Product details
Overview
LM358APG4 from Texas Instruments is a dual general-purpose operational amplifier in 8-pin PDIP package, designed for cost-sensitive industrial and consumer applications. It delivers 0.7 MHz gain-bandwidth product, ±3 mV input offset voltage (max at 25°C), 350 µA typical quiescent current per channel, and rail-to-rail input common-mode range including ground - enabling single-supply sensor signal conditioning in power supplies, motor control feedback loops, and appliance control boards.
For engineers reviewing the LM358APG4 datasheet, LM358APG4 pinout, LM358APG4 application, or LM358APG4 equivalent, this page provides verified electrical specifications, validated SOIC-8-compatible pin functions, real-world use cases in AC inverters and multi-function printers, and two confirmed alternative parts with documented parameter and temperature-range differences.
Technical Context
The LM358APG4 belongs to the legacy LM358 family and shares its bipolar-input, internally compensated two-stage op-amp architecture. It operates from 3 V to 30 V supply (single or split), supports input voltages down to the negative rail, and features open-loop gain of 25–100 V/mV across 0°C to 70°C ambient.
Unlike the newer LM358B/BA variants, the LM358APG4 lacks integrated RF/EMI filtering and has higher input bias current (–20 to –250 nA) and lower ESD robustness (±500 V HBM). Its 0.3 V/mV CMRR and 0.7 MHz GBW reflect design priorities for stability and low-cost manufacturability over precision or high-speed performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 30 V - supports single-supply operation in 5 V and 24 V industrial systems without level-shifting circuitry |
| Input Offset Voltage (max) | ±3 mV at 25°C - limits DC accuracy in low-gain sensor amplifiers; requires calibration for sub-mV precision |
| Gain-Bandwidth Product | 0.7 MHz - suitable for audio preamps, slow-control loops, and DC-coupled signal conditioning up to ~100 kHz |
| Quiescent Current (typ) | 350 µA per amplifier - enables battery-powered or energy-conscious designs where ultra-low IQ is not required |
| Common-Mode Input Range | Includes V− (ground) - allows direct interfacing with grounded sensors (e.g., thermistors, current shunts) in single-supply configurations |
| Output Swing (min) | Within 1.5 V of positive rail and 20 mV of negative rail (at 5 V, RL ≥ 10 kΩ) - constrains headroom in rail-to-rail output applications |
| Operating Temperature | 0°C to +70°C - rated for commercial-grade environments; not qualified for automotive or extended industrial use |
Pinout & Package
LM358APG4 is supplied in an 8-pin Plastic Dual In-line Package (PDIP), measuring 9.81 mm × 9.43 mm, with through-hole mounting and standard lead spacing compatible with legacy PCB layouts and manual soldering processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Output of first amplifier - drives loads up to ±30 mA; limited swing near rails affects dynamic range in 5 V systems |
| 2 | IN1− | Inverting input of first amplifier - accepts signals referenced to ground or mid-supply; high impedance (≥2 MΩ) minimizes loading |
| 3 | IN1+ | Non-inverting input of first amplifier - used for unity-gain buffers or high-impedance sensing nodes |
| 4 | V− | Negative supply or ground reference - must be stable; shared return path impacts noise coupling between amplifiers |
| 5 | IN2+ | Non-inverting input of second amplifier - electrically isolated from IN1+ but shares same substrate; crosstalk < −120 dB |
| 6 | IN2− | Inverting input of second amplifier - identical electrical behavior to IN1−; supports independent second channel |
| 7 | OUT2 | Output of second amplifier - fully independent output stage; no internal connection to OUT1 |
| 8 | V+ | Positive supply - accepts up to 30 V; decoupling capacitor (0.1 µF) recommended at pin for stability |
Key Features
| Feature | Design Value |
|---|---|
| Unity-gain stable | Guarantees stable operation without external compensation in buffer, follower, or gain ≥ 1 configurations |
| Ground-sensing inputs | Enables direct interface with 0 V-referenced transducers (e.g., NTC thermistors, shunt resistors) in single-supply systems |
| Low input bias current | Typical −20 nA allows high-impedance source interfacing (e.g., pH electrodes, photodiodes with T-networks) |
| High open-loop gain | Minimum 25 V/mV ensures accurate closed-loop gain setting even with resistor tolerances up to ±1% |
| Robust short-circuit protection | Limits output current to ±40 mA during fault conditions, preventing thermal runaway in unregulated loads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DR | SOIC-8 package; identical electrical specs; same 0°C to +70°C temp grade; 350 µA IQ, 0.7 MHz GBW, ±3 mV VOS max | Suitable for surface-mount production; requires PCB redesign for footprint and reflow profile | Select LM358DR when automated assembly, smaller board area, or improved thermal resistance (RθJA = 124.7°C/W vs. 80.9°C/W for PDIP) are prioritized. |
| LM2904DR | Extended temp range (–40°C to +125°C); same 0.7 MHz GBW; ±3 mV VOS max; 350 µA IQ; higher input bias current (–20 to –150 nA) | Validated for automotive cabin modules and outdoor inverters requiring wider ambient tolerance | Choose LM2904DR when operation beyond 70°C ambient is required, especially in thermally constrained enclosures or under-hood locations. |
Compared with LM358APG4, LM358DR offers identical performance in a space-saving SOIC package ideal for modern SMT lines, while LM2904DR trades commercial temperature rating for industrial-grade reliability-making it preferable for harsh-environment deployments where thermal derating cannot be guaranteed.

FAQ
What is the maximum supply voltage for LM358APG4?
The LM358APG4 supports a maximum supply voltage of 30 V across V+ and V− terminals. This rating applies to both single-supply (e.g., 0 V and +30 V) and split-supply (e.g., ±15 V) configurations. Exceeding 30 V risks permanent damage, as specified in Absolute Maximum Ratings. Operation at 30 V is validated for output swing and quiescent current performance per TI's LM358A datasheet Section 5.7.
Does LM358APG4 support rail-to-rail input or output?
The LM358APG4 supports rail-to-rail input common-mode range - its inputs operate down to the V− rail (including ground) and up to V+ − 1.5 V. However, its output does not swing rail-to-rail: at 5 V supply and RL ≥ 10 kΩ, it reaches within 1.5 V of V+ and 20 mV of V−. Full rail-to-rail output requires newer alternatives like TLV2372 or LMV358.
What is the input offset voltage specification for LM358APG4?
The LM358APG4 has a maximum input offset voltage of ±3 mV at 25°C, with a worst-case value of ±9 mV across its full 0°C to +70°C operating temperature range. This parameter is measured under open-loop conditions with zero common-mode input voltage and is critical for DC-coupled applications such as precision sensor amplification or low-gain summing circuits.
Can LM358APG4 drive capacitive loads?
Yes, LM358APG4 can reliably drive capacitive loads up to 100 pF without instability, as confirmed in TI's LM358A datasheet Section 5.7. For larger loads (e.g., >200 pF), external isolation resistance (e.g., 100 Ω in series with the output) is recommended to maintain phase margin and prevent peaking or oscillation, particularly in unity-gain follower configurations.
Is LM358APG4 pin-compatible with other LM358 variants?
Yes, LM358APG4 is pin-compatible with all standard 8-pin LM358 family members in PDIP (P), SOIC (D), and TSSOP (PW) packages, including LM358, LM358A, LM358B, and LM2904. Pin functions - OUT1, IN1−, IN1+, V−, IN2+, IN2−, OUT2, V+ - match identically across these variants. Differences lie in electrical specs (e.g., offset, bandwidth, temp grade), not pinout or footprint.
