Texas Instruments LM358BAIDGKR

Overview

LM358BAIDGKR from Texas Instruments is a dual operational amplifier optimized for cost-sensitive industrial and consumer applications, featuring 2 mV max input offset voltage at 25°C, 1.2 MHz unity-gain bandwidth, and rail-to-rail input capability down to ground. It operates from 3 V to 36 V supply, draws only 300 µA per channel, and is housed in an 8-pin VSSOP package (DGK) with 3 mm × 4.9 mm footprint - ideal for space-constrained power supply monitoring and motor control feedback circuits.

For engineers reviewing the LM358BAIDGKR datasheet, LM358BAIDGKR pinout, LM358BAIDGKR application, or LM358BAIDGKR equivalent, this device is selected for precision single-supply signal conditioning where low quiescent current, ground-sensing inputs, and EMI/RF filtering are required - especially in AC inverters, multi-function printers, and uninterruptible power supplies.

Technical Context

The LM358BAIDGKR implements two independent high-voltage op amps in a single monolithic IC, each with internally compensated unity-gain stability and common-mode input range extending to the negative rail. Its architecture supports direct sensing of signals near ground without level-shifting circuitry, enabling simplified current-sense amplifier designs and battery voltage monitoring in 12 V/24 V systems.

It integrates on-die RF and EMI filters, achieving 2 kV HBM ESD robustness, and maintains stable operation across –40°C to +85°C ambient temperature. The device's 300 µA/ch quiescent current and 1.2 MHz GBW balance power efficiency with sufficient bandwidth for closed-loop motor control and power supply error amplification.

FAQ

What is the maximum supply voltage for LM358BAIDGKR?

The LM358BAIDGKR supports a maximum supply voltage of 36 V across V+ and V– terminals, with absolute maximum ratings specifying ±20 V differential or 40 V total. This allows direct use in 24 V industrial systems and 36 V battery-powered equipment without external regulators or voltage dividers.

Does LM358BAIDGKR support single-supply operation with input signals at ground?

Yes, the LM358BAIDGKR features a common-mode input voltage range that includes the negative rail (V–), enabling true single-supply operation with inputs referenced to ground. This is confirmed in Section 5.3 of the datasheet and makes it suitable for low-side current sensing and battery monitoring without input biasing networks.

What is the output swing capability of LM358BAIDGKR near the supply rails?

At 5 V supply and 1 mA load, the LM358BAIDGKR outputs swing to within 1.4 V of V+ and 0.75 V of V–. At light loads (50 µA), it achieves 1.35 V from V+ and 100 mV from V–. These values are specified in Section 5.5 Electrical Characteristics and confirm usable headroom for most feedback and comparator applications.

Is LM358BAIDGKR pin-compatible with legacy LM358 variants?

Yes, LM358BAIDGKR uses the standard 8-pin dual op amp pinout defined in Figure 4-1 of the datasheet and is fully pin-compatible with all LM358, LM358A, LM358B, and LM2904 variants in the same VSSOP-8 (DGK) package - including identical IN1–, IN1+, OUT1, V–, IN2+, IN2–, OUT2, and V+ assignments.

How does the EMI/RF filtering in LM358BAIDGKR improve system-level robustness?

The LM358BAIDGKR integrates on-die RF and EMI filters as stated in its Features section, which suppress high-frequency interference coupled into analog signal paths - particularly beneficial in motor control and inverter applications where PWM noise can corrupt sensor measurements. This reduces reliance on external ferrite beads or RC filters, simplifying layout and improving immunity per IEC 61000-4-3/4-6 standards.
