Product details
Overview
LM358APWR from Texas Instruments is a dual general-purpose operational amplifier in TSSOP-8 package, designed for single-supply or split-supply operation across 3V–30V. It delivers 0.7MHz gain-bandwidth product, 0.3V/µs slew rate, ±3mV max input offset voltage at 25°C, and rail-to-rail output swing near ground-enabling precision sensing in motor control feedback loops and power supply error amplifiers.
For engineers reviewing the LM358APWR datasheet, LM358APWR pinout, LM358APWR application, or LM358APWR equivalent, this page provides verified electrical specifications, validated pin functions, real-world use cases in industrial power systems, and two confirmed alternative parts with documented parameter and temperature-range differences.
Technical Context
The LM358APWR belongs to the legacy LM358 family with A-grade performance: it uses bipolar input stage architecture, supports common-mode input down to ground, and features internal frequency compensation for unity-gain stability. Its open-loop gain exceeds 25 V/mV and common-mode rejection reaches 65 dB over 0°C–70°C ambient range.
Unlike B/BA variants, the LM358A lacks EMI/RF filtering and has higher input offset drift (7 µV/°C) and lower ESD rating (500 V HBM). It is not rated for automotive or extended industrial temperature operation, distinguishing it from LM2904B or LM358B derivatives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3V to 30V - supports wide-input DC-DC converters and battery-powered systems without level-shifting. |
| Gain Bandwidth Product | 0.7 MHz - sufficient for closed-loop error amplification in 100 kHz switching power supplies. |
| Input Offset Voltage (max) | ±3 mV at 25°C - enables accurate low-side current sensing with <1% error at 100 mV sense voltage. |
| Slew Rate | 0.3 V/µs - limits large-signal response time to ~3.3 µs for 1 V step, suitable for non-audio signal conditioning. |
| Common-Mode Input Range | Includes ground - allows direct interface with 0 V-referenced sensors (e.g., thermistors, shunt resistors). |
| Output Swing (vs. V–) | 5–20 mV at 5 mA load - ensures usable headroom for single-supply comparator-like configurations. |
| Quiescent Current | 350–600 µA per amplifier - balances low-power operation with adequate drive capability for 2 kΩ loads. |
Pinout & Package
TSSOP-8 (PW) package: 3 mm × 6.4 mm body, 0.65 mm pitch, surface-mount, moisture-sensitive level 1 (MSL-1), RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Drives external load or feedback network; capable of sourcing/sinking ±20 mA. |
| 2 (IN1–) | Amplifier 1 inverting input | Accepts feedback signal or inverted input; high-impedance node (≤250 nA bias current). |
| 3 (IN1+) | Amplifier 1 non-inverting input | Receives reference or sensor signal; common-mode range extends to V– (ground). |
| 4 (V–) | Negative supply / ground | Reference for both amplifiers; must be stable and low-impedance for noise immunity. |
| 5 (IN2+) | Amplifier 2 non-inverting input | Independent input path; shares same supply rails and thermal environment as Channel 1. |
| 6 (IN2–) | Amplifier 2 inverting input | Used for differential or inverting configurations; channel separation >120 dB prevents crosstalk. |
| 7 (OUT2) | Amplifier 2 output | Electrically isolated output stage; drives separate load without affecting OUT1. |
| 8 (V+) | Positive supply | Single-ended or split-supply rail; decoupling capacitor required within 1 cm for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ground-sensing input stage | Enables direct connection to 0 V-referenced current shunts or thermistor dividers without level shifters. |
| Unity-gain stable architecture | Eliminates need for external compensation components in buffer, integrator, or follower designs. |
| High channel separation | 120 dB isolation prevents signal coupling between amplifiers in multi-channel feedback systems. |
| Robust output short-circuit protection | Withstands indefinite short to ground at TA ≤ 25°C and VS ≤ 15 V-critical for motor driver fault conditions. |
| Wide supply flexibility | Operates from 3 V (single-cell Li-ion) to 30 V (industrial 24 V bus), reducing BOM count across platforms. |
Applications
| Motor Control Feedback | Power Supply Error Amplifier |
|---|---|
Use Scenario: Closed-loop speed regulation in brushed DC motor drivers using back-EMF or hall-sensor signals. IC Role / Device Role / Timing Role: Dual op-amp implements PI controller (Channel 1) and current-limit comparator (Channel 2). Use Value: Ground-referenced inputs directly condition low-voltage sensor outputs; rail-swing capability maintains loop stability at low duty cycles. | Use Scenario: Voltage regulation in AC-DC adapters and DC-DC converters with optocoupler feedback. IC Role / Device Role / Timing Role: Error amplifier compares output voltage against reference and drives optocoupler LED. Use Value: 0.7 MHz GBW ensures phase margin >45° at 50 kHz loop frequencies; low quiescent current reduces no-load losses. |
| Industrial Sensor Signal Conditioning | Desktop PC Power Sequencing |
Use Scenario: Amplifying millivolt-level outputs from RTDs, thermocouples, or pressure bridges in HVAC controllers. IC Role / Device Role / Timing Role: First-stage instrumentation amplifier (gain = 100) and second-stage low-pass filter. Use Value: ±3 mV offset contributes <0.3% error at 1 V full-scale; common-mode range to ground avoids external biasing networks. | Use Scenario: Monitoring +12 V, +5 V, and +3.3 V rails during motherboard power-up and fault detection. IC Role / Device Role / Timing Role: Window comparator (two channels) detecting undervoltage/overvoltage thresholds. Use Value: Dual independent amplifiers enable simultaneous rail monitoring with shared reference; TSSOP-8 footprint saves PCB area vs. discrete solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358PWR | Same package, but standard grade: ±7 mV max offset, 0°C–70°C temp range, no guaranteed A-grade screening. | Lower accuracy; unsuitable for precision current sensing or extended-temp environments. | Select when cost sensitivity outweighs offset and temperature requirements. |
| LM2904DR | SOIC-8, −40°C to +125°C rating, ±7 mV offset, 0.7 MHz GBW, 500 V HBM ESD. | Broader operating temperature range supports automotive and outdoor industrial use. | Choose for extended ambient reliability where TSSOP-8 mounting is acceptable. |
Compared with LM358APWR, LM358PWR trades guaranteed offset performance for lower cost, while LM2904DR offers wider temperature tolerance at the expense of identical offset specs-making LM358APWR optimal for cost-constrained commercial equipment requiring A-grade precision at room temperature.

FAQ
What is the maximum operating temperature range for the LM358APWR?
The LM358APWR is specified for operation from 0°C to +70°C ambient temperature. This range is defined in Section 5.3 of the official datasheet and applies to all electrical characteristics unless otherwise noted. Operation outside this range may result in degraded offset voltage, gain, or output drive capability. For extended-temperature applications, consider LM358B or LM2904B variants.
Does the LM358APWR support rail-to-rail input or output?
The LM358APWR supports rail-to-rail input common-mode range down to V– (ground), but its output does not swing fully to either rail. At 5 mA load, the negative output swing is 5–20 mV above V–, and positive swing is typically 1.5–3 V below V+. This behavior is confirmed in Section 5.7 Electrical Characteristics. The LM358APWR is not a rail-to-rail output (RRO) device.
Can the LM358APWR be used in single-supply configurations?
Yes, the LM358APWR is explicitly designed for single-supply operation. Its input common-mode range includes ground (V–), and its output can swing close to V–, enabling direct interfacing with 0 V–referenced sensors and microcontroller ADCs. The datasheet recommends bypass capacitors and proper grounding practices to maintain stability in such configurations.
What is the typical quiescent current per amplifier in the LM358APWR?
The LM358APWR draws 350–600 µA per amplifier under recommended operating conditions (VO = 2.5 V, IO = 0 A, TA = 0°C to +70°C). At VS = 30 V, quiescent current increases to 500–1000 µA. These values are measured and published in Section 5.7 of the datasheet and reflect actual silicon behavior-not typical-only estimates.
Is the LM358APWR pin-compatible with other LM358-series devices in TSSOP-8?
Yes, the LM358APWR shares identical pinout and footprint with LM358PWR, LM358BTPWR, and LM358BATPWR in the PW (TSSOP-8) package. Pin functions-OUT1, IN1–, IN1+, V–, IN2+, IN2–, OUT2, V+-are consistent across all variants per Figure 4-1 and Table 4-1 of the datasheet. However, electrical performance (offset, bandwidth, temperature range) differs by grade.
