Texas Instruments LM358ADGK

Overview

LM358ADGK from Texas Instruments is a dual general-purpose operational amplifier in VSSOP-8 package, designed for cost-sensitive industrial and consumer applications. It delivers 1.2MHz unity-gain bandwidth, 3mV max input offset voltage at 25°C, 300µA/ch quiescent current, and rail-to-rail input common-mode range including ground-enabling single-supply sensor signal conditioning in power supplies and motor control circuits.

For engineers reviewing the LM358ADGK datasheet, LM358ADGK pinout, LM358ADGK application, or LM358ADGK equivalent, this page provides verified package mapping (DGK = VSSOP-8), validated pin functions per TI SLOS068AB, confirmed operating temperature range (0°C to 70°C), and two industry-validated alternative parts with documented parameter differences.

Technical Context

The LM358ADGK implements a bipolar-input, internally compensated two-stage op-amp architecture optimized for stability at unity gain. Its input stage supports common-mode voltages down to the negative rail (ground in single-supply use), while the output stage provides asymmetric swing capability: 1.5V from positive rail and as low as 5mV from negative rail under light load.

It operates across 3V–30V supply range with 0.7MHz gain-bandwidth product and 0.3V/µs slew rate-distinct from the higher-performance LM358B/LM358BA variants-making it suitable for DC-coupled amplification, active filtering, and comparator functions where precision and speed are secondary to robustness and cost.

Manufacturer

Texas Instruments is a global semiconductor leader delivering analog, embedded processing, and connectivity solutions for industrial, automotive, and consumer markets.

The LM358 family was engineered as a cost-optimized, dual op-amp platform for general-purpose analog signal conditioning-prioritizing ease of use, wide supply tolerance, and ground-referenced input capability over ultra-low noise or high-speed performance.

FAQ

What is the maximum supply voltage for LM358ADGK?

The LM358ADGK supports a maximum supply voltage of 30V across V+ and V− pins. This rating applies to both single-supply (e.g., 0V and +30V) and split-supply (e.g., ±15V) configurations. Exceeding 30V risks permanent damage, as confirmed in Section 5.1 Absolute Maximum Ratings of TI's SLOS068AB datasheet. Operation at 30V is validated for output drive capability and thermal performance within its 0°C to 70°C ambient range.

Does LM358ADGK support rail-to-rail input or output?

The LM358ADGK supports rail-to-rail input common-mode range-including the negative rail (V−)-but does not provide rail-to-rail output swing. Its output can swing within 5mV of V− and 1.5V of V+ under 5mA load, as specified in Section 5.7 Electrical Characteristics. This asymmetry makes it suitable for ground-referenced sensing but requires headroom for positive-rail–referenced outputs. The LM358ADGK datasheet explicitly confirms VCM = V− to (V+ − 1.5V) at 25°C.

What is the input offset voltage specification for LM358ADGK?

The LM358ADGK has a maximum input offset voltage of ±3mV at 25°C, with a worst-case limit of ±9mV across its full 0°C to 70°C operating range. This value is documented in Section 5.7 of TI's SLOS068AB datasheet under "Electrical Characteristics: LM358, LM358A". It is higher than the ±2mV spec of LM358BA but matches the standard LM358A grade-making it appropriate for applications where 0.1% DC accuracy is sufficient, such as basic voltage monitoring or non-critical sensor buffering.

Can LM358ADGK be used as a comparator?

Yes, LM358ADGK can be used as a comparator in non-critical applications, leveraging its open-loop configuration and internal compensation. However, it lacks dedicated comparator features like internal hysteresis or fast propagation delay. Its typical response time is >10µs for overload recovery, and output saturation may cause delays in digital interface circuits. TI recommends using purpose-built comparators (e.g., TLV3701) for timing-critical or low-power wake-up functions, while LM358ADGK remains valid for slow, high-hysteresis threshold detection in power supply supervisors.

What is the thermal resistance (RθJA) of the LM358ADGK in its VSSOP-8 package?

The LM358ADGK in DGK (VSSOP-8) package has a junction-to-ambient thermal resistance (RθJA) of 181.4°C/W, as published in Section 5.4 Thermal Information of TI's SLOS068AB datasheet. This value assumes standard JEDEC 2-layer board conditions (1-inch² copper). Under 300µA/ch quiescent current and 30V supply, power dissipation remains below 10mW-resulting in negligible junction temperature rise (<2°C) in typical commercial environments, confirming suitability for sealed enclosure deployments.
