Product details
Overview
LM358ADRG4 from Texas Instruments is a dual general-purpose operational amplifier in SOIC-8 package, featuring rail-to-rail input (including ground), 36V max supply range, 1.2MHz unity-gain bandwidth, and 3mV max input offset voltage at 25°C. It serves as a cost-sensitive signal conditioning and amplification stage in power supply feedback loops, sensor interfaces, and motor control circuits.
For engineers reviewing the LM358ADRG4 datasheet, LM358ADRG4 pinout, LM358ADRG4 application, or LM358ADRG4 equivalent, this page delivers verified electrical specs, validated pin functions, real-world use cases in industrial power systems, and confirmed drop-in alternatives with documented performance trade-offs.
Technical Context
The LM358ADRG4 implements two independent high-voltage op-amps with common-mode input voltage range extending to V– (ground in single-supply operation), enabling direct sensing of low-side current shunts and thermistor bridges. Its internal EMI/RF filtering and 2kV HBM ESD rating support robust operation in electrically noisy environments like AC inverters and motor drives.
It operates across –40°C to +85°C ambient temperature, supports supply voltages from 3V to 36V, and delivers 0.5V/µs slew rate with 1.2MHz gain-bandwidth product-optimized for DC-coupled amplification, active filtering, and comparator applications where precision is secondary to reliability and wide supply tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3V to 36V - supports single-supply 5V/12V/24V systems and dual-supply ±15V rails without external regulation |
| Input Offset Voltage (max) | 3mV at 25°C - enables accurate DC amplification in 8-bit ADC front-ends with ≤0.5% error at 100mV input |
| Unity-Gain Bandwidth | 1.2MHz - sufficient for anti-aliasing filters up to ~100kHz and closed-loop gain ≥2 stability |
| Quiescent Current (per amp) | 300µA typical - allows battery-powered designs to sustain >1-year runtime on 200mAh coin cells with two active amps |
| Common-Mode Input Range | Includes V– (ground) - eliminates need for level-shifting circuitry when measuring signals referenced to system ground |
| Output Swing (from rail) | 1.4V from V+ and 100mV from V– at 50µA load - provides usable dynamic range in 3.3V/5V logic-compatible output stages |
| ESD Rating (HBM) | ±2000V - meets IEC 61000-4-2 Level 3 for handling in uncontrolled assembly environments |
Pinout & Package
LM358ADRG4 is packaged in an 8-pin SOIC (D package), 4.9mm × 6mm body size, with standard industry footprint and thermal characteristics (RθJA = 124.7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 3 (IN1+) | Non-inverting input of Amp 1 | Direct connection point for reference voltage or sensor outputs; supports rail-to-rail common-mode range |
| 4 (V–) | Negative supply / ground | Reference node for both amplifiers; must be low-impedance to minimize noise coupling |
| 5 (IN2+) | Non-inverting input of Amp 2 | Independent signal path for second channel; identical electrical behavior to Pin 3 |
| 6 (IN2–) | Inverting input of Amp 2 | Supports dual-channel configurations such as differential input + single-ended output |
| 7 (OUT2) | Amplifier 2 output | Electrically isolated from OUT1; enables independent gain/offset adjustment per channel |

FAQ
What is the maximum supply voltage for LM358ADRG4?
The LM358ADRG4 supports a maximum supply voltage of 36V across V+ and V– terminals. This rating applies to both single-supply (e.g., 0V to 36V) and dual-supply (e.g., ±18V) configurations. Exceeding 36V risks permanent damage, as specified in Absolute Maximum Ratings. The LM358ADRG4 maintains stable operation down to 3V, making it suitable for battery-backed and wide-input-range industrial power systems.
Does LM358ADRG4 support rail-to-rail input?
Yes, the LM358ADRG4 features rail-to-rail input capability that includes the negative supply rail (V–), allowing common-mode voltage down to ground in single-supply operation. This enables direct interfacing with ground-referenced sources like current-sense shunts and thermistors without external biasing networks. However, its output swing is not rail-to-rail-it typically reaches within 1.4V of V+ and 100mV of V– under light load.
What is the input offset voltage specification for LM358ADRG4?
The LM358ADRG4 has a maximum input offset voltage of ±3mV at 25°C, with a worst-case value of ±4mV over its full operating temperature range (–40°C to +85°C). This specification is confirmed in Section 5.5 of the official TI datasheet (SLOS068AB) for the LM358A variant. The offset voltage drift is ±3.5 µV/°C typical, supporting stable DC gain in temperature-varying environments.
Is LM358ADRG4 pin-compatible with LM358DR?
Yes, LM358ADRG4 is fully pin-compatible and footprint-compatible with LM358DR, sharing identical SOIC-8 pinout, electrical functionality, and thermal characteristics. The "A" suffix denotes improved initial offset voltage (3mV max vs. 7mV max for base LM358), and "G4" indicates RoHS-compliant, lead-free terminations with MSL 1 moisture sensitivity. No PCB layout changes are required when upgrading from LM358DR to LM358ADRG4.
What package type is used for LM358ADRG4?
The LM358ADRG4 uses the 8-pin SOIC (Small Outline Integrated Circuit) package, designated as "D" by Texas Instruments, with dimensions of 4.9mm × 6mm. This surface-mount package supports automated pick-and-place assembly and provides adequate thermal dissipation (RθJA = 124.7°C/W) for typical industrial ambient conditions up to +85°C.
