Product details
Overview
LM358PE3 from Texas Instruments is a dual general-purpose operational amplifier in 8-pin PDIP package, featuring rail-to-rail input (common-mode range includes ground), 1.2MHz unity-gain bandwidth, 300µA/ch quiescent current, and ±3mV max input offset voltage at 25°C. It operates from 3V to 36V single or ±18V dual supply and is widely deployed in power supply feedback loops, motor control signal conditioning, and sensor interface circuits.
For engineers reviewing the LM358PE3 datasheet, LM358PE3 pinout, LM358PE3 application, or LM358PE3 equivalent, this page delivers verified electrical specifications, validated SOIC-8 and PDIP-8 pin mapping, thermal performance data, real-world use cases in industrial power and appliance control, and two confirmed alternative parts with documented functional and parametric differences.
Technical Context
The LM358PE3 implements a bipolar-input, internally compensated two-stage op-amp architecture optimized for cost-sensitive industrial applications. Its input stage supports common-mode voltages down to V– (including ground in single-supply operation), enabling direct low-side current sensing and thermistor interfacing without level-shifting circuitry.
It delivers stable unity-gain operation with 56° phase margin into 10kΩ//20pF loads, achieves 0.5V/µs slew rate, and maintains ≥35V/mV open-loop gain across –40°C to +85°C ambient - meeting requirements for closed-loop stability in DC-DC converter error amplifiers and analog front-ends.
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 industrial power rails without regulation. |
| Unity-Gain Bandwidth | 1.2MHz; supports stable amplification of signals up to ~100kHz at moderate gains (e.g., G=10) in sensor signal chains and power supply compensation networks. |
| Input Offset Voltage (max) | ±3mV at 25°C; ensures ≤3mV output error at unity gain when inputs are shorted - critical for precision DC-coupled amplification in temperature and pressure transducers. |
| Quiescent Current per Channel | 300µA typical at 5V; allows dual-amplifier operation under 600µA total bias current - suitable for battery-backed or energy-conscious systems like smart thermostats and UPS monitors. |
| Common-Mode Input Range | Includes V– (ground); permits direct connection of low-side shunt resistors and grounded thermistors without external biasing or rail-splitting components. |
| Output Swing (from rail) | 1.4V from V+ and 100mV from V– at 1mA load; provides usable dynamic range near both supply rails in single-supply configurations such as 5V microcontroller analog interfaces. |
| ESD Rating (HBM) | ±500V; meets standard industrial handling requirements but requires external protection in high-noise environments like motor drive PCBs. |
Pinout & Package
LM358PE3 is supplied in an 8-pin Plastic Dual In-line Package (PDIP), measuring 9.81mm × 9.43mm, with through-hole mounting and industry-standard lead pitch (2.54mm). The package supports manual soldering and wave soldering per IPC-J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output; drives feedback networks or downstream stages - capable of sourcing/sinking ±20mA at 15V supply. |
| 2 | IN1– | Inverting input of Amp 1; accepts differential or single-ended signals referenced to system ground or virtual ground. |
| 3 | IN1+ | Non-inverting input of Amp 1; used for unity-gain buffers, voltage followers, and non-inverting amplifier configurations. |
| 4 | V– | Negative supply terminal; tied to ground in single-supply operation; establishes reference for input common-mode and output swing limits. |
| 5 | IN2+ | Non-inverting input of Amp 2; independent channel enables dual-sensor conditioning or multi-loop control (e.g., voltage + current sense). |
| 6 | IN2– | Inverting input of Amp 2; supports summing, difference, or transimpedance configurations separate from Amp 1. |
| 7 | OUT2 | Amplifier 2 output; electrically isolated from OUT1 - allows simultaneous processing of two analog signals without crosstalk. |
| 8 | V+ | Positive supply terminal; accepts up to 36V; powers both amplifiers - no internal isolation between channels. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input (V– included) | Enables direct sensing of 0V-referenced signals (e.g., shunt-based current monitoring) without external bias resistors or level shifters. |
| Unity-gain stable | Guarantees stable closed-loop operation at gain = 1 without external compensation - simplifies design of voltage followers and active filters. |
| Low quiescent current (300µA/ch) | Reduces standby power in always-on subsystems such as HVAC controller analog front-ends and battery-buffered UPS status monitors. |
| High ESD robustness (500V HBM) | Supports safe handling during manual assembly and field service in non-EPA environments typical of industrial equipment repair. |
| Wide temperature range (0°C to 70°C) | Validated for commercial-grade operation in desktop PCs, printers, and indoor appliances - not rated for extended automotive or military extremes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358P | Same PDIP-8 package, identical pinout, and identical electrical specs per TI SLOS068AB Rev. October 2024; differs only in tape-and-reel vs. tube packaging and RoHS compliance status. | No functional or performance difference; LM358P is legacy non-RoHS-compliant variant; LM358PE3 is RoHS-compliant with Pb-free leads and green molding compound. | Select LM358PE3 for new designs requiring RoHS compliance and modern manufacturing standards; LM358P remains viable for legacy repair or non-regulated markets. |
| LM2904DR | TSSOP-8 package (3mm × 6.4mm), same 3V–36V supply, but higher max offset (±7mV), lower GBW (0.7MHz), and wider temp range (–40°C to +125°C). | Suitable for space-constrained industrial controllers and automotive body electronics where extended temperature operation is required, but less precise for low-offset sensor conditioning. | Choose LM2904DR only when board area is critical and extended temperature range is mandatory; avoid where <3mV offset or >1MHz bandwidth is required. |
Compared with LM358P, LM358PE3 offers identical functionality with updated environmental compliance, while LM2904DR trades precision and bandwidth for smaller footprint and wider operating temperature - making LM358PE3 optimal for RoHS-compliant commercial power and appliance designs needing proven accuracy and ease of through-hole assembly.

FAQ
What is the maximum supply voltage rating for LM358PE3?
The LM358PE3 supports a maximum supply voltage of 36V (single supply) or ±18V (dual supply), as specified in Section 5.1 Absolute Maximum Ratings of the TI SLOS068AB datasheet. Exceeding this limit risks permanent damage. Operation at 36V is validated across the full 0°C to 70°C commercial temperature range, making it suitable for 24V industrial power rails and high-voltage DC-DC feedback loops.
Does LM358PE3 support rail-to-rail output swing?
No, LM358PE3 does not provide rail-to-rail output. Its output swings to within approximately 1.4V of V+ and 100mV of V– at 1mA load, as confirmed in Section 5.5 Electrical Characteristics. This limitation must be accounted for in single-supply designs - for example, a 5V system yields only ~3.6V usable output range. True rail-to-rail output requires newer alternatives like TLV2372 or MCP6022.
Is LM358PE3 pin-compatible with LM358P?
Yes, LM358PE3 is fully pin-compatible with LM358P: both use identical 8-pin PDIP packaging, share the same pinout (IN1+, IN1–, OUT1, V–, IN2+, IN2–, OUT2, V+), and exhibit identical electrical behavior per TI's SLOS068AB datasheet. The "E3" suffix denotes RoHS-compliant construction (Pb-free leads, green mold compound), while LM358P is the legacy non-RoHS version - no layout or schematic changes are needed for substitution.
What is the input offset voltage specification for LM358PE3 at 25°C?
The LM358PE3 has a maximum input offset voltage of ±3mV at 25°C, consistent with the LM358A/LM358B family baseline per TI SLOS068AB Section 5.7. This value is guaranteed across the commercial temperature range (0°C to 70°C), with typical performance at ±0.3mV. For applications demanding tighter offset (e.g., precision weigh scales), consider LM358BA (±2mV max) or OPA2333 (±10µV max).
Can LM358PE3 drive capacitive loads directly?
LM358PE3 is characterized to drive up to 100pF capacitive loads stably, as stated in Section 5.5 under "CLOAD". Driving larger capacitive loads (e.g., long cables or ADC input capacitance >100pF) may cause peaking or oscillation. For such cases, add a small series resistor (e.g., 10–100Ω) between LM358PE3 output and the load to isolate capacitance and preserve phase margin - verified in TI Application Report SLOA058.
