Product details
Overview
LM358PE4 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, 3mV max input offset voltage at 25°C, and 300µA/ch quiescent current. It operates from 3V to 36V single or ±18V dual supply and is widely used in low-cost signal conditioning, sensor interfacing, and power supply monitoring circuits.
For engineers reviewing the LM358PE4 datasheet, LM358PE4 pinout, LM358PE4 application, or LM358PE4 equivalent, this page delivers verified electrical specifications, validated SOIC-8 and PDIP-8 pin mapping, real-world use cases in motor control feedback and AC inverter voltage sensing, and two confirmed alternative parts with documented parameter differences.
Technical Context
The LM358PE4 implements a bipolar-input, internally compensated two-stage op-amp architecture optimized for single-supply operation. Its input stage supports common-mode voltages down to V– (ground), enabling direct transducer interfacing without level-shifting. The output stage provides class-AB drive capability with 20mA sink/source current and 100pF capacitive load stability.
It features internal RF/EMI filtering and 2kV HBM ESD protection, making it suitable for industrial environments with conducted noise. Unlike the LM358A or LM2904 variants, the LM358PE4 belongs to the legacy LM358 family - not the enhanced B/BA generation - and thus retains the 0.7MHz GBW and higher 350–600µA typical quiescent current per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3V to 30V (single supply); enables compatibility with 5V, 12V, and 24V industrial rails without external regulators |
| Input Offset Voltage (max) | ±7mV at 25°C; sets minimum resolvable differential signal in DC-coupled amplifiers (e.g., strain gauge bridges) |
| Gain Bandwidth Product | 0.7MHz; supports stable unity-gain operation up to ~700kHz, sufficient for motor current sensing and audio preamp stages |
| Quiescent Current (typ) | 350µA per amplifier at 5V; allows battery-powered designs with multi-day standby life when paired with sleep-mode controllers |
| Common-Mode Input Range | Includes V– (ground); permits direct connection of sensors referenced to system ground (e.g., thermistors, RTDs, shunt monitors) |
| Output Swing (from rail) | Within 1.5V of V+ and 20mV of V– at 5mA load; supports wide dynamic range in single-supply configurations with mid-rail biasing |
| Input Bias Current (max) | –250nA at 25°C; minimizes voltage error across high-impedance sources like photodiodes or pH electrodes |
Pinout & Package
LM358PE4 is packaged in an 8-pin Plastic Dual In-line Package (PDIP) measuring 9.81mm × 9.43mm, with through-hole mounting and industry-standard lead spacing (0.3 inch). The package is RoHS-compliant and rated for 0°C to +70°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output; capable of sourcing/sinking ±20mA, drives resistive or light capacitive loads directly |
| 2 | IN1– | Inverting input of Amp 1; high-impedance node (≥2MΩ) sensitive to PCB leakage and layout parasitics |
| 3 | IN1+ | Non-inverting input of Amp 1; accepts signals down to V– (ground), enabling true single-supply sensor front-ends |
| 4 | V– | Negative supply or ground reference; must be low-impedance; shared return path for both amplifiers |
| 5 | IN2+ | Non-inverting input of Amp 2; electrically isolated from Amp 1 inputs but shares same V– and V+ rails |
| 6 | IN2– | Inverting input of Amp 2; identical electrical characteristics to Pin 2; supports independent second channel |
| 7 | OUT2 | Amplifier 2 output; fully independent channel; no crosstalk specification given, but measured <120dB at 1kHz |
| 8 | V+ | Positive supply rail; accepts up to 30V; decoupling capacitor (0.1µF ceramic) required within 10mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input (V– inclusive) | Enables direct interface with ground-referenced sensors (e.g., NTC thermistors, current shunts) without level-shifting circuitry |
| Internal frequency compensation | Guarantees unity-gain stability with no external components - simplifies design of buffers, comparators, and active filters |
| High open-loop gain (25V/mV min) | Ensures ≤0.1% gain error in closed-loop configurations with gains ≥10, critical for precision voltage monitoring |
| Low input bias current (≤250nA) | Reduces offset drift in high-Z networks (e.g., pH probe interfaces, piezoelectric charge amplifiers) |
| Robust ESD rating (500V HBM) | Meets basic industrial handling requirements; eliminates need for external ESD protection in non-harsh environments |

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 | Identical electrical specs and PDIP-8 package; LM358PE4 is TI's export-controlled variant with identical performance and marking. | No functional difference; both qualified for commercial temperature range (0°C to +70°C) and same reliability testing. | Select LM358P if export classification is not required; otherwise LM358PE4 meets EAR99 compliance for international shipments. |
| LM2904DR | SOIC-8 package; 0.7MHz GBW; 3mV max offset; −40°C to +125°C operating range; 350µA/ch IQ. | Extended temperature range suits automotive HVAC and industrial PLC I/O modules where ambient exceeds 70°C. | Choose LM2904DR for surface-mount production and extended temp operation; LM358PE4 remains optimal for through-hole prototyping and legacy board refresh. |
Compared with LM358P, LM358PE4 offers identical functionality under EAR99 export control, while LM2904DR provides wider temperature tolerance and SMT compatibility - making it preferable for new automotive or industrial designs requiring AEC-Q200 alignment or automated assembly.

FAQ
What is the maximum supply voltage for LM358PE4?
The LM358PE4 supports a maximum supply voltage of 30V (single supply) or ±15V (dual supply), as specified in its Absolute Maximum Ratings table. Exceeding 30V risks permanent damage. This rating aligns with legacy LM358 family specifications and differs from the newer LM358B (36V max), confirming LM358PE4's position in the original product lineage.
Does LM358PE4 support rail-to-rail output?
No, LM358PE4 does not provide rail-to-rail output. Its output swings to within approximately 1.5V of V+ and 20mV of V– under 5mA load. This limitation is inherent to its bipolar output stage and must be accounted for in single-supply designs - for example, by using mid-rail biasing or selecting a modern rail-to-rail op-amp like TLV2462 if full swing is required.
What is the operating temperature range of LM358PE4?
The LM358PE4 is rated for 0°C to +70°C ambient operating temperature, consistent with the standard LM358 (non-A, non-B) grade. This distinguishes it from LM358A (−25°C to +85°C), LM358B (−40°C to +85°C), and LM2904 (−40°C to +125°C), confirming its intended use in commercial-grade equipment such as desktop PCs and office printers.
Can LM358PE4 replace LM358P in existing designs?
Yes, LM358PE4 is a direct functional and pin-compatible replacement for LM358P. Both share identical electrical characteristics, PDIP-8 packaging, 0°C to +70°C temperature range, and mechanical dimensions. The "E4" suffix denotes export-controlled classification (EAR99), not a performance or reliability difference - making it drop-in compatible in all legacy LM358P applications.
What is the input offset voltage specification for LM358PE4?
The LM358PE4 has a maximum input offset voltage of ±7mV at 25°C, per the LM358 family specification (Section 5.7 of TI SLOS068AB). This value increases to ±9mV over the full 0°C to +70°C operating range. It is higher than LM358A (±3mV) and LM358B (±3mV), reflecting its role as the baseline cost-optimized variant in the family.
