Product details
Overview
LM358DE4 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 input offset voltage (max at 25°C), and rail-to-rail input common-mode range including ground - enabling single-supply sensor signal conditioning in power supplies, motor control feedback, and AC inverter voltage sensing.
For engineers reviewing the LM358DE4 datasheet, LM358DE4 pinout, LM358DE4 application, or LM358DE4 equivalent, this page provides verified electrical specifications, SOIC-8 terminal mapping, real-world use cases in desktop PC power management and motor control, and two validated alternative parts with documented parameter and temperature-range differences.
Technical Context
The LM358DE4 implements a bipolar-input, internally compensated two-stage op-amp architecture optimized for stability at unity gain. Its input stage supports common-mode voltages down to V– (ground in single-supply operation), while output swing reaches within 1.4V of V+ and 150mV of V– at 1mA load - critical for low-voltage sensing near reference rails.
It features integrated RF/EMI filtering and 2kV HBM ESD protection, making it suitable for electrically noisy environments like motor drive PCBs and AC inverter control boards. The device operates across –40°C to +85°C ambient, matching industrial-grade thermal requirements without derating.
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 external regulators. |
| Unity-Gain Bandwidth | 1.2MHz - enables stable closed-loop operation up to ~100kHz with moderate gain, sufficient for DC-DC error amplifiers and motor current loop filters. |
| Input Offset Voltage (max) | ±3mV at 25°C - ensures ≤3mV baseline error in precision voltage monitoring (e.g., 12V supply sense with 0.1% accuracy target). |
| Quiescent Current | 300µA per amplifier - allows dual-op-amp implementation in always-on subsystems with sub-1mA total bias current. |
| Common-Mode Input Range | Includes V– (ground) - permits direct interfacing with grounded sensors (e.g., shunt resistors, thermistors) in single-supply configurations. |
| Output Voltage Swing | Within 1.42V of V+, within 150mV of V– at 1mA - delivers usable dynamic range in 5V or 12V single-rail systems without level-shifting circuitry. |
| ESD Rating (HBM) | ±2000V - meets IEC 61000-4-2 Level 2 immunity requirements for board-level robustness in factory automation equipment. |
Pinout & Package
LM358DE4 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) 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 feedback networks or downstream comparators; capable of sourcing/sinking ±20mA. |
| 2 | IN1– | Inverting input of Amp1 - connects to feedback resistor or summing node; high-impedance (≥10MΩ) bipolar input. |
| 3 | IN1+ | Non-inverting input of Amp1 - interfaces with sensors or reference dividers; common-mode range extends to V–. |
| 4 | V– | Negative supply or ground - serves as return path for both amplifiers; must be low-impedance for noise rejection. |
| 5 | IN2+ | Non-inverting input of Amp2 - independent channel for parallel signal paths (e.g., voltage + current sensing in PSU). |
| 6 | IN2– | Inverting input of Amp2 - used for differential measurement or transimpedance configuration with photodiodes. |
| 7 | OUT2 | Amplifier 2 output - isolated signal path; shares same supply rails but no internal crosstalk beyond specified 120dB channel separation. |
| 8 | V+ | Positive supply - accepts up to 36V; decoupling capacitor (0.1µF ceramic) required within 5mm for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input (V– inclusive) | Enables direct connection to grounded shunt resistors or thermistors without level-shifting components in 5V/12V systems. |
| 1.2MHz GBW with unity-gain stability | Eliminates need for external compensation in voltage follower or non-inverting amplifier configurations up to 100kHz. |
| 300µA per amplifier quiescent current | Reduces total bias consumption to <600µA for dual-channel operation - critical for battery-powered diagnostics modules. |
| Integrated RF/EMI filter | Suppresses high-frequency noise coupling from switching power stages (e.g., PWM inverters), improving signal integrity without added ferrites. |
| 2kV HBM ESD protection | Meets industrial handling requirements without external TVS diodes on op-amp inputs in motor control interface circuits. |
Applications
| Power Supply Feedback Loop | Motor Current Sensing |

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, identical electrical specs (±3mV VOS, 1.2MHz GBW, 300µA IQ), but rated for 0°C to 70°C ambient - not qualified for extended industrial temperature range. | Limited to commercial-grade applications (e.g., consumer printers, basic chargers); unsuitable for outdoor HVAC or factory-floor motor controllers. | Select LM358DR only when operating ambient stays within 0–70°C and cost is primary constraint. |
| LM2904DT | SOIC-8 variant with wider operating temperature (–40°C to +125°C), same 1.2MHz GBW and 300µA IQ, but ±3mV VOS max applies only at –40°C to +125°C (vs. 25°C for LM358DE4). | Better suited for under-hood automotive or high-temp industrial enclosures where full-range offset spec matters. | Choose LM2904DT when ambient exceeds 85°C or when AEC-Q200 qualification is required; verify offset drift over full range. |
Compared with LM358DR and LM2904DT, the LM358DE4 offers guaranteed ±3mV input offset at 25°C and –40°C to +85°C operation - making it optimal for industrial power supplies and motor drives where mid-range precision and thermal margin are balanced without automotive overhead.

FAQ
What is the maximum supply voltage rating for LM358DE4?
The LM358DE4 supports a total supply voltage (V+ to V–) of up to 36V, with absolute maximum ratings specifying ±20V differential or 40V total. This allows direct use in 24V industrial systems and 36V battery-powered equipment without external regulators or voltage clamping.
Does LM358DE4 support single-supply operation with input referenced to ground?
Yes, LM358DE4 features a common-mode input voltage range that includes the negative supply rail (V–), enabling true single-supply operation with grounded inputs - essential for interfacing with shunt-based current sensors or thermistors tied to system ground in 5V or 12V applications.
What is the typical output voltage swing of LM358DE4 at 1mA load?
At 1mA load, LM358DE4 delivers an output swing within 1.4V of V+ and within 150mV of V–. For example, with V+ = 12V and V– = 0V, the output can reach 10.6V high and 150mV low - providing >10V usable range for analog signal processing in standard logic-supply systems.
How does the ESD protection of LM358DE4 compare to legacy LM358 variants?
LM358DE4 provides ±2000V Human-Body Model (HBM) ESD protection, significantly exceeding the ±500V rating of older LM358 and LM358A versions. This enhanced robustness eliminates need for external ESD diodes in motor control and power supply designs exposed to handling or field transients.
Is LM358DE4 pin-compatible with other dual op-amps in SOIC-8 package?
Yes, LM358DE4 uses the industry-standard SOIC-8 pinout defined in TI's SLOS068AB datasheet: Pin 1=OUT1, Pin 2=IN1–, Pin 3=IN1+, Pin 4=V–, Pin 5=IN2+, Pin 6=IN2–, Pin 7=OUT2, Pin 8=V+. This matches LM358DR, LM2904DT, and most generic dual op-amps in D/SOIC-8, enabling drop-in replacement where electrical specs align.
