LM258AMDREP

Overview

The LM258AMDREP is a dual operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It features a gain-bandwidth product of 700 kHz and a slew rate of 0.3 V/µs. The device operates on supply voltages ranging from 3 V to 32 V single supply or ±1.5 V to ±16 V dual supply. Key electrical parameters include a typical input offset voltage of 2 mV, input bias current of 15 nA, and output current capability of 30 mA per channel. It supports an operating temperature range from -55°C to +125°C.

Feature Summary

• Dual independent high-gain frequency-compensated operational amplifiers designed for wide supply ranges
• Low supply-current drain that remains independent of the supply voltage level
• Common-mode input voltage range includes ground, enabling direct sensing near ground potential
• Rail-to-rail input type with differential input voltage range equal to maximum-rated supply voltage

Applications

• Temperature sensors and controllers using Modbus protocols
• Motor control applications including AC induction, brushed DC, brushless DC, and stepper motors
• Digital multimeter handheld field transmitters
• Chemical and gas sensor interfaces

Procurement Notes

Verify the complete part number including suffixes such as REPG4 when sourcing alternatives, as these indicate specific packaging or compliance variations. Confirm RoHS3 status and moisture sensitivity level MSL 1 requirements during storage and handling. Ensure the SOIC-8 footprint matches the design layout. Check for any recent PCN updates regarding assembly or material changes before finalizing procurement plans.

Selection Notes

Select this component for designs requiring low power consumption with wide single-supply operation. The rail-to-rail input capability makes it suitable for ground-referenced signal conditioning. Compare the 2 mV offset voltage against standard LM258 variants if higher precision is needed. Consider the 8-SOIC package dimensions for PCB space constraints. Verify thermal performance within the -55°C to +125°C range for industrial environments.

Part Context

This device belongs to the LM258A series, which offers improved specifications over the standard LM258. It is part of the broader family including LM158, LM358, and LM2904. The LM258A variant typically provides lower input offset voltage and bias current compared to non-A versions. It serves as a general-purpose dual op-amp solution widely used in analog signal processing circuits.

Replacement Considerations

LM258AMDREPG4 is listed as an alternative part number.
