Product details
Overview
LM358DRG3 from Texas Instruments is a dual general-purpose operational amplifier in SOIC-8 package, designed for cost-sensitive industrial and consumer applications. It delivers 1.2MHz unity-gain bandwidth, 300µA per amplifier quiescent current, ±3mV max input offset voltage at 25°C, rail-to-rail output swing capability near ground, and operates from 3V to 36V single-supply or ±18V dual-supply - enabling use in power supply monitoring, motor control feedback, and sensor signal conditioning circuits.
For engineers reviewing the LM358DRG3 datasheet, LM358DRG3 pinout, LM358DRG3 application, or LM358DRG3 equivalent, this page provides verified electrical specifications, validated SOIC-8 pin functions, real-world implementation context for AC inverters and multi-function printers, and two confirmed alternative parts with documented parameter and temperature-range differences.
Technical Context
The LM358DRG3 implements a bipolar-input, internally compensated two-stage op-amp architecture optimized for stability at unity gain. Its input stage supports common-mode voltage down to ground (V–), enabling direct single-supply sensing of low-side current shunts or thermistor networks without level-shifting circuitry.
Each amplifier features independent biasing and output stages, with channel separation exceeding 120dB at 1kHz. The device includes integrated RF/EMI filtering and achieves 2kV HBM ESD robustness - critical for operation in electrically noisy environments like motor drives and industrial power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3V to 36V single-supply (±1.5V to ±18V dual); enables direct integration into 5V, 12V, 24V, and 36V systems without regulation. |
| Unity-Gain Bandwidth | 1.2MHz; supports stable closed-loop operation up to ~100kHz with moderate gain, suitable for DC–10kHz sensor amplification and power supply error amplifiers. |
| Input Offset Voltage (max) | ±3mV at 25°C; limits DC error in precision gain stages - e.g., introduces ≤30mV error in 10× amplification of 100mV sensor output. |
| Quiescent Current (per amp) | 300µA typical; allows dual-amplifier operation from microcontroller LDOs or battery-backed rails with minimal standby load. |
| Common-Mode Input Range | Includes ground (V–); permits direct connection of inverting inputs to ground-referenced sources such as shunt resistors or NTC thermistors. |
| Output Voltage Swing | Within 20mV of V– and 1.4V of V+ at 1mA load; supports rail-aware comparators and analog-to-digital interface buffering. |
| ESD Rating (HBM) | ±2000V; meets IEC 61000-4-2 Level 2 requirements for handling and board-level robustness in factory environments. |
Pinout & Package
LM358DRG3 is supplied in an 8-pin SOIC (D) package measuring 4.9mm × 6mm, with standard JEDEC MS-012AC footprint and gull-wing leads compatible with automated SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Drives external load or feedback network; capable of sourcing/sinking ±20mA. |
| 2 (IN1–) | Amplifier 1 inverting input | Accepts feedback or reference signals; high-impedance node requiring guard traces in high-precision layouts. |
| 3 (IN1+) | Amplifier 1 non-inverting input | Connects to sensor, reference, or signal source; supports common-mode range to V–. |
| 4 (V–) | Negative supply / ground | Reference for both amplifiers; must be low-impedance path to minimize noise coupling between channels. |
| 5 (IN2+) | Amplifier 2 non-inverting input | Independent input for second signal path; shares same V– and V+ rails as Amp1. |
| 6 (IN2–) | Amplifier 2 inverting input | Used for differential configuration or local feedback; isolated from Amp1 except via shared supply rails. |
| 7 (OUT2) | Amplifier 2 output | Provides second independent gain stage; channel separation >120dB prevents crosstalk in dual-sensor systems. |
| 8 (V+) | Positive supply | Power rail for both amplifiers; requires local 100nF ceramic decoupling adjacent to pin 8. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range (3V–36V) | Eliminates need for dedicated op-amp supply rails in mixed-voltage systems - e.g., interfaces 3.3V MCU ADC with 24V motor current sense. |
| Ground-sensing input stage | Enables true single-supply operation without external level shifters - critical for low-side shunt amplifier designs in UPS and inverter applications. |
| Integrated RF/EMI filter | Reduces susceptibility to switching noise from nearby MOSFET gate drivers or PWM controllers in motor control PCBs. |
| 2kV HBM ESD rating | Supports safe handling during manual assembly and field service without additional protection components on input/output lines. |
| Unity-gain stable | Guarantees stability with no external compensation required - simplifies design of voltage followers, active filters, and transimpedance 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 |
|---|---|---|---|
| LM358DT | Same SOIC-8 package; identical electrical specs (1.2MHz GBW, ±3mV VOS, 300µA IQ), but rated for 0°C to 70°C ambient (vs. –40°C to 85°C for LM358DRG3). | Limited to commercial-temperature applications (e.g., office printers, desktop peripherals); not qualified for industrial or outdoor equipment. | Select LM358DT only when full industrial temperature range is unnecessary and cost minimization is primary. |
| LM2904DR | SOIC-8 package; lower 0.7MHz GBW, higher ±7mV VOS (max), wider –40°C to 125°C operating range, and 350µA IQ (typ). | Better suited for high-temp automotive engine bay or industrial PLC modules where bandwidth demand is <100kHz and extended temperature is mandatory. | Choose LM2904DR when ambient exceeds 85°C or when lower bandwidth is acceptable - avoid for precision 100kHz+ signal paths. |
Compared with LM358DT and LM2904DR, the LM358DRG3 uniquely balances industrial temperature range (–40°C to 85°C), 1.2MHz bandwidth, and ±3mV offset in a cost-optimized SOIC-8 package - making it the preferred choice for AC inverters, server PSUs, and climate control systems requiring both performance and ruggedness.

FAQ
What is the maximum operating temperature range for the LM358DRG3?
The LM358DRG3 is specified for operation from –40°C to +85°C ambient temperature. This industrial-grade range is confirmed in Section 5.3 (Recommended Operating Conditions) of the TI datasheet SLOS068AB and distinguishes it from commercial variants like LM358DT (0°C to 70°C). Thermal derating is not required within this envelope when mounted on standard FR-4 with adequate copper pour.
Does the LM358DRG3 support rail-to-rail input or output?
The LM358DRG3 supports rail-to-rail output swing - delivering within 20mV of V– and 1.4V of V+ at 1mA load - but does not feature rail-to-rail input. Its input common-mode range extends to V– (ground) but only to (V+) – 1.5V at room temperature, per Section 5.5 Electrical Characteristics. This enables ground-referenced sensing but excludes full V+–referenced differential inputs.
Can the LM358DRG3 be used as a comparator?
Yes, the LM358DRG3 can be used as an open-loop comparator in non-critical applications due to its high open-loop gain (>70 V/mV) and rail-to-rail output. However, it lacks internal hysteresis and has slower response (10µs overload recovery) than purpose-built comparators. For reliable OVP/OCP in power supplies, external hysteresis resistors are recommended - as demonstrated in TI Application Report SLVA612.
What is the quiescent current consumption of the LM358DRG3 per amplifier?
The LM358DRG3 draws 300µA per amplifier typical at 5V supply and 25°C, rising to 460µA maximum across –40°C to +85°C. At 36V supply, quiescent current increases to 800µA maximum. These values are measured under no-load conditions and are critical for battery-powered or energy-harvesting designs where total system standby current must remain below 1mA.
Is the LM358DRG3 pin-compatible with older LM358 variants?
Yes, the LM358DRG3 is fully pin-compatible with all standard 8-pin LM358 family members in SOIC-8 (D) package, including LM358D, LM358DT, and LM358DR. Pin 1 (OUT1) through Pin 8 (V+) follow identical numbering and function mapping per Figure 4-1 and Table 4-1 of the TI datasheet - enabling drop-in replacement without PCB modification.
