Product details
Overview
LM358ADGKR from Texas Instruments is a dual general-purpose operational amplifier in VSSOP-8 package, designed for cost-sensitive industrial and consumer applications. It delivers 3 mV max input offset voltage at 25°C, 1.2 MHz unity-gain bandwidth, 300 µA/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 LM358ADGKR datasheet, LM358ADGKR pinout, LM358ADGKR application, or LM358ADGKR equivalent, this page provides verified electrical specifications, validated VSSOP-8 pin mapping, real-world use cases in motor control and AC inverters, and two confirmed alternative parts with documented functional and thermal differences.
Technical Context
The LM358ADGKR belongs to the LM358B/BA family and implements a bipolar input stage with internal RF/EMI filtering, enabling stable operation in electrically noisy environments such as motor drives and power converters. Its input stage supports common-mode voltages down to V– (ground in single-supply mode), and its output can swing within 20 mV of V– and 1.61 V of V+ at 5 mA load.
It features unity-gain stability without external compensation, 56° phase margin at G = +1 with 10 kΩ//20 pF load, and 10 µs overload recovery time-making it suitable for closed-loop error amplification in DC-DC controllers and sensor signal conditioning where fast settling and robustness are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 3 V to 36 V - supports wide-input industrial power rails and battery-backed systems without level-shifting. |
| Input offset voltage (max, 25°C) | ±3 mV - enables accurate DC-coupled amplification in precision sensor interfaces and current-sense circuits. |
| Unity-gain bandwidth | 1.2 MHz - sufficient for 50–60 Hz line-frequency harmonics filtering and mid-speed control loop compensation. |
| Quiescent current per channel | 300 µA (typ) - allows dual op-amp integration in space-constrained, low-power designs like smart thermostats and IoT edge nodes. |
| Common-mode input range | Includes V– (ground) - permits direct sensing of shunt resistors referenced to system ground in high-side or low-side configurations. |
| ESD rating (HBM) | ±2000 V - meets IEC 61000-4-2 Level 2 requirements for board-level ESD immunity in commercial equipment. |
| Operating temperature | −40°C to +85°C - qualified for deployment in indoor/outdoor HVAC, printer engines, and industrial PLC I/O modules. |
Pinout & Package
DGK package: 8-pin Very Small Outline Package (VSSOP), 3 mm × 4.9 mm body, 0.5 mm pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Output of Amplifier 1 | Drives feedback networks or downstream comparators; capable of sourcing/sinking ±20 mA under specified conditions. |
| 2 (IN1–) | Inverting input of Amplifier 1 | Accepts differential or single-ended signals; common-mode range extends to V– for ground-referenced inputs. |
| 3 (IN1+) | Non-inverting input of Amplifier 1 | Used for reference biasing or positive feedback; matched impedance critical for CMRR optimization. |
| 4 (V–) | Negative supply / ground terminal | Reference node for both amplifiers; must be low-impedance to minimize noise coupling into input stage. |
| 5 (IN2+) | Non-inverting input of Amplifier 2 | Independent channel input; shares same V– and V+ rails but has separate input/output paths. |
| 6 (IN2–) | Inverting input of Amplifier 2 | Supports independent gain configuration; no internal cross-talk with Channel 1 per datasheet isolation specs. |
| 7 (OUT2) | Output of Amplifier 2 | Provides second analog path for dual-loop control (e.g., voltage + current regulation in SMPS). |
| 8 (V+) | Positive supply terminal | Supplies both amplifiers; decoupling capacitor (0.1 µF ceramic) required within 5 mm of this pin per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Internal RF and EMI filter | Reduces susceptibility to radiated emissions in motor drive PCBs and switch-mode power supplies. |
| Rail-to-rail input common-mode range | Enables direct interface with 0 V–referenced current-sense shunts without level-shifting circuitry. |
| Unity-gain stable architecture | Eliminates need for external compensation components in buffer, comparator, or integrator configurations. |
| Low quiescent current (300 µA/ch) | Permits dual op-amp use in always-on subsystems such as battery-backed real-time clocks or standby monitors. |
| High open-loop gain (70 V/mV min) | Ensures <1% gain error in closed-loop configurations with gains up to 100, even at temperature extremes. |
Applications
| Power Supply Feedback | Motor Current Sensing |
|---|---|
|
Use Scenario: Regulating output voltage in isolated flyback or forward DC-DC converters using optocoupler-coupled error amplification. IC Role / Device Role / Timing Role: Dual op-amp configured as error amplifier (Channel 1) and slope compensation generator (Channel 2).

IC Role / Device Role / Timing Role: Integrator-based timing generator (Channel 1), voltage supervisor (Channel 2) for rail validation. Use Value: Low 300 µA/ch quiescent current minimizes standby power draw; dual-channel integration reduces component count vs discrete solutions. |
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 | SOIC-8 package (4.9 mm × 6 mm); identical electrical specs but higher RθJA (124.7°C/W vs 181.4°C/W for DGK). | Preferred for through-hole prototyping or legacy board reuse; less suitable for thermally constrained VSSOP layouts. | Select LM358DR when board space allows larger footprint and thermal mass improves reliability in high-ambient environments. |
| LM2904DGKR | Same VSSOP-8 package; wider operating temperature (−40°C to +125°C) and lower input bias current (15 nA typ vs 10 nA typ for LM358A), but 0.7 MHz GBW. | Better suited for automotive cabin modules or industrial sensors requiring extended temp range; reduced bandwidth limits high-frequency loop response. | Choose LM2904DGKR only if −40°C to +125°C operation is mandatory and 0.7 MHz GBW suffices for control loop stability. |
Compared with LM358DR and LM2904DGKR, the LM358ADGKR offers optimal balance of compact VSSOP-8 size, 1.2 MHz bandwidth, and −40°C to +85°C qualification-making it ideal for space-limited commercial power electronics where thermal headroom and speed are prioritized over extended temperature range.

FAQ
What is the maximum supply voltage rating for LM358ADGKR?
The LM358ADGKR supports a supply voltage range of 3 V to 36 V (±2.5 V to ±18 V), with absolute maximum ratings of ±20 V or 40 V total across V+ and V– terminals. Operation beyond these limits risks permanent damage, and design margins should maintain at least 10% derating for long-term reliability in industrial environments.
Does LM358ADGKR support single-supply operation with input signals at ground potential?
Yes, the LM358ADGKR features a common-mode input voltage range that includes V– (ground in single-supply configurations), allowing direct connection of inverting or non-inverting inputs to 0 V references-critical for low-side current sensing and rail-to-rail signal conditioning without external level shifters.
What is the typical quiescent current per channel for LM358ADGKR at 5 V supply?
The LM358ADGKR draws 300 µA per amplifier at 5 V supply and 25°C, rising to 460 µA maximum across the full −40°C to +85°C operating range. This low IQ enables dual op-amp integration in battery-powered or energy-harvesting subsystems where standby power is tightly constrained.
Can LM358ADGKR drive capacitive loads, and what is the maximum stable value?
The LM358ADGKR is characterized to drive up to 100 pF capacitive loads while maintaining stability, as verified by phase margin testing at 56° with 10 kΩ//20 pF. For loads exceeding 100 pF, external series resistance (≥100 Ω) is recommended at the output to prevent peaking or oscillation in feedback paths.
Is LM358ADGKR pin-compatible with other LM358 variants in VSSOP-8 package?
Yes, LM358ADGKR shares identical pinout and footprint with LM358B, LM358BA, LM2904B, and LM2904BA in DGK (VSSOP-8) packaging-verified by TI's official pin function table and mechanical drawings. No PCB redesign is needed when migrating between these qualified variants.
