM258AWYST is a dual operational amplifier from STMicroelectronics, designed for low-power applications. It features two independent, high-gain channels with internal frequency compensation. The device operates on a single power supply ranging from 3 V to 30 V. Key electrical parameters include a gain-bandwidth product of 1.1 MHz and a slew rate of 600 mV/µs. Input bias current is specified at 50 nA, with an input offset voltage of 3 mV. The output can swing to ground, and the common-mode input range includes the negative rail.

Feature Summary

• Single-supply operation capability allowing direct interface with standard logic systems without additional power supplies.
• Input common-mode voltage range includes ground, enabling output voltage swing to ground even in single-supply configurations.
• Low power supply drain that remains essentially independent of the magnitude of the power supply voltage.

Applications

• Transducer amplifiers
• DC gain blocks
• Conventional op-amp circuits implemented in single power supply systems

Procurement Notes

Verify the specific suffix AWYST against official STMicroelectronics documentation to confirm package type and automotive qualification status. Ensure compatibility with required operating temperature ranges and pinout configurations before integration into designs.

Selection Notes

Select this component for designs requiring low quiescent current and single-supply functionality. The internal frequency compensation simplifies circuit design by ensuring stability without external components. Consider the 1.1 MHz bandwidth for moderate-speed signal processing tasks.
