Product details
Overview
LM358BAIDDFR from Texas Instruments is a dual, high-voltage (3V–36V) operational amplifier in an 8-pin SOT-23 package, featuring 2mV max input offset voltage at 25°C, 1.2MHz unity-gain bandwidth, and 300µA/ch quiescent current. It enables ground-sensing single-supply operation and integrates RF/EMI filtering for robust performance in motor control feedback, power supply monitoring, and sensor signal conditioning.
For engineers reviewing the LM358BAIDDFR datasheet, LM358BAIDDFR pinout, LM358BAIDDFR application, or LM358BAIDDFR equivalent, this page delivers verified electrical specs, validated SOT-23-8 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 LM358BAIDDFR implements a bipolar-input, internally compensated two-stage op-amp architecture optimized for cost-sensitive industrial and consumer systems. Its rail-to-rail input stage includes common-mode voltage range extending to ground, while the output stage supports 1.5V swing from V– and 1.61V from V+ at 5mA load under 36V supply.
Designed for unity-gain stability with 56° phase margin and 0.5V/µs slew rate, it delivers 70–140 V/mV open-loop gain across –40°C to +85°C ambient, with 100pF capacitive load drive capability and 300Ω open-loop output resistance at 1MHz.

| 3 (IN1+) | Non-Inverting Input of Amplifier 1 | High-impedance node (4GΩ||1.5pF); used for reference biasing or positive feedback networks |
| 4 (V–) | Negative Supply / Ground | Reference terminal for single-supply operation; must be tied to system ground or lowest potential rail |
| 5 (IN2+) | Non-Inverting Input of Amplifier 2 | Independent high-Z input; supports separate sensor channel or reference path without crosstalk |
| 6 (IN2–) | Inverting Input of Amplifier 2 | Matches IN1– characteristics; enables dual-channel differential sensing or independent feedback paths |
| 7 (OUT2) | Output of Amplifier 2 | Electrically isolated from OUT1; supports concurrent signal processing (e.g., error amp + comparator buffer) |
| 8 (V+) | Positive Supply | Accepts up to 36V; internal protection limits absolute max to ±20V differential or 40V total supply range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358BIDDFR | 3mV max input offset (25°C), same 1.2MHz GBW and 300µA/ch IQ, identical DDF package | Lower DC precision; suitable where <1% error budget allows relaxed offset tolerance | Select when cost sensitivity outweighs need for sub-2mV offset in sensor front-ends |
| LM2904BAIDR | VSSOP-8 (DGK) package, 2mV max offset, but rated for –40°C to +125°C ambient | Broadened temperature range supports under-hood automotive or high-ambient industrial use | Choose for extended-temperature deployments where SOT-23 thermal dissipation may limit reliability |
Compared with LM358BAIDDFR, LM358BIDDFR trades 1mV offset tolerance for lower unit cost in commercial-temperature applications, while LM2904BAIDR provides identical DC performance with enhanced thermal resilience at the expense of larger footprint and higher junction-to-ambient thermal resistance (181.4°C/W vs. 164.3°C/W).

FAQ
What is the maximum supply voltage for LM358BAIDDFR?
The LM358BAIDDFR supports a maximum supply voltage of 36V across V+ and V– terminals, with absolute maximum ratings specifying ±20V differential or 40V total supply range. Operation beyond 36V risks permanent damage, and recommended conditions strictly cap VS at 36V for reliable long-term performance in industrial power supplies and motor control systems.
Does LM358BAIDDFR support single-supply operation with input signals at ground?
Yes, LM358BAIDDFR supports true single-supply operation with inputs referenced to ground: its common-mode input voltage range includes V– (ground), allowing direct connection of 0V-referenced sensors like current shunts or thermistors without level-shifting circuitry. This feature is explicitly validated across the full –40°C to +85°C operating range and is integral to its use in AC inverter current sensing and printer thermal monitoring.
How does the 2mV input offset voltage of LM358BAIDDFR impact precision applications?
The 2mV maximum input offset voltage at 25°C directly limits DC accuracy in closed-loop systems: for example, in a 100× gain current-sense amplifier using a 1mΩ shunt, this offset introduces up to ±200mA error at full scale. LM358BAIDDFR's offset remains ≤2.5mV over –40°C to +85°C, making it suitable for applications requiring <0.5% full-scale error where calibration or trimming is impractical.
Can LM358BAIDDFR drive capacitive loads, and what is the limit?
LM358BAIDDFR is characterized to drive up to 100pF capacitive loads while maintaining stability and specified phase margin (56°). Driving larger loads-such as long PCB traces or unbuffered ADC inputs-may cause ringing or oscillation; TI recommends adding a series resistor (typically 10–100Ω) between the output and capacitive node to isolate the load and preserve loop stability in motor control feedback paths.
What is the thermal performance of LM358BAIDDFR in the SOT-23-8 (DDF) package?
In the DDF package, LM358BAIDDFR has a junction-to-ambient thermal resistance (RθJA) of 164.3°C/W, meaning a 100mW internal power dissipation raises die temperature by ~16.4°C above ambient. With 300µA/ch quiescent current and typical output loading, power dissipation stays well below 50mW, ensuring safe operation up to +85°C ambient without heatsinking in properly ventilated enclosures.
