Product details
Overview
LM358DG4 from Texas Instruments is a dual general-purpose operational amplifier in SOIC-8 package, designed for single-supply or split-supply operation across 3V to 36V. It delivers 1.2MHz unity-gain bandwidth, 300µA/ch quiescent current, and rail-to-rail input common-mode range including ground-enabling direct low-side current sensing in power supply feedback loops.
For engineers reviewing the LM358DG4 datasheet, LM358DG4 pinout, LM358DG4 application, or LM358DG4 equivalent, this page provides verified electrical specs, validated SOIC-8 pin functions, real-world use cases in AC/DC converters and motor control, and two confirmed alternative parts with documented parameter differences.
Technical Context
The LM358DG4 implements a bipolar input stage with internal RF/EMI filtering, supporting stable operation in electrically noisy environments such as industrial motor drives and server PSU monitoring circuits. Its input stage allows common-mode voltage down to V– (ground in single-supply), and output swing reaches within 20mV of V– and 1.6V of V+ at 5mA load.
It features unity-gain stability without external compensation, 70–140 V/mV open-loop gain (typical), and 0.5 V/µs slew rate-making it suitable for DC-coupled signal conditioning, transducer amplification, and comparator applications where speed is secondary to precision and supply flexibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3V to 36V - supports wide-input industrial and automotive power rails without external regulators |
| Unity-Gain Bandwidth | 1.2 MHz - sufficient for closed-loop error amplification in switching PSUs up to ~200 kHz |
| Input Offset Voltage (max) | 3 mV at 25°C - enables accurate DC-level shifting and sensor signal amplification with ≤0.3% initial error |
| Quiescent Current per Channel | 300 µA - allows battery-backed or energy-sensitive designs with dual op-amp functionality |
| Common-Mode Input Range | Includes V– (ground) - permits direct sensing of shunt resistors tied to system ground |
| Output Swing (V– side) | 20 mV above V– at 5mA - supports low-voltage logic interfacing and rail-referenced comparators |
| ESD Rating (HBM) | 2 kV - meets basic handling robustness requirements for assembly and field deployment |
Pinout & Package
LM358DG4 is housed in an 8-pin SOIC (D) package measuring 4.9 mm × 6.0 mm, with standard JEDEC MS-012AC footprint and 1.27 mm pitch. Thermal resistance RθJA = 124.7°C/W enables operation up to +85°C ambient without forced airflow in typical PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Drives feedback network or next-stage input; capable of ±30 mA short-circuit current |
| 2 (IN1–) | Inverting input, Amp 1 | Accepts feedback signal or inverted input path; high common-mode rejection (≥100 dB) |
| 3 (IN1+) | Non-inverting input, Amp 1 | Receives reference or sensor signal; common-mode range extends to V– (ground) |
| 4 (V–) | Negative supply / ground | Reference node for both amplifiers; must be low-impedance for noise immunity |
| 5 (IN2+) | Non-inverting input, Amp 2 | Independent second channel input; identical electrical characteristics to Pin 3 |
| 6 (IN2–) | Inverting input, Amp 2 | Independent second channel inverting input; supports separate feedback configuration |
| 7 (OUT2) | Amplifier 2 output | Fully independent output; no crosstalk beyond specified 120 dB channel separation |
| 8 (V+) | Positive supply | Supports up to 36V; internal ESD protection clamps transients to safe levels |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input (V– inclusive) | Enables ground-referenced current sensing without level-shifting circuitry |
| Internal RF/EMI filtering | Reduces susceptibility to high-frequency noise in motor drive and SMPS environments |
| Unity-gain stable | Eliminates need for external compensation capacitors in voltage-follower or gain=1 configurations |
| Low quiescent current (300 µA/ch) | Permits dual-op-amp functionality in always-on subsystems with <1 mW total standby dissipation |
| High open-loop gain (70–140 V/mV) | Ensures <0.1% closed-loop gain error in precision buffer and instrumentation amplifier topologies |
Applications
| Power Supply Feedback Loop | Motor Current Sensing |
|---|---|
Use Scenario: Regulating output voltage in isolated flyback or forward converters using optocoupler-coupled feedback. IC Role / Device Role / Timing Role: Error amplifier comparing sensed output against reference; operates in DC-coupled mode with V– = GND. Use Value: Input offset ≤3 mV ensures <±0.5% regulation accuracy over temperature; rail-to-ground input allows direct connection to shunt resistor on low-side. | Use Scenario: Amplifying voltage across a 10 mΩ shunt in brushed DC motor H-bridge driver. IC Role / Device Role / Timing Role: Non-inverting amplifier with gain = 100, referenced to system ground. Use Value: Common-mode input range including V– eliminates need for expensive isolated amplifiers; 300 µA/ch current enables compact thermal design. |

IC Role / Device Role / Timing Role: Inverting amplifier with precision resistor network; operates from 5V single supply. Use Value: 1.2 MHz GBW supports fast step response to temperature changes; low input bias current (<35 nA) prevents thermistor loading errors. | Use Scenario: Amplifying 0–100 mV output from pressure transducer in factory automation PLC I/O module. IC Role / Device Role / Timing Role: Dual-channel signal conditioner: one amp for offset nulling, second for gain adjustment. Use Value: Dual configuration reduces component count vs discrete op-amps; SOIC-8 footprint simplifies layout and rework. |
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 SOIC-8 package, identical electrical specs (B-version), RoHS-compliant lead finish | No functional difference; DR is standard tape-and-reel variant with same performance and qualification | Select LM358DR for volume production requiring RoHS compliance and automated placement |
| LM2904DT | SOIC-8, wider temp range (–40°C to +125°C), higher ESD (2 kV HBM), but lower GBW (0.7 MHz) | Better suited for under-hood automotive or industrial enclosures; reduced bandwidth limits high-speed loop use | Choose LM2904DT when extended temperature operation is required and 0.7 MHz bandwidth suffices |
Compared with LM358DG4, LM358DR offers identical performance in a RoHS-compliant variant ideal for high-volume SMT lines, while LM2904DT trades bandwidth for extended temperature range and automotive-grade robustness-making it preferable for harsh-environment deployments where speed is not critical.

FAQ
What is the maximum supply voltage rating for LM358DG4?
The LM358DG4 supports a maximum supply voltage of 36 V across V+ and V– terminals. Absolute maximum ratings specify ±20 V differential or 40 V total, but recommended operating conditions limit continuous operation to 3 V–36 V. Exceeding 36 V risks permanent damage and violates TI's published specifications for this device.
Does LM358DG4 support rail-to-rail output swing?
No, LM358DG4 does not provide rail-to-rail output. Its output swings to within approximately 20 mV of V– and 1.6 V of V+ at 5 mA load. This limitation is inherent to its bipolar output stage and must be accounted for in low-voltage applications-e.g., a 5 V supply yields ~0.02 V to ~3.4 V usable output range.
Is LM358DG4 pin-compatible with LM358DR or LM358P?
Yes, LM358DG4 is pin-compatible with LM358DR (SOIC-8, RoHS) and LM358P (PDIP-8), sharing identical pinout and function mapping. However, LM358P uses a through-hole package and has different thermal and electrical characteristics (e.g., lower GBW, higher IQ), so electrical substitution requires validation in the target circuit.
What is the input offset voltage specification for LM358DG4 at full temperature range?
The LM358DG4 (B-version) specifies a maximum input offset voltage of ±4 mV over the full operating ambient temperature range of –40°C to +85°C. At 25°C only, the max is ±3 mV. This drift behavior is critical for precision DC-coupled applications and must be factored into system error budgets.
Can LM358DG4 be used as a comparator?
Yes, LM358DG4 can operate as an open-loop comparator, though not optimized for speed. With 0.5 V/µs slew rate and 10 µs overload recovery, it suits low-frequency threshold detection (e.g., battery low-voltage alarm). For high-speed or precision comparator use, dedicated devices like TLV3701 offer superior propagation delay and hysteresis control.
