LM258DT

Overview

The LM258DT is a dual low-power operational amplifier manufactured by STMicroelectronics, housed in an 8-pin SOIC surface-mount package. It features a gain-bandwidth product of 1.1 MHz and a slew rate of 600 mV/µs. The device operates on a supply voltage range of 3 V to 30 V with a typical supply current of 700 µA. Key electrical parameters include an input offset voltage of 1 mV, input bias current of 20 nA, and output current capability of 40 mA per channel. It supports a common-mode rejection ratio of 70 dB and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Internally frequency compensated for stability without external components
• Single-supply operation compatible with standard logic voltages
• Input common-mode voltage includes ground potential
• Output voltage swings to ground even on single supplies

Applications

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

Procurement Notes

Verify the specific suffix 'DT' corresponds to the tape-and-reel packaging format as indicated by distributor listings. Confirm RoHS compliance status and AEC-Q100 automotive qualification requirements against the latest manufacturer datasheet before finalizing procurement specifications.

Selection Notes

Select this component when low power consumption is critical alongside single-supply compatibility. The internal frequency compensation simplifies circuit design by eliminating external compensation networks. Ensure the required output swing to ground aligns with the application's signal processing needs.

Part Context

This part belongs to the LM258 series of low-power dual operational amplifiers. It is designed for applications requiring high gain and wide bandwidth while maintaining low supply current independent of the supply voltage magnitude. The series is widely used in general-purpose analog signal processing tasks.
