Product details
Overview
LM358AD from Texas Instruments is a dual general-purpose operational amplifier in SOIC-8 package, designed for single-supply operation with rail-to-rail input (including ground) and 1.2MHz unity-gain bandwidth. It delivers 300µA/ch quiescent current, ±3mV max input offset voltage at 25°C, and operates across 3V–36V supply range - enabling use in power supply feedback, sensor signal conditioning, and motor control circuits.
For engineers reviewing the LM358AD datasheet, LM358AD pinout, LM358AD application, or LM358AD equivalent, this page provides verified electrical specifications, validated SOIC-8 pin functions, real-world application context for industrial power and motor systems, and two confirmed alternative parts with documented parameter and temperature-range differences.
Technical Context
The LM358AD belongs to the enhanced LM358B family, featuring internal RF/EMI filtering and unity-gain stability without external compensation. Its input stage supports common-mode voltage down to V– (ground in single-supply mode), enabling direct low-side current sensing and battery-voltage monitoring.
It uses bipolar input transistors with differential pair topology, delivering 70–140 V/mV open-loop gain and 0.5 V/µs slew rate. The output stage provides rail-swing capability: within 1.61V of V+ and 20mV of V– at 5mA load, supporting wide dynamic range in cost-sensitive analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3V to 36V - supports wide-input industrial power supplies and automotive battery monitoring without external regulators. |
| Unity-Gain Bandwidth | 1.2MHz - enables stable closed-loop operation up to ~100kHz with moderate gain, suitable for DC–audio-frequency signal conditioning. |
| Input Offset Voltage (max) | ±3mV at 25°C - ensures ≤3mV baseline error in precision DC amplification (e.g., thermistor or strain gauge interfaces). |
| Quiescent Current / Channel | 300µA typical - allows dual op-amp integration in battery-powered or energy-efficient systems without significant standby drain. |
| Common-Mode Input Range | Includes V– (ground) - permits direct sensing of signals referenced to system ground, eliminating level-shifting circuitry. |
| Output Swing (V– side) | 20mV above V– at 5mA load - supports accurate low-voltage signal reconstruction near ground in single-supply configurations. |
| ESD Rating (HBM) | ±2kV - meets IEC 61000-4-2 Level 2 robustness for industrial board-level ESD immunity without added protection. |
Pinout & Package
LM358AD is supplied in an 8-pin SOIC (D) package measuring 4.9mm × 6mm, with standard JEDEC outline and surface-mount compatibility.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives feedback networks or downstream stages; capable of sourcing/sinking ±20mA. |
| 2 | IN1− | Inverting input of Amp1 - accepts feedback or signal inversion paths; high-impedance (4GΩ||1.5pF). |
| 3 | IN1+ | Non-inverting input of Amp1 - used for reference, sensor, or signal injection; common-mode range includes ground. |
| 4 | V− | Negative supply or ground - serves as return path for both amplifiers; must be low-impedance for stability. |
| 5 | IN2+ | Non-inverting input of Amp2 - independent channel for parallel signal processing or dual-sensor interfaces. |
| 6 | IN2− | Inverting input of Amp2 - supports separate feedback loop; electrically isolated from Amp1 inputs. |
| 7 | OUT2 | Amplifier 2 output - fully independent output stage; shares same supply rails but no internal coupling. |
| 8 | V+ | Positive supply - powers both amplifiers; accepts up to 36V DC with thermal derating per RθJA = 124.7°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input (V− inclusive) | Enables direct interface with ground-referenced sensors (e.g., shunt current monitors) without level shifters. |
| Internal RF/EMI filter | Reduces susceptibility to conducted and radiated noise in noisy industrial environments like motor drives. |
| Unity-gain stable | Operates reliably with gain = 1 without external compensation, simplifying design of buffers and followers. |
| High CMRR (≥100 dB) | Rejects common-mode interference in differential measurements, improving accuracy in noisy PCB layouts. |
| Low quiescent current (300 µA/ch) | Supports always-on monitoring functions in energy-constrained applications such as smart HVAC controllers. |
Applications
| Power Supply Feedback | Motor Control Signal Conditioning |

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 and LM358B electrical specs; identical 1.2MHz GBW, ±3mV VOS, and 300µA IQ. | No functional difference; DR suffix denotes tape-and-reel packaging only - not a performance variant. | Select LM358DR for automated SMT assembly; LM358AD is tube-packaged and preferred for prototyping or low-volume builds. |
| LM2904DT | SOIC-8 variant with extended –40°C to +125°C operating range and ±2mV VOS (BA grade); otherwise identical architecture. | Required for under-hood automotive or outdoor industrial enclosures where ambient exceeds 85°C. | Choose LM2904DT when full automotive temperature range and tighter offset are mandatory; LM358AD suits commercial/industrial indoor use. |
Compared with LM358DR, LM358AD offers identical performance in tube packaging for manual placement, while LM2904DT provides superior temperature range and offset spec - making it the only drop-in upgrade for high-ambient designs requiring guaranteed 125°C operation.

FAQ
What is the maximum operating temperature range for the LM358AD?
The LM358AD is rated for operation from –40°C to +85°C ambient temperature. This range is confirmed in Section 5.3 (Recommended Operating Conditions) of the TI datasheet SLOS068AB, and applies specifically to the LM358AD variant - distinct from the LM2904BA (–40°C to +125°C) or LM358A (0°C to +70°C).
Does the LM358AD support true rail-to-rail output swing?
No, the LM358AD does not provide rail-to-rail output. Its output swings to within 1.61V of V+ and 20mV of V– at 5mA load (per Section 5.5 Electrical Characteristics). While the input includes the negative rail (V–), the output cannot reach either supply rail - a key distinction from modern rail-to-rail output op-amps.
Can the LM358AD be used in single-supply configurations?
Yes, the LM358AD is explicitly designed for single-supply operation. Its input common-mode range includes V– (ground), and its output can swing within 20mV of V–, allowing direct interfacing with ground-referenced sensors and microcontroller ADCs powered from the same rail.
What is the input bias current specification for the LM358AD?
The LM358AD exhibits a typical input bias current of –10nA and a maximum of –35nA at 25°C (Section 5.5, IB parameter), with –50nA maximum over the full –40°C to +85°C range. This bipolar-input characteristic requires careful attention to source impedance in high-precision applications.
Is the LM358AD pin-compatible with older LM358 variants?
Yes, the LM358AD maintains identical SOIC-8 pinout and electrical behavior with legacy LM358, LM358A, and LM358B devices. Pin functions (OUT1, IN1−, IN1+, V−, IN2+, IN2−, OUT2, V+) are standardized across all D-package versions, enabling drop-in replacement in existing designs.
