Product details
Overview
LM358DRG4 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 per amplifier quiescent current, ±3mV max input offset voltage at 25°C, 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 LM358DRG4 datasheet, LM358DRG4 pinout, LM358DRG4 application, or LM358DRG4 equivalent, this page provides verified pin functions, real-world use cases in motor control and AC inverters, key electrical specs per TI SLOS068AB (Oct 2024), and two validated alternative parts with documented parameter differences.
Technical Context
The LM358DRG4 implements a bipolar input stage with high differential input voltage capability (±32V) and internal RF/EMI filtering. Its architecture supports stable unity-gain operation without external compensation and enables direct sensing near ground due to VCM extending to V–.
It features open-loop gain of 70–140 V/mV, 0.5 V/µs slew rate, and 100 pF capacitive load drive capability-making it suitable for DC-coupled signal conditioning, transducer amplification, and voltage comparator circuits in industrial and consumer systems.
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 level-shifting. |
| Unity-Gain Bandwidth | 1.2 MHz - sufficient for audio preamps, sensor signal chains up to ~100 kHz, and slow-control loop compensation. |
| Input Offset Voltage (max) | ±3 mV at 25°C - enables accurate DC amplification in 8-bit ADC front-ends and current-sense applications with ≤0.5% error budget. |
| Quiescent Current | 300 µA per amplifier - allows dual op-amp integration in always-on monitoring circuits with sub-1 mA total supply draw. |
| Common-Mode Input Range | Includes ground (V–) - permits single-supply operation with inputs referenced to system ground, eliminating level-shifters in low-voltage sensing. |
| Output Swing (from rail) | 1.5 V from V+, 20 mV from V– at 5 mA - delivers usable dynamic range in 5V systems with rail-referenced loads. |
| ESD Rating (HBM) | 2 kV - meets basic handling requirements for assembly in non-classified environments without special ESD controls. |
Pinout & Package
LM358DRG4 is supplied in an 8-pin SOIC (D) package measuring 4.9 mm × 6.0 mm, with standard JEDEC MS-012AC footprint and gull-wing leads for automated PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives feedback networks, ADC inputs, or low-power actuators directly. |
| 2 | IN1− | Inverting input of Amp1 - connects to feedback resistor in inverting configurations or reference node in comparators. |
| 3 | IN1+ | Non-inverting input of Amp1 - accepts sensor signals, reference voltages, or buffered inputs requiring high-Z interface. |
| 4 | V− | Negative supply or ground - establishes lowest potential reference; supports true single-supply operation when tied to GND. |
| 5 | IN2+ | Non-inverting input of Amp2 - independent channel for parallel signal paths or dual-sensor conditioning. |
| 6 | IN2− | Inverting input of Amp2 - used for second feedback loop or differential pair configuration. |
| 7 | OUT2 | Amplifier 2 output - enables dual-channel functionality without external ICs, reducing BOM count in compact designs. |
| 8 | V+ | Positive supply - accepts up to 36V, enabling direct connection to unregulated 24V industrial rails or automotive battery inputs. |
Key Features
| Feature | Design Value |
|---|---|
| Internal RF and EMI filter | Reduces susceptibility to conducted noise in motor drive and switching power supply environments without external ferrites. |
| Rail-to-rail input common-mode range | Enables ground-referenced input stages in single-supply systems, eliminating need for biasing resistors or virtual grounds. |
| Unity-gain stable | Operates reliably with no external compensation in buffer, follower, or gain-of-one configurations-reducing layout complexity. |
| High differential input voltage (±32V) | Withstands transient overvoltage events across inputs during hot-plug or fault conditions without latch-up or damage. |
| Low quiescent current (300 µA/ch) | Supports dual-op-amp integration in battery-powered diagnostics modules where standby current must remain below 1 mA. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DT | Same SOIC-8 package; identical electrical specs per TI SLOS068AB; RoHS-compliant but not automotive-grade. | No extended temperature qualification (–40°C to 85°C only); lacks AEC-Q200 stress testing. | Select LM358DT for cost-sensitive commercial equipment where automotive reliability is not required. |
| LM2904DR | SOIC-8; same pinout; wider operating temp (–40°C to 125°C); higher ESD (2kV HBM); same 1.2 MHz GBW and 300 µA IQ. | Specified for under-hood automotive use; includes enhanced thermal robustness and qualification per AEC-Q100. | Choose LM2904DR when operating ambient exceeds 85°C or automotive qualification is mandatory. |
Compared with LM358DRG4, LM358DT offers identical performance at lower cost for non-automotive use, while LM2904DR extends temperature range and automotive compliance-making it preferable for engine control or EV charging modules where reliability under thermal stress is critical.

FAQ
What is the maximum supply voltage for LM358DRG4?
The absolute maximum supply voltage for LM358DRG4 is 40 V (±20 V), but the recommended operating range is 3 V to 36 V per TI SLOS068AB. Operation above 36 V risks exceeding safe junction temperature and degrading long-term reliability-even if within absolute ratings. LM358DRG4 maintains specified performance across its full 3–36 V range, making it ideal for 24V industrial rails and 36V battery systems.
Does LM358DRG4 support single-supply operation with inputs at ground?
Yes, LM358DRG4 supports true single-supply operation with inputs referenced to ground. Its common-mode input voltage range explicitly includes V– (ground when V– = 0 V), allowing direct connection of sensors or resistive dividers without level-shifting circuitry. This feature is confirmed in Section 5.3 (Recommended Operating Conditions) and Table 4-1 (Pin Functions) of the LM358DRG4 datasheet.
What is the input offset voltage specification for LM358DRG4 at 25°C?
The input offset voltage for LM358DRG4 is specified as ±3 mV maximum at 25°C, per TI's SLOS068AB datasheet (Section 5.5, Electrical Characteristics: LM358B and LM358BA). This value applies across the full 3–36 V supply range and is guaranteed-not typical-ensuring predictable DC accuracy in precision gain stages and comparator thresholds.
Can LM358DRG4 drive capacitive loads, and what is the limit?
LM358DRG4 is characterized to drive up to 100 pF capacitive loads without instability, as stated in Section 5.5 (Electrical Characteristics) of the TI datasheet. Driving larger capacitances-such as long cables or unbuffered ADC inputs-may cause peaking or oscillation. For >100 pF loads, a series resistor (e.g., 10–100 Ω) between LM358DRG4 output and the capacitor restores stability while preserving signal integrity.
Is LM358DRG4 pin-compatible with other dual op-amps in SOIC-8?
LM358DRG4 is pin-compatible with LM358, LM358A, LM2904, LM2904B, and LM2904BA in SOIC-8 (D) package, sharing identical pin 1–8 assignments per Figure 4-1 and Table 4-1 of the TI datasheet. However, electrical differences-including offset voltage, temperature range, and ESD rating-require validation for drop-in replacement. LM358DRG4 should not be substituted for LM258 or LM158 without verifying supply voltage and temp range compatibility.
