Product details
Overview
LM358BAIDR from Texas Instruments is a dual general-purpose operational amplifier in SOIC-8 package, designed for cost-sensitive industrial and consumer applications. It delivers 1.2MHz unity-gain bandwidth, 2mV maximum input offset voltage at 25°C, 300µA per-channel quiescent current, and rail-to-rail input capability including ground-enabling direct low-side current sensing in power supply feedback loops.
For engineers reviewing the LM358BAIDR datasheet, LM358BAIDR pinout, LM358BAIDR application, or LM358BAIDR equivalent, this page provides verified electrical specifications, validated SOIC-8 pin functions, real-world use cases in motor control and AC inverters, and two confirmed alternative parts with documented parameter and temperature-range differences.
Technical Context
The LM358BAIDR implements two independent high-voltage op amps in a single monolithic IC, each featuring internally compensated unity-gain-stable architecture and common-mode input range extending to V– (ground in single-supply operation). Its bipolar input stage supports wide supply operation from 3V to 36V while maintaining stable DC performance across –40°C to +85°C ambient.
It integrates RF/EMI filtering on-chip and achieves 2kV HBM ESD robustness-critical for motor drive and industrial power electronics where noise immunity and ruggedness are mandatory. The device is not rail-to-rail output; output swing is specified as 1.5V from V+ and 20mV from V– under 5mA load at 5V supply.
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 external regulation. |
| Input Offset Voltage (max, 25°C) | ±2 mV - enables accurate low-level signal amplification (e.g., shunt-based current sensing) without trimming. |
| Unity-Gain Bandwidth | 1.2 MHz - sufficient for closed-loop response in power supply error amplifiers and sensor conditioning up to ~100 kHz. |
| Quiescent Current (per channel) | 300 µA typical - allows battery-backed or energy-efficient designs where standby power matters. |
| Common-Mode Input Range | Includes V– (ground) - permits direct interface with grounded sensors (e.g., thermistors, current shunts) in single-supply configurations. |
| ESD Rating (HBM) | ±2000 V - meets industrial IEC 61000-4-2 level 3 immunity requirements without external protection. |
| Operating Temperature | –40°C to +85°C - qualified for automotive under-hood ancillary circuits and industrial control cabinets. |
Pinout & Package
LM358BAIDR is supplied in an 8-pin SOIC (D) package measuring 4.9mm × 6mm, with standard JEDEC MS-012AC footprint and gull-wing leads compatible with automated SMT assembly.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives feedback networks or downstream stages; capable of sourcing/sinking ±20 mA. |
| 2 | IN1– | Inverting input of Amp 1 - connected to feedback resistor in standard inverting configuration or reference node in non-inverting setup. |
| 3 | IN1+ | Non-inverting input of Amp 1 - accepts sensor signals, reference voltages, or setpoints; CMVR includes ground. |
| 4 | V– | Negative supply or ground - serves as return path for both amplifiers; must be low-impedance for stability. |
| 5 | IN2+ | Non-inverting input of Amp 2 - used independently for second signal path (e.g., overvoltage comparator input). |
| 6 | IN2– | Inverting input of Amp 2 - configured for differential sensing or active filtering alongside IN2+. |
| 7 | OUT2 | Amplifier 2 output - isolated function from OUT1; shares same supply rails but no internal crosstalk beyond spec limits. |
| 8 | V+ | Positive supply - supplies both amplifiers; decoupling capacitor (0.1 µF ceramic) required within 1 cm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Internal RF/EMI filter | Reduces susceptibility to switching noise from nearby MOSFETs or PWM controllers in motor drives and SMPS. |
| Ground-sensing input stage | Enables single-supply operation with zero-input referenced transducers without level-shifting circuitry. |
| Low quiescent current (300 µA/ch) | Extends battery life in portable instrumentation and reduces thermal load in densely packed PCBs. |
| High open-loop gain (70 V/mV min) | Ensures <0.1% gain error in precision gain blocks using moderate feedback resistors (e.g., 10 kΩ–100 kΩ). |
| Capacitive load drive (100 pF) | Stably drives long traces or ADC input capacitors without external isolation resistors. |
Applications
| Power Supply Feedback Loop | Brushless DC Motor Phase Current Sensing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358BIDR | ±3mV max offset (vs. ±2mV), otherwise identical specs and SOIC-8 packaging. | Suitable where tighter offset is not required (e.g., non-critical signal conditioning). | Select LM358BIDR for cost-sensitive designs accepting 50% higher offset tolerance. |
| LM2904BAIDR | Same ±2mV offset and SOIC-8 package, but rated for –40°C to +125°C operating range. | Required for under-hood automotive modules or high-ambient industrial enclosures. | Choose LM2904BAIDR when extended temperature qualification is mandatory. |
Compared with LM358BAIDR, LM358BIDR trades offset precision for lower unit cost in commercial-temperature applications, while LM2904BAIDR maintains identical precision but extends thermal qualification to +125°C-making it suitable for harsher environments without layout changes.

FAQ
What is the maximum supply voltage rating for LM358BAIDR?
The LM358BAIDR supports a total supply voltage (V+ to V–) of up to 36V, with absolute maximum ratings specifying ±20V differential or 40V total. This allows operation from single 32V rails or dual ±18V supplies, making it compatible with legacy industrial 24V systems and modern high-voltage SMPS designs without external regulators.
Does LM358BAIDR support rail-to-rail input and output?
The LM358BAIDR features rail-to-rail input capability-its common-mode range includes V– (ground) and extends to within 1.5V of V+-but does not provide rail-to-rail output. Output swing is typically 1.5V from V+ and 20mV from V– under 5mA load at 5V supply, limiting dynamic range in low-voltage applications.
How does the input offset voltage of LM358BAIDR compare to LM358BIDR?
The LM358BAIDR guarantees a maximum input offset voltage of ±2mV at 25°C, whereas the LM358BIDR specifies ±3mV under identical conditions. This 33% tighter offset enables higher-accuracy signal conditioning in applications like precision current sensing or low-gain instrumentation amplifiers where offset directly impacts measurement fidelity.
Can LM358BAIDR drive capacitive loads without instability?
Yes-the LM358BAIDR is characterized to drive up to 100pF capacitive loads while maintaining phase margin ≥56°, enabling direct connection to ADC inputs, long PCB traces, or RC filters without series isolation resistors. For loads >100pF, external compensation or a small series resistor (10–50Ω) is recommended.
Is LM358BAIDR pin-compatible with older LM358 variants?
Yes-LM358BAIDR uses the standard SOIC-8 (D) package with identical pinout to LM358, LM358A, LM358B, and LM2904 series devices. No PCB redesign is needed when upgrading from LM358ADR or LM358BIDR, provided the system operates within the –40°C to +85°C ambient range and benefits from the improved 2mV offset specification.
