Texas Instruments LM358BIDDFR

Overview

LM358BIDDFR from Texas Instruments is a dual general-purpose operational amplifier in an 8-pin SOT-23 package, featuring rail-to-rail input (including ground), 1.2MHz unity-gain bandwidth, 300µA per amplifier quiescent current, and ±3mV max input offset voltage at 25°C. It operates from 3V to 36V single-supply or ±18V dual-supply and is widely deployed in power supply feedback loops, motor control signal conditioning, and sensor interface circuits.

For engineers reviewing the LM358BIDDFR datasheet, LM358BIDDFR pinout, LM358BIDDFR application, or LM358BIDDFR equivalent, this page delivers verified electrical specifications, validated SOT-23-8 pin functions, real-world use cases in industrial power and motor systems, and two technically documented alternative parts with explicit functional and thermal differences.

Technical Context

The LM358BIDDFR implements a bipolar-input, internally compensated two-stage op-amp architecture optimized for cost-sensitive industrial applications. Its input stage supports common-mode voltage down to V– (ground in single-supply mode), enabling direct low-side current sensing and battery monitoring without level-shifting circuitry.

It delivers stable unity-gain operation with 56° phase margin into 10kΩ//20pF loads, features integrated RF/EMI filtering for robustness in noisy environments, and maintains 35 V/mV minimum open-loop gain across –40°C to +85°C ambient temperature range.

Key Specifications

FAQ

What is the maximum operating temperature range for LM358BIDDFR?

The LM358BIDDFR is rated for operation from –40°C to +85°C ambient temperature. This range is validated per TI's SLOS068AB datasheet Section 5.3, and applies to all electrical characteristics unless otherwise noted. The device maintains ±3mV max input offset voltage and 300µA typical quiescent current across this full range, making it suitable for industrial environments such as factory automation controllers and outdoor power equipment.

Does LM358BIDDFR support single-supply operation with input signals at ground potential?

Yes, LM358BIDDFR supports true single-supply operation with common-mode input voltage extending to V– (ground). As specified in Section 5.3 of the datasheet, its input stage accepts signals from V– to (V+) – 2V at TA = –40°C to +85°C. This enables direct connection of ground-referenced sources like shunt resistors or thermistors without external biasing, simplifying sensor interface design in LM358BIDDFR-based circuits.

What is the capacitive load drive capability of LM358BIDDFR?

The LM358BIDDFR is characterized to drive up to 100pF capacitive loads while maintaining stability, as confirmed in Section 5.5 Electrical Characteristics. This value reflects tested performance with 10kΩ load and unity-gain configuration. For loads exceeding 100pF, external isolation resistor (e.g., 10–100Ω in series with output) is recommended to prevent peaking or oscillation-particularly critical in LM358BIDDFR applications driving long traces or ADC input capacitance.

How does the ESD robustness of LM358BIDDFR compare to legacy LM358 variants?

LM358BIDDFR provides ±2000V HBM ESD protection, significantly higher than legacy LM358 (±500V HBM) per Section 5.2 of the datasheet. This enhanced ruggedness stems from integrated EMI/RF filtering and process improvements in the B-version silicon. In practice, this reduces field failure rates in manufacturing and end-equipment exposed to static discharge-making LM358BIDDFR preferable for LM358BIDDFR deployments in handheld tools, serviceable appliances, and unshielded industrial panels.

Can LM358BIDDFR replace LM358 in existing designs without layout changes?

Yes, LM358BIDDFR is pin-to-pin compatible with LM358 in the same DDF (SOT-23-8) package and shares identical pinout per Figure 4-1 and Table 4-1. However, designers must verify that the improved specs-such as 1.2MHz GBW (vs. 0.7MHz), lower offset (±3mV vs. ±7mV), and 300µA IQ (vs. 350µA)-do not cause unintended behavior in legacy compensation networks or bandwidth-limited stages. LM358BIDDFR drop-in replacement is validated for most LM358-based feedback and signal conditioning circuits.
