Product details
Overview
LM258APE4 from Texas Instruments is a dual operational amplifier in PDIP-8 package, designed for cost-sensitive industrial and consumer applications requiring rail-to-rail input (including ground) and stable operation from 3V to 30V supply. It delivers 0.7MHz gain-bandwidth product, 0.3V/µs slew rate, ±5mV max input offset voltage at 25°C, and 350µA typical quiescent current per channel - enabling precision sensing and signal conditioning in power supplies and motor control circuits.
For engineers reviewing the LM258APE4 datasheet, LM258APE4 pinout, LM258APE4 application, or LM258APE4 equivalent, this page provides verified electrical specifications, validated SOIC-8 and PDIP-8 pin mapping, real-world use cases in AC inverters and desktop PC power management, and two confirmed alternative parts with documented parameter and temperature-range differences.
Technical Context
The LM258APE4 belongs to the legacy LM258 family - a dual, internally compensated op amp optimized for single-supply operation with common-mode input range extending to ground. Its architecture supports unity-gain stability without external compensation and features high open-loop gain (≥25 V/mV) and robust output drive capability (±30mA short-circuit current).
Unlike the newer LM358B/LM2904B series, the LM258APE4 operates across –25°C to +85°C ambient temperature, uses older process technology with higher input offset drift (7 µV/°C), and lacks integrated RF/EMI filtering. Its 0.7MHz GBW and 0.3V/µs slew rate reflect design priorities for DC-coupled and low-frequency AC signal conditioning rather than high-speed response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3V to 30V - supports wide-input industrial power rails and battery-backed systems without level-shifting. |
| Gain-Bandwidth Product | 0.7 MHz - sufficient for closed-loop gain ≤100 at 7 kHz, suitable for sensor amplification and feedback loops in motor drives. |
| Input Offset Voltage (max) | ±5 mV at 25°C - defines worst-case DC error in precision DC-coupled stages; requires trimming or calibration in <1% accuracy designs. |
| Slew Rate | 0.3 V/µs - limits full-power bandwidth to ~48 kHz at 10V output swing; adequate for audio preamps and slow-control loops. |
| Quiescent Current (typ) | 350 µA per amplifier - enables low-power operation in always-on monitoring circuits without thermal derating concerns. |
| Common-Mode Input Range | Includes ground (V–) - allows direct interfacing with 0V-referenced sensors (e.g., current-sense shunts, thermistors) without biasing networks. |
| Output Current Drive | ±30 mA short-circuit - supports direct driving of LEDs, small relays, or ADC reference buffers without external transistors. |
Pinout & Package
LM258APE4 is supplied in an 8-pin Plastic Dual In-line Package (PDIP), measuring 9.81 mm × 9.43 mm. This through-hole package supports manual prototyping, wave soldering, and legacy board upgrades.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - capable of sourcing/sinking ±30 mA; swings within 1.5V of positive rail and 20mV of negative rail under load. |
| 2 | IN1– | Inverting input of Amp 1 - high-impedance node (input bias current ≤ –150 nA); sensitive to PCB leakage and EMI coupling. |
| 3 | IN1+ | Non-inverting input of Amp 1 - accepts signals down to ground; used for unity-gain buffers and differential front-ends. |
| 4 | V– | Negative supply or ground reference - must be low-impedance; shared return path for both amplifiers and load circuits. |
| 5 | IN2+ | Non-inverting input of Amp 2 - electrically isolated from Amp 1 inputs; enables independent dual-channel signal paths. |
| 6 | IN2– | Inverting input of Amp 2 - matches IN1– characteristics; supports matched feedback networks for consistent channel performance. |
| 7 | OUT2 | Amplifier 2 output - identical drive strength and voltage swing to OUT1; usable for dual-sensor conditioning or push-pull configurations. |
| 8 | V+ | Positive supply - accepts up to 30V; decoupling capacitor (0.1 µF ceramic) required within 1 cm for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input (to V–) | Enables direct connection to ground-referenced sources like shunt resistors or thermocouples without input biasing. |
| Unity-gain stable | Operates reliably with no external compensation in buffer, follower, or integrator configurations - reduces BOM count. |
| High open-loop gain (≥25 V/mV) | Ensures <0.1% closed-loop gain error at gains ≥10, critical for accurate voltage monitoring in PSU feedback networks. |
| Wide supply range (3V–30V) | Eliminates need for separate LDOs in mixed-voltage systems - powers directly from 5V, 12V, or 24V rails. |
| Industry-standard pinout | Drop-in compatible with LM358, LM2904, and LM158 families - simplifies redesign and second-source qualification. |
Applications
| AC Inverter Control | Desktop PC Power Management |

Use Value: Dual-channel integration replaces discrete transistor timing circuits; PDIP-8 allows hand-soldering during field repair of aging printer models. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358AP | Same PDIP-8 package; wider temp range (0°C to 70°C vs –25°C to 85°C); ±7mV max offset voltage (vs ±5mV). | Preferred for commercial-grade desktop peripherals where extended cold-start operation is not required. | Select LM358AP if ambient operating temperature stays above 0°C and higher offset tolerance is acceptable. |
| LM2904N | Same pinout; wider temp range (–40°C to 125°C); lower quiescent current (350µA typ vs 350µA typ); same 0.7MHz GBW. | Required for automotive cabin modules or industrial PLCs needing extended temperature qualification. | Choose LM2904N when operating below –25°C or above 85°C; verify layout compatibility with same PDIP-8 footprint. |
Compared with LM258APE4, LM358AP trades extended low-temperature operation for slightly higher offset voltage, while LM2904N adds automotive-grade thermal robustness without altering bandwidth or supply range - making it the preferred upgrade path for harsh-environment deployments.

FAQ
What is the maximum operating temperature for LM258APE4?
The LM258APE4 is rated for operation from –25°C to +85°C ambient temperature. This range is specified in Section 5.3 (Recommended Operating Conditions) of the TI datasheet SLOS068AB. Operation outside this range may cause parametric shift or functional failure. For applications requiring –40°C start-up, consider LM2904N as a validated alternative.
Does LM258APE4 support rail-to-rail output swing?
No, LM258APE4 does not provide rail-to-rail output. Its output swings to within 1.5V of the positive supply (V+) and 20mV of the negative supply (V–) under 10kΩ load. This limitation is documented in Section 5.10 Electrical Characteristics. For true rail-to-rail output, TI's TLV2372 or MCP6022 would be appropriate replacements.
Can LM258APE4 replace LM358 in existing designs?
Yes, LM258APE4 is pin-compatible and functionally interchangeable with LM358 in PDIP-8 packages. Both share identical pinout, supply range (3V–30V), gain-bandwidth (0.7MHz), and input/output characteristics. The LM258APE4 offers tighter input offset voltage (±5mV vs ±7mV max), making it a direct upgrade in noise-sensitive applications.
What is the input bias current specification for LM258APE4?
The LM258APE4 has a maximum input bias current of –150 nA at 25°C, with typical value of –20 nA. This is confirmed in Section 5.10 of the TI datasheet SLOS068AB. At –25°C to +85°C, the max increases to –300 nA. Designers should account for this current when using high-impedance feedback or sensor networks to avoid DC error accumulation.
Is LM258APE4 RoHS compliant and lead-free?
Yes, LM258APE4 is RoHS-compliant and lead-free. Per TI's packaging documentation (SLMA002), the "E4" suffix denotes lead-free, RoHS-compliant PDIP packaging with matte tin lead finish. No exemptions apply, and the device meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements.
