Product details
Overview
LM358PWRG4 from Texas Instruments is a dual general-purpose operational amplifier in an 8-pin TSSOP package, featuring rail-to-rail input (common-mode range includes ground), 1.2MHz unity-gain bandwidth, 300µA per amplifier quiescent current, and ±3mV maximum input offset voltage at 25°C - widely deployed in power supply feedback loops, motor control signal conditioning, and sensor interface circuits.
For engineers reviewing the LM358PWRG4 datasheet, LM358PWRG4 pinout, LM358PWRG4 application, or LM358PWRG4 equivalent, this page delivers verified electrical specifications, validated pin functions, real-world use cases in industrial and consumer power systems, and two technically documented alternative parts with explicit functional and thermal differences.
Technical Context
The LM358PWRG4 implements a bipolar-input, internally compensated two-amplifier architecture optimized for single-supply operation down to 3V, with input common-mode voltage extending to the negative rail - enabling direct low-side current sensing and ground-referenced transducer amplification without level-shifting circuitry.
It features unity-gain stable operation, 0.5V/µs slew rate, and integrated RF/EMI filtering to maintain signal integrity in electrically noisy environments such as AC inverters and motor drives, while its 2kV HBM ESD rating supports robust handling in automated assembly lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3V to 36V - supports wide-input industrial power rails and battery-backed systems without external regulation. |
| Unity-Gain Bandwidth | 1.2MHz - enables stable closed-loop gain up to 100kHz for anti-aliasing filters and medium-speed sensor signal conditioning. |
| Input Offset Voltage (max) | ±3mV at 25°C - ensures ≤30mV output error in unity-gain configurations with 10V output swing. |
| Quiescent Current | 300µA per amplifier - allows dual op-amp operation in always-on subsystems with sub-1mA total bias current. |
| Common-Mode Input Range | Includes ground (V−) - permits direct amplification of 0–2.5V thermistor or current-sense signals without input biasing. |
| Output Swing (vs. Rail) | Within 1.5V of V+ and 20mV of V− at 1mA load - provides usable dynamic range in 5V single-supply applications. |
| ESD Rating (HBM) | ±2000V - meets IEC 61000-4-2 Level 2 requirements for board-level ESD immunity in commercial equipment. |
Pinout & Package
LM358PWRG4 uses the PW (TSSOP-8) package: 3mm × 6.4mm body, 0.65mm pitch, exposed pad optional, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives feedback networks or downstream analog stages with 20mA sink/source capability. |
| 2 | IN1− | Inverting input of Amp1 - accepts feedback resistor for closed-loop gain configuration or differential input signals. |
| 3 | IN1+ | Non-inverting input of Amp1 - connects to reference voltage, sensor, or ground for comparator mode. |
| 4 | V− | Negative supply or ground - establishes reference for single-supply operation; must be low-impedance. |
| 5 | IN2+ | Non-inverting input of Amp2 - independent signal path for second channel; no internal coupling to Amp1. |
| 6 | IN2− | Inverting input of Amp2 - used for second feedback loop, summing junction, or active filter node. |
| 7 | OUT2 | Amplifier 2 output - electrically isolated from OUT1; shares same V+ and V− rails. |
| 8 | V+ | Positive supply - supplies both amplifiers; decoupling capacitor required within 1cm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input (V− included) | Enables direct amplification of ground-referenced signals like shunt-based current sensing without external bias resistors. |
| Internal RF/EMI filtering | Reduces susceptibility to high-frequency noise from switching power supplies and motor drivers without external ferrites. |
| Unity-gain stable | Eliminates need for external compensation components in buffer, follower, or gain-of-1 configurations. |
| Low quiescent current (300µA/ch) | Supports dual-op-amp functionality in battery-powered or energy-harvesting nodes with minimal standby drain. |
| High open-loop gain (70V/mV) | Ensures <0.1% gain error in precision gain stages using standard 1% feedback resistors. |
Applications
| Power Supply Feedback | Motor Control Signal Conditioning |
|---|---|

Use Value: Dual-channel integration reduces PCB area vs discrete solutions; TSSOP-8 footprint supports high-density industrial PCB layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DR | Same electrical specs; SOIC-8 package (4.9mm × 6mm), higher thermal resistance (RθJA = 124.7°C/W vs 171.7°C/W for TSSOP). | Preferred for through-hole prototyping or legacy board compatibility; less suitable for space-constrained motor control modules. | Select LM358DR when board layout requires SOIC footprint or thermal mass improves stability under sustained 36V operation. |
| LM2904DR | Identical pinout and function; wider operating temperature (–40°C to +125°C vs –40°C to +85°C); same 300µA IQ but 0.7MHz GBW (vs 1.2MHz). | Better suited for under-hood automotive or high-ambient industrial enclosures; lower bandwidth limits use in >50kHz feedback loops. | Choose LM2904DR for extended-temperature deployments where 0.7MHz bandwidth suffices and thermal derating is critical. |
Compared with LM358DR and LM2904DR, the LM358PWRG4 offers optimal balance of bandwidth, low-power operation, and compact TSSOP packaging for cost-sensitive industrial power and motor control designs - delivering 1.2MHz performance in a 3×6.4mm footprint without sacrificing reliability or manufacturability.

FAQ
What is the maximum supply voltage for LM358PWRG4?
The LM358PWRG4 supports a maximum supply voltage of 36V across V+ and V− terminals, with absolute maximum ratings specifying ±20V differential or 40V total. This allows direct use in 24V industrial bus systems and 36V battery-powered equipment without external regulators or voltage dividers.
Does LM358PWRG4 support single-supply operation?
Yes, LM358PWRG4 fully supports single-supply operation: its input common-mode voltage range extends to the negative rail (V−), and output can swing within 20mV of V− at light loads. This enables ground-referenced sensor interfaces and rail-to-rail input amplification in 5V or 12V-only systems without dual-rail supplies.
What is the input offset voltage specification for LM358PWRG4 at room temperature?
The LM358PWRG4 has a maximum input offset voltage of ±3mV at 25°C, consistent with the LM358B variant per TI's SLOS068AB datasheet. This value is guaranteed over the full operating temperature range (–40°C to +85°C), with typical offset at 0.3mV - critical for precision DC-coupled gain stages.
Can LM358PWRG4 drive capacitive loads directly?
LM358PWRG4 is characterized to drive up to 100pF capacitive loads stably, as confirmed in Section 5.5 of the official datasheet. For larger loads (e.g., long cables or ADC input capacitance), external series resistance (10–100Ω) is recommended to prevent peaking or oscillation due to phase margin reduction.
Is LM358PWRG4 pin-compatible with other LM358 variants?
Yes, LM358PWRG4 is pin-compatible with all standard 8-pin dual op-amps in the LM358 family (including LM358DR, LM358DGKR, LM2904DR), sharing identical TSSOP-8 pinout per Figure 4-1 and Table 4-1 of the TI datasheet - enabling drop-in replacement in existing designs using compatible packages.
