Product details
Overview
LM258ADRG4 from Texas Instruments is a dual operational amplifier optimized for industrial temperature range (–25°C to +85°C), featuring 3 V to 32 V supply operation, 7 mV maximum input offset voltage at 25°C, 350 µA typical quiescent current per amplifier, and 0.7 MHz unity-gain bandwidth - used in motor control feedback loops, power supply error amplifiers, and sensor signal conditioning circuits.
For engineers reviewing the LM258ADRG4 datasheet, LM258ADRG4 pinout, LM258ADRG4 application, or LM258ADRG4 equivalent, this page delivers verified electrical specs, SOIC-8 package details, real-world use cases, and two confirmed alternative parts with documented functional and thermal differences.
Technical Context
The LM258A is a bipolar-input dual op amp with rail-to-rail output swing capability near the negative rail (as low as 5 mV above V– at 25°C, 20 mV over full temperature range), enabling single-supply sensing of ground-referenced signals. Its internal compensation ensures unity-gain stability without external components.
It operates across a wide common-mode input range (V– to V+ – 1.5 V at VS = 30 V) and delivers 30 mA sink/source output drive into resistive loads, supporting direct interface with comparators, ADC drivers, and analog multiplexers in cost-sensitive embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 32 V - supports both single-supply (e.g., 5 V, 12 V, 24 V) and split-supply (±15 V) configurations without derating. |
| Input Offset Voltage (max) | 7 mV at 25°C - sets worst-case DC error in precision gain stages; requires <1.4% gain error correction in 100× non-inverting amplifier. |
| Unity-Gain Bandwidth | 0.7 MHz - limits closed-loop bandwidth to ~7 kHz at G = 100; suitable for <10 kHz signal conditioning but not audio or fast control loops. |
| Quiescent Current / Amp | 350 µA typical - enables low-power operation in battery-backed or energy-constrained systems (e.g., 2.8 mW total at 5 V). |
| Output Swing (V– side) | 5–20 mV above V– at full temperature range - allows accurate measurement of signals referenced to ground in single-supply designs. |
| Common-Mode Input Range | V– to (V+ – 1.5 V) at VS = 30 V - enables direct sensing of 0 V–referenced transducer outputs without level-shifting circuitry. |
| Open-Loop Gain | 25–100 V/mV (25–40 dB) - provides sufficient loop gain for stable closed-loop operation with moderate precision requirements. |
Pinout & Package
LM258ADRG4 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package measuring 4.90 mm × 3.90 mm, with standard JEDEC MS-012AC footprint and gull-wing leads for surface-mount assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives external load; capable of ±20 mA source/sink into resistive loads. |
| 2 | IN1– | Inverting input of Amp 1 - high-impedance node (ZIC = 4 GΩ||1.5 pF); sensitive to PCB leakage and EMI. |
| 3 | IN1+ | Non-inverting input of Amp 1 - same impedance as IN1–; accepts common-mode voltages down to V–. |
| 4 | V– | Negative supply or ground reference - must be low-impedance; shared return path for both amplifiers. |
| 5 | IN2+ | Non-inverting input of Amp 2 - electrically isolated from Amp 1 inputs; supports independent signal paths. |
| 6 | IN2– | Inverting input of Amp 2 - matched bias current to IN1–; enables dual-channel differential or instrumentation topologies. |
| 7 | OUT2 | Amplifier 2 output - identical drive capability to OUT1; usable for cascaded gain stages or dual-sensor interfaces. |
| 8 | V+ | Positive supply - supplies both amplifiers; decoupling capacitor (0.1 µF ceramic) required within 1 cm. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output near V– | 5–20 mV above V– over full temperature range - eliminates need for negative supply in ground-sensing applications like current shunt monitoring. |
| Wide common-mode input range | V– to (V+ – 1.5 V) at VS = 30 V - permits direct connection of thermocouples, bridge sensors, or DAC outputs without level shifters. |
| Internal frequency compensation | Unity-gain stable - removes requirement for external compensation networks, reducing BOM count and layout complexity. |
| High ESD tolerance | ±500 V HBM - meets basic handling requirements for manual assembly and board-level rework without special precautions. |
| Low input bias current | –20 nA to –250 nA (typical) - minimizes voltage error across high-impedance sources (e.g., pH electrodes, photodiodes). |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358ADR | Same SOIC-8 package; wider temp range (0°C to 70°C), higher VOS (7 mV max), identical 0.7 MHz GBW and 350 µA IQ. | Not rated for industrial –25°C cold start; suitable only for commercial indoor environments. | Select when ambient operating temperature stays above 0°C and cost is prioritized over extended range. |
| LM2904DR | SOIC-8; automotive-grade (–40°C to 125°C), same VOS (7 mV max), but lower supply limit (3 V to 26 V) and no integrated EMI filter. | Valid for under-hood automotive ECUs; lacks RF/EMI filtering needed in noisy industrial motor drives. | Choose for automotive qualification requirements where extended high-temp operation is mandatory. |
Compared with LM258ADRG4, LM358ADR trades industrial temperature support for broader commercial availability, while LM2904DR adds automotive qualification at the expense of supply voltage headroom and EMI robustness - making LM258ADRG4 optimal for fixed-location industrial equipment requiring –25°C startup and 32 V headroom.

FAQ
What is the operating temperature range for LM258ADRG4?
The LM258ADRG4 is specified for operation from –25°C to +85°C ambient temperature. This industrial-grade range supports deployment in factory automation, HVAC controls, and outdoor-rated power supplies where environmental extremes exceed commercial limits but fall short of automotive or military requirements. The LM258ADRG4 maintains its 7 mV maximum input offset voltage and 0.7 MHz bandwidth across this full span.
Does LM258ADRG4 support single-supply operation?
Yes, LM258ADRG4 supports true single-supply operation with common-mode input range extending to the negative rail (V–) and output swing within 5–20 mV of V–. This enables direct interfacing with ground-referenced sensors such as current shunts, thermocouples, or bridge transducers without level-shifting circuitry - a key advantage over older op amps that require dual supplies for similar functionality.
What package type is used for LM258ADRG4?
LM258ADRG4 uses an 8-pin SOIC (Small Outline Integrated Circuit) package with JEDEC MS-012AC outline, body size 4.90 mm × 3.90 mm. It features gull-wing leads compatible with standard SMT reflow profiles and is pin-compatible with other dual op amps in the LMx58/LMx904 family, simplifying board design reuse and second-source qualification.
How does LM258ADRG4 compare to LM358ADR in terms of performance?
LM258ADRG4 and LM358ADR share identical electrical specs (7 mV VOS max, 0.7 MHz GBW, 350 µA IQ) and SOIC-8 packaging, but differ in temperature rating: LM258ADRG4 operates from –25°C to +85°C, while LM358ADR is limited to 0°C to +70°C. Both lack integrated EMI filtering and are functionally interchangeable where ambient conditions permit - making LM258ADRG4 the preferred choice for cold-start industrial deployments.
Can LM258ADRG4 drive capacitive loads directly?
LM258ADRG4 is characterized for stable operation with up to 100 pF capacitive load, as confirmed in TI's SLOS068W datasheet. Driving larger loads (e.g., >200 pF cables or ADC input capacitance) requires isolation via a series resistor (typically 10–100 Ω) or external compensation to prevent peaking or oscillation - especially critical in high-precision sensor front-ends where phase margin degradation affects settling time.
