Product details
Overview
LM358BIPWR from Texas Instruments is a dual general-purpose operational amplifier in 8-pin TSSOP package, designed for cost-sensitive industrial and consumer applications. It operates from 3V to 36V supply, delivers 1.2MHz unity-gain bandwidth, draws only 300µA per channel quiescent current, and supports rail-to-rail input common-mode range down to ground - enabling direct low-side current sensing in power supplies and motor control circuits.
For engineers reviewing the LM358BIPWR datasheet, LM358BIPWR pinout, LM358BIPWR application, or LM358BIPWR equivalent, this page provides verified electrical specifications, validated pin functions, real-world use cases in AC inverters and multi-function printers, and two confirmed alternative parts with documented performance trade-offs.
Technical Context
The LM358BIPWR implements a bipolar-input, internally compensated voltage-feedback op amp architecture with dual independent amplifiers sharing a common supply. Its input stage includes integrated RF/EMI filtering and supports single-supply operation via ground-referenced common-mode input range (V– to V+ – 2V).
It features unity-gain stability, 3mV max input offset voltage at 25°C, and robust output drive capability (±20mA source/sink), making it suitable for transimpedance amplification, voltage buffering, and comparator-like threshold detection in rugged environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3V to 36V - enables direct integration into 5V, 12V, 24V, and 36V industrial power rails without level-shifting. |
| Unity-Gain Bandwidth | 1.2MHz - supports stable closed-loop operation up to ~100kHz with gain ≥10, sufficient for sensor signal conditioning and power supply error amplification. |
| Quiescent Current | 300µA per channel - reduces standby power in battery-backed or energy-conscious systems such as UPS and smart appliances. |
| Input Offset Voltage | ±3mV max at 25°C - ensures ≤3mV baseline error in precision DC-coupled gain stages (e.g., current-sense amplifiers with 50mV full-scale inputs). |
| Common-Mode Input Range | Includes ground (V–) - allows direct sensing of signals referenced to system ground, critical for low-side shunt monitoring in motor drivers and SMPS. |
| ESD Rating (HBM) | ±2000V - meets IEC 61000-4-2 Level 2 immunity requirements for board-level ESD robustness in factory automation equipment. |
| Operating Temperature | –40°C to +85°C - qualified for deployment in indoor/outdoor air conditioners, washing machines, and merchant server PSUs. |
Pinout & Package
LM358BIPWR is housed in an 8-pin TSSOP (PW) package measuring 3mm × 6.4mm, optimized for high-density PCB layouts while maintaining thermal performance (RθJA = 171.7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Output of Amplifier 1 | Provides buffered, low-impedance voltage output capable of sourcing/sinking ±20mA; connects directly to feedback networks or downstream analog stages. |
| 2 (IN1–) | Inverting Input of Amplifier 1 | Accepts differential input signals; used in inverting configurations, transimpedance amplifiers, or summing junctions with defined input impedance. |
| 3 (IN1+) | Non-inverting Input of Amplifier 1 | Supports ground-referenced inputs; enables non-inverting gain stages and comparator hysteresis networks with external resistors. |
| 4 (V–) | Negative Supply / Ground Reference | Serves as circuit common reference point; must be connected to lowest system potential (e.g., GND in single-supply designs). |
| 5 (IN2+) | Non-inverting Input of Amplifier 2 | Independent second channel input; allows simultaneous processing of two analog signals (e.g., voltage and current feedback in PSU control loops). |
| 6 (IN2–) | Inverting Input of Amplifier 2 | Enables dual-channel error amplification or independent sensor conditioning paths without cross-talk. |
| 7 (OUT2) | Output of Amplifier 2 | Electrically isolated output stage; drives separate loads or feeds into multiplexed ADC inputs in multi-sensor systems. |
| 8 (V+) | Positive Supply | Accepts up to 36V DC; powers both amplifiers; requires local 100nF ceramic decoupling adjacent to pin for stability under dynamic load conditions. |
Key Features
| Feature | Design Value |
|---|---|
| Internal RF/EMI Filter | Reduces susceptibility to conducted noise from switching regulators and motor drives, eliminating need for external ferrite beads in many industrial layouts. |
| Rail-to-Rail Input Common-Mode Range | Enables accurate amplification of signals near ground (e.g., 0–100mV shunt voltages), avoiding clipping in low-voltage sensing applications. |
| Unity-Gain Stable | Guarantees stable operation with no external compensation required, simplifying design of buffers, active filters, and gain-of-1 signal isolators. |
| High Output Drive Capability | ±20mA output current supports direct driving of LEDs, small relays, or 10kΩ load networks without external transistors. |
| Low Quiescent Current | 300µA/ch minimizes self-heating and extends battery life in always-on subsystems like HVAC thermostat front-ends or POS system status indicators. |
Applications
| AC Inverters | Multi-Function Printers |
|---|---|
|

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 (4.9mm × 6mm); same electrical specs but higher RθJA (124.7°C/W) and no integrated EMI filter. | Limited to lower-power or less electrically noisy environments (e.g., desktop peripherals vs. industrial motor drives). | Select when board space permits larger SOIC footprint and EMI immunity is not critical. |
| LM2904BIDR | Same PW package; extended temp range (–40°C to +125°C); identical 1.2MHz GBW and 300µA IQ, but 3mV offset applies up to +125°C. | Better suited for under-hood automotive modules or high-temp industrial enclosures where ambient exceeds +85°C. | Choose when operating ambient may exceed 85°C or when AEC-Q200 qualification is required. |
Compared with LM358DR, LM358BIPWR offers superior EMI resilience and smaller footprint; compared with LM2904BIDR, it trades extended temperature rating for lower cost and identical performance below +85°C - ideal for commercial-grade AC inverters and office equipment.

FAQ
What is the maximum supply voltage for LM358BIPWR?
The LM358BIPWR supports a maximum supply voltage of 36V across V+ and V– pins. This is specified as ±20V differential or 40V total, allowing direct use in 24V industrial systems and 36V battery-powered equipment without external regulation. Absolute maximum ratings prohibit exceeding 36V to avoid permanent damage.
Does LM358BIPWR support rail-to-rail output swing?
No, LM358BIPWR does not provide rail-to-rail output swing. Its output can swing to within ~1.4V of V+ and ~100mV of V– under light load (50µA), degrading to ~1.6V from V+ and ~1V from V– at 5mA load. For true rail-to-rail output, consider TI's TLV2462 or similar modern alternatives.
Can LM358BIPWR be used in single-supply configurations?
Yes, LM358BIPWR is explicitly designed for single-supply operation. Its input common-mode range includes the negative rail (V–), enabling direct connection to ground, and its output can drive loads referenced to ground. A typical configuration uses V– = GND, V+ = +5V to +36V, with input signals referenced to GND.
What is the input offset voltage specification for LM358BIPWR at full temperature range?
The LM358BIPWR has a maximum input offset voltage of ±4mV over its full operating ambient temperature range of –40°C to +85°C. At 25°C, the limit is tighter: ±3mV maximum. This is confirmed in Section 5.5 of the official datasheet (SLOS068AB) under "Electrical Characteristics: LM358B and LM358BA".
Is LM358BIPWR pin-compatible with legacy LM358 variants?
Yes, LM358BIPWR is pin-compatible with all standard 8-pin dual op amp footprints including SOIC-8 (D), TSSOP-8 (PW), VSSOP-8 (DGK), and SOT-23-8 (DDF). Pin numbering and function (OUT1, IN1–, IN1+, V–, IN2+, IN2–, OUT2, V+) match JEDEC-standard dual op amp layouts, enabling drop-in replacement in existing designs using compatible packages.
