Product details
Overview
LM358APWRG4 from Texas Instruments is a dual general-purpose operational amplifier in TSSOP-8 package, designed for cost-sensitive industrial and consumer applications. It delivers 3 mV max input offset voltage at 25°C, 1.2 MHz unity-gain bandwidth, and operates from 3 V to 36 V supply with rail-to-rail output swing near ground - enabling direct single-supply sensing in power supply feedback loops and motor control signal conditioning.
For engineers reviewing the LM358APWRG4 datasheet, LM358APWRG4 pinout, LM358APWRG4 application, or LM358APWRG4 equivalent, this page provides verified specifications, validated pin functions, real-world use cases in AC inverters and multi-function printers, and two confirmed alternative parts with documented parameter differences.
Technical Context
The LM358APWRG4 belongs to the LM358A variant family, featuring BJT-input stages with common-mode input range extending to ground and high differential input voltage capability (±32 V). Its internal architecture supports stable unity-gain operation without external compensation and includes integrated RF/EMI filtering for robustness in electrically noisy environments like motor drives and power supplies.
It is specified for 0°C to 70°C ambient operation, with quiescent current of 350 µA per amplifier (typical) and open-loop gain of 25–100 V/mV. The device uses standard dual op-amp topology with independent inputs and outputs, no internal phase inversion, and no shutdown or enable functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 30 V - supports single-supply operation in 5 V, 12 V, and 24 V systems without split rails. |
| Input Offset Voltage (max, 25°C) | 3 mV - enables accurate low-level signal amplification in sensor interfaces and current-sense circuits. |
| Unity-Gain Bandwidth | 0.7 MHz - sufficient for DC to ~100 kHz closed-loop applications including power supply error amplifiers. |
| Quiescent Current (per channel) | 350 µA (typ), ≤600 µA (max) - allows battery-powered or energy-efficient designs with minimal standby loss. |
| Common-Mode Input Range | Includes ground (V−) - permits direct sensing of signals referenced to system ground in single-supply configurations. |
| Output Voltage Swing | Within 1.5 V of positive rail and 20 mV of negative rail (at 5 V, RL ≥ 10 kΩ) - improves dynamic range in low-voltage applications. |
| ESD Rating (HBM) | ±500 V - meets basic industrial handling requirements but requires external protection in high-ESD environments. |
Pinout & Package
TSSOP-8 (PW) package: 3 mm × 6.4 mm body, 0.65 mm pitch, surface-mount, moisture sensitivity level 1 (MSL-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Drives feedback network or load; capable of sourcing/sinking ±20 mA (min) into resistive loads. |
| 2 (IN1−) | Amplifier 1 inverting input | Accepts feedback signal or inverted input; high-impedance node (input bias current ≤ −250 nA). |
| 3 (IN1+) | Amplifier 1 non-inverting input | Receives reference or sensor signal; common-mode range extends to V− (ground in single-supply). |
| 4 (V−) | Negative supply / ground | Reference for both amplifiers; must be connected even in single-supply use (0 V node). |
| 5 (IN2+) | Amplifier 2 non-inverting input | Independent input for second channel; identical electrical behavior to Pin 3. |
| 6 (IN2−) | Amplifier 2 inverting input | Independent input for second channel; used for summing, difference, or feedback configurations. |
| 7 (OUT2) | Amplifier 2 output | Second independent output; shares same drive strength and voltage swing limits as Pin 1. |
| 8 (V+) | Positive supply | Single positive rail (e.g., +5 V, +12 V, +24 V); powers both amplifiers simultaneously. |
Key Features
| Feature | Design Value |
|---|---|
| Ground-sensing input stage | Common-mode range includes V−, enabling direct interface with current-shunt resistors tied to ground. |
| Low input offset drift | 7 µV/°C typical - maintains accuracy across temperature in unregulated environments like HVAC controls. |
| High open-loop gain | 25–100 V/mV - ensures <0.1% gain error in closed-loop configurations with moderate feedback ratios. |
| Robust capacitive load drive | Stable with up to 100 pF load - simplifies PCB layout by tolerating trace capacitance and small bypass caps. |
| Channel separation | 120 dB - prevents crosstalk between dual channels in mixed-signal monitoring (e.g., voltage + current sense). |
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 |
|---|---|---|---|
| LM358BTPWR | Lower 3 mV offset (vs. 3 mV), 1.2 MHz GBW (vs. 0.7 MHz), −40°C to 85°C temp range (vs. 0°C to 70°C), 300 µA IQ (vs. 350 µA). | Supports wider industrial temperature range and higher bandwidth - suitable for automotive cabin modules or outdoor UPS units. | Select when extended temperature operation or faster settling (<4 µs) is required; verify PCB layout compatibility with same TSSOP-8 footprint. |
| LM2904DR | Same 3 mV offset, 0.7 MHz GBW, but −40°C to 125°C rating and SOIC-8 package (4.9 mm × 6 mm vs. 3 mm × 6.4 mm). | Preferred for high-reliability motor drives and industrial PLC I/O modules requiring extended temperature support. | Choose for legacy SOIC-compatible designs or where higher thermal mass improves long-term stability; larger footprint increases board area. |
Compared with LM358APWRG4, LM358BTPWR offers improved bandwidth and temperature range at identical pinout, while LM2904DR trades compact size for broader thermal capability and industry-standard SOIC packaging - both require no circuit redesign but differ in thermal performance and layout density.

FAQ
What is the maximum supply voltage for LM358APWRG4?
The LM358APWRG4 supports a maximum supply voltage of 30 V (V+ to V−), as specified in its Recommended Operating Conditions. This allows operation in 24 V industrial systems and high-voltage auxiliary rails without derating. Exceeding 30 V risks permanent damage, and absolute maximum rating is ±16 V or 32 V - not intended for continuous use.
Does LM358APWRG4 support rail-to-rail input or output?
The LM358APWRG4 supports rail-to-rail input common-mode range down to V− (ground), but not rail-to-rail output: its output swings within 1.5 V of V+ and as low as 20 mV above V− under light load. This makes it suitable for ground-referenced inputs but not for full 0–V+ signal swing without external level-shifting circuitry.
Can LM358APWRG4 replace LM358P in existing SOIC-8 designs?
No - LM358APWRG4 uses a TSSOP-8 package (3 mm × 6.4 mm, 0.65 mm pitch), while LM358P is in PDIP-8 (9.81 mm × 9.43 mm). Footprint, soldering process, and thermal characteristics differ significantly. Direct replacement requires PCB redesign; however, LM358ADR (SOIC-8) is a pin-compatible alternative with identical electrical specs.
What is the input bias current specification for LM358APWRG4?
The LM358APWRG4 has a typical input bias current of −20 nA and a maximum of −250 nA at 25°C, rising to −500 nA across its 0°C to 70°C operating range. This BJT-input characteristic necessitates low-impedance source impedances (<10 kΩ) in precision applications to avoid offset errors from bias current × source resistance.
Is LM358APWRG4 qualified for automotive applications?
No - LM358APWRG4 is rated for 0°C to 70°C ambient operation and lacks AEC-Q200 qualification. For automotive use, TI recommends LM2904BQDRQ1 (AEC-Q200 qualified, −40°C to 125°C) or LM358BQDRQ1, both offering enhanced ESD (±2000 V HBM) and tighter offset (2 mV max) in automotive-grade reliability screening.
