Product details
Overview
LM258PG4 from Texas Instruments is a dual operational amplifier optimized for industrial and consumer applications operating from 3 V to 32 V supply, featuring 5 mV maximum input offset voltage at 25°C, 0.7 MHz unity-gain bandwidth, and rail-to-rail output swing capability near the negative rail-enabling direct ground-sensing in sensor signal conditioning circuits.
For engineers reviewing the LM258PG4 datasheet, LM258PG4 pinout, LM258PG4 application, or LM258PG4 equivalent, key selection criteria include its –25°C to +85°C temperature range, SOIC-8 packaging, 350 µA typical quiescent current per amplifier, and compatibility with single-supply systems requiring common-mode input down to ground.
Technical Context
The LM258PG4 implements two independent high-voltage op amps in a single monolithic IC, each with internal frequency compensation for unity-gain stability. Its input stage supports common-mode voltages extending to the negative supply rail, and its output stage delivers asymmetric swing-within 20 mV of V– and up to 1.5 V below V+ under 10 kΩ load.
This device belongs to the legacy LMx58 family and shares pinout and functional behavior with LM358/LM2904 variants but is specifically rated for –25°C to +85°C operation and specified with 5 mV max VOS (vs. 7 mV for standard LM358), making it suitable for cost-sensitive analog front-ends where moderate precision suffices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 32 V - supports wide-input industrial power rails and battery-backed systems without external regulation |
| Input Offset Voltage (max) | 5 mV at 25°C - enables accurate DC-coupled amplification in low-gain sensor interfaces |
| Unity-Gain Bandwidth | 0.7 MHz - sufficient for anti-aliasing, active filtering, and medium-speed control loop compensation |
| Quiescent Current (typ) | 350 µA per amplifier - allows dual-channel amplification in power-constrained embedded systems |
| Common-Mode Input Range | Includes V– (ground) - permits direct interfacing with resistive sensors, thermistors, and current-sense shunts |
| Output Swing (V– side) | 5–20 mV above V– at TA = –25°C to +85°C - ensures usable dynamic range in single-supply configurations |
| Operating Temperature | –25°C to +85°C - qualified for commercial/industrial environments excluding extended automotive or military extremes |
Pinout & Package
LM258PG4 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package measuring 4.90 mm × 3.90 mm, with gull-wing leads and standard JEDEC MS-012AC footprint. The package is RoHS-compliant and rated for surface-mount reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Output of first operational amplifier - drives loads up to ±30 mA, with rail-swing capability near V– |
| 2 | IN1– | Inverting input of first op amp - high-impedance node (≥10 MΩ) for feedback network connection |
| 3 | IN1+ | Non-inverting input of first op amp - accepts signals down to V–, enabling true single-supply sensor biasing |
| 4 | V– | Negative supply or ground reference - shared return path for both amplifiers and external circuitry |
| 5 | IN2+ | Non-inverting input of second op amp - electrically isolated from IN1+, supports independent channel configuration |
| 6 | IN2– | Inverting input of second op amp - used for differential gain stages or active filter topologies |
| 7 | OUT2 | Output of second operational amplifier - identical electrical characteristics to OUT1, fully interchangeable |
| 8 | V+ | Positive supply rail - accepts up to 32 V DC; decoupling capacitor required within 1 cm for stability |
Key Features
| Feature | Design Value |
|---|---|
| Ground-sensing input stage | Common-mode range includes V–, eliminating need for level-shifting in single-supply transducer interfaces |
| Rail-to-rail output (low side) | Swings within 20 mV of V– across full temperature range, preserving headroom in 3.3 V or 5 V systems |
| Internal frequency compensation | Stable at unity gain without external components - simplifies design of buffers, followers, and integrators |
| High ESD robustness | ±500 V HBM rating - withstands handling and board-level electrostatic events in automated assembly |
| Low input bias current | ≤250 nA (max) - minimizes error in high-impedance source applications such as photodiode amplifiers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358P | Same SOIC-8 package; wider temp range (0°C to 70°C); 7 mV max VOS vs. 5 mV for LM258PG4 | Suitable for general-purpose lab equipment and non-critical consumer electronics where offset tolerance is relaxed | Select LM358P only if ambient operating temperature stays ≥0°C and higher offset is acceptable |
| LM2904DR | SOIC-8; extended temp range (–40°C to 125°C); same 7 mV max VOS; no integrated EMI filter | Preferred for automotive body-control modules and industrial PLC I/O where cold-start or high-temp reliability is mandatory | Choose LM2904DR when operating below –25°C or above +85°C is required; verify layout EMI mitigation separately |
Compared with LM358P and LM2904DR, the LM258PG4 offers tighter offset (5 mV) and intermediate temperature qualification (–25°C to +85°C), making it optimal for industrial appliances and commercial power systems where precision exceeds LM358P but extended temp range is unnecessary.

FAQ
What is the maximum supply voltage for LM258PG4?
The LM258PG4 supports a maximum supply voltage of 32 V across the V+ to V– terminals, as specified in its Absolute Maximum Ratings table. This rating applies to continuous DC operation under recommended conditions and enables use in 24 V industrial systems and wide-input power adapters. Exceeding 32 V risks permanent damage, and operation above 30 V requires verification of thermal derating per the device's thermal metrics.
Does LM258PG4 support rail-to-rail input and output?
The LM258PG4 supports rail-to-rail input on the negative side - its common-mode input range includes V– (ground) - but does not offer full rail-to-rail output. Its output swings within 20 mV of V– and up to 1.5 V below V+ under 10 kΩ load. For true rail-to-rail I/O, consider TI's TLV2462 or similar modern alternatives; LM258PG4 remains appropriate for applications where only ground-sensing input is required.
Is LM258PG4 pin-compatible with LM358P?
Yes, LM258PG4 is pin-compatible with LM358P in the SOIC-8 package: both share identical pin functions (OUT1, IN1–, IN1+, V–, IN2+, IN2–, OUT2, V+) and mechanical footprint. However, LM258PG4 is characterized for –25°C to +85°C operation and has tighter 5 mV max input offset voltage versus 7 mV for LM358P, so direct substitution is electrically valid but may improve DC accuracy in temperature-variable environments.
What is the typical quiescent current of LM258PG4 per amplifier?
The LM258PG4 draws 350 µA typical quiescent current per amplifier at 25°C and 5 V supply, as documented in its Electrical Characteristics table. This value increases to ~600 µA at 30 V supply and remains within 460 µA maximum across the full –25°C to +85°C temperature range. This low IQ enables dual-channel amplification in battery-powered or energy-efficient designs without significant standby power penalty.
Can LM258PG4 drive capacitive loads directly?
The LM258PG4 is characterized to safely drive up to 100 pF capacitive load without oscillation, per its datasheet specification. Driving larger capacitive loads (e.g., long cables or ADC input capacitance >100 pF) requires isolation via a series resistor (typically 10–100 Ω) placed between the op amp output and the load to maintain phase margin and prevent instability. Layout best practices - including short traces and local bypassing - further ensure robust operation.
