Product details
Overview
LM358AP from Texas Instruments is a dual general-purpose operational amplifier in 8-pin PDIP package, designed for single-supply operation with rail-to-rail input (including ground) and output swing to within 1.5 V of positive rail. It delivers 0.7 MHz gain-bandwidth product, 0.3 V/µs slew rate, and 3 mV max input offset voltage at 25°C - enabling precision signal conditioning in cost-sensitive industrial power supplies and motor control feedback loops.
For engineers reviewing the LM358AP datasheet, LM358AP pinout, LM358AP application, or LM358AP equivalent, this page provides verified electrical specifications, validated SOIC/PDIP pin mapping, real-world use cases in AC inverters and point-of-sale systems, and two confirmed alternative parts with documented parameter differences.
Technical Context
The LM358AP belongs to the legacy LM358 family and shares its internal architecture: two independent high-voltage (3–30 V) op-amps with PNP input stages, enabling common-mode input down to ground. It uses bipolar process technology and lacks unity-gain stability enhancements found in newer B/BA variants.
Unlike LM358B/LM358BA, the LM358AP has no integrated RF/EMI filter, lower ESD rating (500 V HBM), and operates only from 0°C to +70°C ambient - making it suitable for commercial-grade applications where extended temperature or noise immunity is not required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 30 V - supports wide-input industrial power rails without external regulation |
| Gain-Bandwidth Product | 0.7 MHz - sufficient for DC–100 kHz signal conditioning in sensor interfaces and power supply error amplifiers |
| Slew Rate | 0.3 V/µs - limits large-signal response time; adequate for slow-varying control loops but not audio |
| Input Offset Voltage (max) | 3 mV at 25°C - introduces ≤3 mV error in unity-gain buffer; requires trimming for sub-mV accuracy |
| Common-Mode Input Range | Includes ground (V−) - enables direct sensing of 0 V-referenced signals like current-shunt voltages |
| Output Swing (positive rail) | Within 1.5 V at RL ≥ 10 kΩ - constrains headroom in low-voltage single-supply designs (e.g., 5 V systems) |
| Quiescent Current (per amp) | 350–600 µA - enables moderate battery life in always-on monitoring circuits |
Pinout & Package
LM358AP is supplied in 8-pin Plastic Dual In-line Package (PDIP), 9.81 mm × 9.43 mm footprint, through-hole mountable, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives loads up to ±30 mA; limited positive swing near V+ |
| 2 | IN1− | Inverting input of Amp1 - high-impedance node; sensitive to PCB leakage and EMI |
| 3 | IN1+ | Non-inverting input of Amp1 - accepts signals down to V− (ground), enabling single-supply biasing |
| 4 | V− | Negative supply or ground reference - must be low-impedance; shared return for both amps |
| 5 | IN2+ | Non-inverting input of Amp2 - electrically isolated from Amp1; same ground-referenced capability |
| 6 | IN2− | Inverting input of Amp2 - used for differential or inverting configurations with independent feedback |
| 7 | OUT2 | Amplifier 2 output - identical drive capability and swing limits as OUT1 |
| 8 | V+ | Positive supply - accepts up to 30 V; decoupling capacitor required near pin for stability |
Key Features
| Feature | Design Value |
|---|---|
| Ground-sensing input stage | Enables direct interface with 0 V–referenced current shunts or thermistor dividers without level-shifting |
| Single-supply operation | Eliminates need for split supplies in embedded controllers, reducing BOM count and layout complexity |
| High open-loop gain (25 V/mV) | Supports precise closed-loop gain accuracy in transducer signal conditioning and voltage regulation |
| Low input bias current (−20 to −250 nA) | Minimizes voltage error across high-value feedback resistors (>100 kΩ) in precision integrators |
| Robust short-circuit protection | Withstands indefinite output shorts to ground or V+ at TA ≤ 70°C, improving field reliability |
Applications
| AC Inverters | Point-of-Sale Systems |

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 and 0°C to +70°C rating; identical electrical specs per TI SLOS068AB Rev Oct 2024 Section 5.7 | No functional difference; LM358P is the base designation; LM358AP denotes A-grade (tighter 2–3 mV offset) | Select LM358AP when ≤3 mV offset is required at 25°C; otherwise LM358P offers same performance at lower cost |
| LM2904V | Wider temp range (−40°C to +125°C); higher ESD (500 V HBM); same 0.7 MHz GBW and 3 mV offset max | Required for automotive cabin modules or outdoor HVAC controls where extended temperature operation is mandatory | Choose LM2904V for new designs targeting industrial or automotive environments; LM358AP remains valid for commercial indoor equipment |
Compared with LM358P, the LM358AP guarantees tighter initial offset (2–3 mV vs. 3–7 mV), while LM2904V adds extended temperature support and robustness - making LM358AP optimal for cost-driven commercial applications where A-grade precision is needed without over-specifying.

FAQ
What is the maximum supply voltage for LM358AP?
The LM358AP supports a maximum supply voltage of 30 V (V+ − V−), as specified in Absolute Maximum Ratings (Section 5.1) and Recommended Operating Conditions (Section 5.3) of the TI SLOS068AB datasheet. Exceeding this may cause permanent damage. Operation at 30 V is validated for output swing and quiescent current performance across the 0°C to +70°C temperature range.
Does LM358AP support rail-to-rail input and output?
The LM358AP supports rail-to-rail input - its common-mode range includes V− (ground) and extends to V+ − 1.5 V - but does not support rail-to-rail output. The output swings to within ~1.5 V of V+ and ~20 mV above V− under light load (RL ≥ 10 kΩ), per Section 5.7 Electrical Characteristics. Full rail-to-rail output requires newer variants like LM358B.
What is the input offset voltage specification for LM358AP?
The LM358AP has a maximum input offset voltage of 3 mV at 25°C and 0°C to +70°C operating ambient, with typical value of 2 mV. This is tighter than the base LM358 (7 mV max) and aligns with the "A" grade defined in TI's SLOS068AB datasheet Section 5.7. Offset drift is 7 µV/°C over temperature.
Can LM358AP replace LM358 in existing designs?
Yes - the LM358AP is pin-compatible and electrically backward-compatible with LM358 in PDIP-8 packages. Its tighter offset (2–3 mV vs. 3–7 mV) and identical gain-bandwidth (0.7 MHz), slew rate (0.3 V/µs), and supply range (3–30 V) allow drop-in replacement where improved initial accuracy is beneficial without layout changes.
Is LM358AP suitable for automotive applications?
No - the LM358AP is rated for 0°C to +70°C ambient operation and lacks AEC-Q200 qualification. For automotive use, TI specifies LM2904V (−40°C to +125°C, qualified per AEC-Q100) or LM2904B (same temp range with enhanced EMI filtering). LM358AP is intended for commercial indoor equipment such as printers and HVAC indoor units.
