Texas Instruments LM258AMDREPG4

Overview

LM258AMDREPG4 from Texas Instruments is a dual operational amplifier designed for single- or dual-supply operation across –55°C to 125°C. It delivers 0.3 V/µs slew rate, 0.7 MHz unity-gain bandwidth, and 2 mV typical input offset voltage, with rail-to-rail input common-mode range including ground-enabling direct low-side current sensing in industrial power monitoring systems.

For engineers reviewing the LM258AMDREPG4 datasheet, LM258AMDREPG4 pinout, LM258AMDREPG4 application, or LM258AMDREPG4 equivalent, key selection criteria include extended temperature support, ±32 V differential input voltage tolerance, low 0.7 mA supply current per amplifier, and SOIC-8 packaging compatible with high-reliability aerospace and downhole instrumentation designs.

Technical Context

The LM258AMDREPG4 integrates two independent, internally frequency-compensated op-amps optimized for wide-supply operation (3 V to 30 V single supply or ±1.5 V to ±15 V dual supply). Its input stage supports common-mode voltages down to ground and up to VCC – 2 V, enabling direct interfacing with sensors and ADC drivers without level-shifting circuitry.

Each amplifier features 100 V/mV typical open-loop gain, 70 dB minimum CMRR, and 65 dB minimum PSRR-making it suitable for precision dc amplification blocks where supply ripple rejection and signal integrity at low frequencies are critical in analog front-ends for data acquisition modules.

FAQ

What is the maximum supply voltage rating for LM258AMDREPG4?

The LM258AMDREPG4 supports a maximum supply voltage of ±16 V for dual supplies or 32 V for single supply, as specified in its Absolute Maximum Ratings table. This 32-V capability enables direct interface with 24-V industrial buses and high-voltage sensor excitation circuits without external regulation. Exceeding this limit risks permanent damage, and operation above 30 V is not recommended for sustained use per the Recommended Operating Conditions.

Does LM258AMDREPG4 support rail-to-rail output swing?

No, LM258AMDREPG4 does not provide rail-to-rail output swing. Its high-level output voltage is typically 26 V at VCC = 30 V and RL = 2 kΩ, and low-level output is typically 20 mV above ground under similar conditions. This ~1.5 V headroom on each rail limits dynamic range in low-voltage single-supply systems but remains sufficient for interfacing with 12-bit ADCs referenced to 2.5 V or 3.3 V.

Is LM258AMDREPG4 pin-compatible with standard LM258 variants?

Yes, LM258AMDREPG4 uses the industry-standard SOIC-8 (D) package with identical pinout to commercial LM258 and LM2904 devices. Pin assignments-including dual amplifier inputs/outputs, shared VCC and GND-match TI's generic dual op-amp layout. This allows drop-in replacement in existing designs, provided thermal and reliability requirements align with the enhanced product (EP) qualification level.

What is the input common-mode voltage range of LM258AMDREPG4?

The input common-mode voltage range of LM258AMDREPG4 extends from ground (0 V) to VCC – 2 V across the full temperature range. At VCC = 5 V, this yields 0 V to 3 V; at VCC = 30 V, it spans 0 V to 28 V. This ground-sensing capability eliminates the need for negative supplies in single-ended sensor interfaces and simplifies biasing of resistive transducers like RTDs and strain gauges.

How is LM258AMDREPG4 qualified for extended temperature operation?

LM258AMDREPG4 undergoes JEDEC-compliant qualification including Highly Accelerated Stress Test (HAST), temperature cycling, autoclave, electromigration, bond intermetallic life, and mold compound life testing. These tests verify reliability over –55°C to 125°C operation and support its use in downhole tools, avionics, and space-constrained industrial controls where thermal cycling exceeds commercial-grade limits.
