Product details
Overview
LM258PE4 from Texas Instruments is a dual operational amplifier in 8-pin PDIP package, designed for cost-sensitive industrial and consumer applications requiring rail-to-rail input (common-mode down to ground) and stable operation from ±1.5V to ±15V supplies. It delivers 0.7MHz gain-bandwidth, 0.3V/µs slew rate, ≤5mV input offset voltage (max at 25°C), and 350µA typical quiescent current per channel - enabling low-power sensor signal conditioning in AC inverters and motor control feedback loops.
For engineers reviewing the LM258PE4 datasheet, LM258PE4 pinout, LM258PE4 application, or LM258PE4 equivalent, this page provides verified electrical specifications, SOIC/PDIP package mapping, functional pin definitions, real-world use cases in power supply monitoring and appliance motor drives, and two validated alternative parts with documented parameter differences.
Technical Context
The LM258PE4 implements a standard two-stage BJT-based op-amp architecture with internal frequency compensation for unity-gain stability. Its input stage supports common-mode voltages extending to the negative rail, allowing direct sensing of signals near ground without level-shifting circuitry.
It features open-loop gain ≥50 V/mV (min), CMRR ≥70 dB, PSRR ≥65 dB, and output swing within 20 mV of the negative rail and 1.5 V of the positive rail under 5 mA load - making it suitable for single-supply systems where headroom is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±1.5 V to ±15 V (3 V to 30 V total); enables flexible single- or dual-supply operation in battery-powered and line-powered equipment |
| Gain-Bandwidth Product | 0.7 MHz; supports stable closed-loop amplification up to ~10 kHz at gain = 70, sufficient for DC–audio-range signal conditioning |
| Input Offset Voltage (max) | 5 mV at 25°C (LM258A variant); sets minimum resolvable differential signal in precision comparator or transducer interfaces |
| Quiescent Current (typ) | 350 µA per amplifier; allows integration into always-on monitoring circuits with sub-mW power budgets |
| Common-Mode Input Range | Includes ground (V−); eliminates need for external biasing when amplifying unipolar sensor outputs (e.g., thermistors, current shunts) |
| Output Voltage Swing | Within 20 mV of V− and 1.5 V of V+ at 5 mA; supports high-side current sensing and analog front-end stages in 5 V microcontroller systems |
| Operating Temperature | –25°C to +85°C; qualified for indoor industrial environments including HVAC controllers and white goods |
Pinout & Package
LM258PE4 is housed in an 8-pin Plastic Dual In-line Package (PDIP), 9.81 mm × 9.43 mm footprint, through-hole mountable with 0.3 inch row spacing and 0.1 inch lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output; capable of sourcing/sinking ±20 mA, compatible with LED drivers or ADC reference buffers |
| 2 | IN1− | Inverting input of Amp 1; high-impedance node (≥2 GΩ common-mode) for precision feedback networks |
| 3 | IN1+ | Non-inverting input of Amp 1; accepts common-mode signals from V− to (V+) − 1.5 V |
| 4 | V− | Negative supply or ground reference; must be decoupled locally to minimize noise coupling between amplifiers |
| 5 | IN2+ | Non-inverting input of Amp 2; electrically isolated from Amp 1 inputs but shares same substrate |
| 6 | IN2− | Inverting input of Amp 2; used in differential-to-single-ended conversion or active filtering stages |
| 7 | OUT2 | Amplifier 2 output; independent channel for auxiliary functions like supply rail monitoring or error amplification |
| 8 | V+ | Positive supply; supports up to 30 V total supply range; requires 0.1 µF ceramic bypass capacitor to ground |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input (V− included) | Enables direct interface with grounded sensors (e.g., RTDs, shunt resistors) without external level-shift circuitry |
| Low input bias current (≤150 nA) | Minimizes voltage error in high-impedance source applications such as pH probes or photodiode transimpedance stages |
| High open-loop gain (≥50 V/mV) | Ensures <0.1% gain error in unity-gain buffer configurations across temperature and supply variations |
| Stable at unity gain | Eliminates need for external compensation components in voltage follower or active filter designs |
| ESD rating (HBM ±500 V) | Provides baseline handling robustness during PCB assembly and field service in non-aerospace industrial settings |

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 | Wider temp range (0°C to 70°C), higher max offset (7 mV), same 0.7 MHz GBW and PDIP-8 package | Approved for commercial-grade desktop PC power supplies; not rated for extended industrial ambient | Select LM358P only if operating temperature remains within 0–70°C and offset tolerance >5 mV is acceptable |
| LM2904DR | SOIC-8 package, extended temp range (–40°C to 125°C), lower max offset (7 mV), same 0.7 MHz GBW | Designed for automotive engine control modules; requires re-layout due to surface-mount footprint | Choose LM2904DR when board space is constrained and operation beyond 85°C is required |
Compared with LM358P and LM2904DR, the LM258PE4 offers the optimal balance of industrial temperature rating (–25°C to +85°C), PDIP-8 through-hole compatibility, and 5 mV offset performance - making it preferred for legacy-replacement and service-oriented industrial electronics where solderability and thermal margin are critical.

FAQ
What is the maximum supply voltage for LM258PE4?
The LM258PE4 supports a total supply voltage range of 3 V to 30 V (±1.5 V to ±15 V). Absolute maximum ratings specify ±16 V or 32 V, but recommended operation is limited to 30 V to ensure parametric compliance across temperature. Exceeding 30 V may degrade input offset drift and output swing performance, particularly at elevated ambient temperatures.
Does LM258PE4 support rail-to-rail output?
No, LM258PE4 does not provide rail-to-rail output. Its output swings to within 20 mV of the negative rail (V−) and 1.5 V of the positive rail (V+) under 5 mA load. This limitation is inherent to its BJT output stage and must be accounted for in design - for example, by selecting a 5 V supply when interfacing with a 3.3 V ADC reference to maintain adequate headroom.
Can LM258PE4 replace LM358 in existing designs?
Yes, LM258PE4 is pin-compatible and functionally equivalent to LM358P in PDIP-8 packaging, with identical pinout, electrical characteristics, and thermal behavior. Both share the same 0.7 MHz GBW, 0.3 V/µs slew rate, and 350 µA typical quiescent current. The LM258PE4 extends the operating temperature range to –25°C to +85°C versus LM358P's 0°C to 70°C, offering improved reliability in industrial environments.
What is the input offset voltage specification for LM258PE4?
The LM258PE4 (non-A suffix) has a maximum input offset voltage of 5 mV at 25°C, with a typical value of 3 mV. Over its full operating temperature range (–25°C to +85°C), the offset increases to ≤7 mV. This is confirmed in Section 5.10 of the TI SLOS068AB datasheet and distinguishes it from the tighter-tolerance LM258A variant (≤3 mV max at 25°C).
Is LM258PE4 suitable for single-supply operation?
Yes, LM258PE4 is explicitly designed for single-supply operation. Its input common-mode range includes the negative rail (ground), allowing direct amplification of unipolar signals such as those from current-sense shunts or temperature sensors. When operated from a single 5 V or 12 V rail, V− is connected to ground and V+ to the supply, with appropriate decoupling and output load considerations applied.
