Product details
Overview
LM358BAIPWR from Texas Instruments is a dual general-purpose operational amplifier in TSSOP-8 package, featuring 3V–36V wide supply range, 1.2MHz unity-gain bandwidth, 2mV max input offset voltage at 25°C, 300µA/ch quiescent current, and rail-to-rail input common-mode range including ground-enabling direct low-side current sensing in power supply feedback loops.
For engineers reviewing the LM358BAIPWR datasheet, LM358BAIPWR pinout, LM358BAIPWR application, or LM358BAIPWR equivalent, this device is selected for cost-sensitive industrial analog signal conditioning where precision, EMI resilience, and single-supply operation are required-particularly in motor control feedback, AC/DC converter voltage regulation, and sensor interface circuits.
Technical Context
The LM358BAIPWR implements two independent high-voltage op amps with internal RF/EMI filtering, unity-gain stable architecture, and input stage designed to accept common-mode voltages down to V– (ground in single-supply use). Its differential input voltage rating of ±32V supports robust operation in noisy environments.
It operates across –40°C to +85°C ambient temperature, delivers 0.5V/µs slew rate, achieves ≥70V/mV open-loop gain at 15V supply, and maintains 100pF capacitive load drive capability-making it suitable for closed-loop compensation networks without external isolation components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3V to 36V - supports single-supply 5V/12V/24V systems and dual-supply ±15V legacy designs without level-shifting. |
| Input Offset Voltage (max) | 2mV at 25°C - enables accurate DC-coupled amplification in 12-bit ADC front-ends with ≤0.5% full-scale error. |
| Unity-Gain Bandwidth | 1.2MHz - sufficient for loop compensation in switch-mode power supplies up to ~100kHz switching frequency. |
| Quiescent Current per Channel | 300µA typical - allows battery-powered or energy-harvesting applications to sustain >1-year runtime on coin-cell sources. |
| Common-Mode Input Range | Includes V– (ground) - permits direct sensing of shunt resistors placed on low-side return paths without level translation. |
| ESD Rating (HBM) | ±2000V - meets IEC 61000-4-2 Level 2 requirements for industrial board-level ESD immunity. |
| Output Swing (from rail) | 1.4V from V+ and 150mV from V– at 1mA - provides usable dynamic range in 3.3V/5V logic-compatible output stages. |
Pinout & Package
TSSOP-8 (PW) package: 3mm × 6.4mm body, 0.65mm pitch, surface-mount, moisture sensitivity level 1 (MSL1), RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Drives feedback network or next-stage input; capable of sourcing/sinking ±20mA into resistive loads. |
| 2 (IN1–) | Inverting input of Amp1 | Accepts feedback signal in transimpedance or inverting configurations; common-mode range extends to V–. |
| 3 (IN1+) | Non-inverting input of Amp1 | Receives reference or sensor signal; high common-mode rejection (>100dB) suppresses supply noise coupling. |
| 4 (V–) | Negative supply / ground | Reference node for single-supply operation; must be low-impedance to minimize PSRR degradation. |
| 5 (IN2+) | Non-inverting input of Amp2 | Independent channel for auxiliary functions (e.g., overvoltage comparator, bias generation). |
| 6 (IN2–) | Inverting input of Amp2 | Configurable as summing node or error amplifier input; shares same electrical specs as Pin2. |
| 7 (OUT2) | Amplifier 2 output | Provides second independent gain stage; electrically isolated from OUT1 except via shared supply rails. |
| 8 (V+) | Positive supply | Accepts up to 36V; internal EMI filter reduces conducted RF susceptibility above 30MHz. |
Key Features
| Feature | Design Value |
|---|---|
| Internal RF and EMI filter | Reduces susceptibility to 30–1000MHz radiated emissions, eliminating need for external ferrite beads in Class B industrial enclosures. |
| Rail-to-rail input common-mode range | Enables direct connection to ground-referenced current-sense resistors without external biasing networks. |
| Low quiescent current (300µA/ch) | Supports always-on monitoring in smart metering and IoT edge nodes with <10µA sleep-mode leakage budgets. |
| 2mV max input offset (BA version) | Improves accuracy in 12-bit data acquisition systems by reducing zero-error contribution below 0.05% FS. |
| High ESD tolerance (2kV HBM) | Eliminates requirement for external TVS diodes on op amp inputs in assembly-line handling and field service scenarios. |
Applications
| Power Supply Feedback | Motor Current Sensing |
|---|---|
|
Use Scenario: Regulating output voltage in 24V/48V AC-DC adapters using optocoupler-isolated feedback loop. IC Role / Device Role / Timing Role: Error amplifier comparing sensed output against reference; drives optocoupler LED with compensated loop response.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358BIPWR | 3mV max input offset (vs. 2mV), otherwise identical electrical specs and pinout. | Suitable where ±3mV offset is acceptable (e.g., non-precision voltage monitoring). | Select LM358BIPWR when cost optimization outweighs sub-mV offset requirement. |
| LM2904BAIPWR | Same 2mV offset, but rated for –40°C to +125°C operating range (vs. –40°C to +85°C). | Required for under-hood automotive or high-temp industrial environments. | Choose LM2904BAIPWR only if extended temperature qualification is mandatory. |
Compared with LM358BIPWR, LM358BAIPWR offers tighter offset for improved DC accuracy without layout or supply changes; versus LM2904BAIPWR, it trades extended temperature range for lower cost and identical performance within commercial-grade thermal limits.

FAQ
What is the maximum operating temperature for LM358BAIPWR?
The LM358BAIPWR is specified for operation from –40°C to +85°C ambient temperature. This range is validated per TI's production test conditions and applies to all electrical parameters in the datasheet unless otherwise noted. Operation beyond +85°C may cause parametric drift or reliability risk and is not guaranteed.
Does LM358BAIPWR support single-supply operation?
Yes, LM358BAIPWR supports true single-supply operation due to its input common-mode voltage range extending to V– (ground) and output swing within 150mV of V–. It functions reliably with 3V to 36V single-ended supplies, enabling direct interfacing with grounded sensors and microcontroller ADCs without level-shifting circuitry.
What is the input offset voltage specification for LM358BAIPWR?
The LM358BAIPWR has a maximum input offset voltage of 2mV at 25°C, with a worst-case limit of ±2.5mV over the full –40°C to +85°C operating range. This value is measured per TI's standard test conditions (VS = 5V–36V, RL = 10kΩ to VS/2) and is tighter than the 3mV spec of the LM358B variant.
Can LM358BAIPWR drive capacitive loads?
Yes, LM358BAIPWR is characterized to drive up to 100pF capacitive loads while maintaining stability. For loads exceeding 100pF, external series resistance (typically 10–100Ω) should be added at the output to isolate the capacitance and preserve phase margin, especially in unity-gain configurations.
Is LM358BAIPWR pin-compatible with other LM358 variants?
Yes, LM358BAIPWR uses the industry-standard TSSOP-8 (PW) package with identical pinout to LM358BIPWR, LM358IPWR, and LM2904BAIPWR. All share the same 1–8 pin mapping per Figure 4-1 in the datasheet, enabling direct PCB replacement within the same package footprint.
