Texas Instruments LM358PWRG4-JF

Overview

LM358PWRG4-JF from Texas Instruments is a dual general-purpose operational amplifier in TSSOP-8 package, featuring 3V–36V wide supply range, 1.2MHz unity-gain bandwidth, 300µA/ch quiescent current, and rail-to-rail input (including ground), enabling single-supply sensor signal conditioning in industrial power supplies and motor control circuits.

For engineers reviewing the LM358PWRG4-JF datasheet, LM358PWRG4-JF pinout, LM358PWRG4-JF application, or LM358PWRG4-JF equivalent, key selection criteria include input offset voltage (≤3mV at 25°C), common-mode input range to ground, EMI/RF filtering, thermal performance in TSSOP-8, and compatibility with cost-sensitive analog front-ends requiring dual op-amp integration.

Technical Context

The LM358PWRG4-JF implements a bipolar-input, internally compensated two-stage transconductance amplifier architecture optimized for DC precision and low-frequency AC signal amplification. It supports single-supply operation down to 3V with input common-mode voltage extending to V–, and delivers stable unity-gain performance without external compensation.

Its output stage provides 20mA sink/source capability and 100pF capacitive load drive, while integrated EMI/RF filters suppress high-frequency interference-critical for use in noisy environments like motor drives and power supply feedback loops.

FAQ

What is the maximum supply voltage for LM358PWRG4-JF?

The LM358PWRG4-JF supports a maximum supply voltage of 36V across V+ and V– terminals. This rating applies to both single-supply (e.g., V+ = 36V, V– = 0V) and split-supply (e.g., V+ = ±18V) configurations. Exceeding this limit risks permanent damage, as specified in Absolute Maximum Ratings. The device maintains full functionality across its entire 3V–36V operating range, making LM358PWRG4-JF suitable for 24V industrial systems and 36V battery-powered equipment.

Does LM358PWRG4-JF support rail-to-rail input?

LM358PWRG4-JF supports rail-to-rail input only on the negative side: its common-mode input voltage range extends to V– (including ground), but stops 1.5V below V+ at room temperature and 2V below V+ over full temperature range. It does not support rail-to-rail output-output swing is typically 1.5V from V+ and 20mV from V– at 1mA load. This asymmetric input range makes LM358PWRG4-JF ideal for ground-referenced sensing but unsuitable for full-scale V+-referenced inputs without external biasing.

What is the input offset voltage specification for LM358PWRG4-JF?

The LM358PWRG4-JF has a maximum input offset voltage of ±3mV at 25°C, consistent with the LM358B variant. Over the full operating temperature range (–40°C to +85°C), the offset voltage increases to ±4mV. This value is measured differentially between IN1+/IN1– and IN2+/IN2–, and applies to both amplifiers independently. The typical offset is ±0.3mV, supporting precision applications such as current-sense amplification where sub-millivolt errors are acceptable. LM358PWRG4-JF does not meet the tighter ±2mV spec of the LM358BA variant.

Can LM358PWRG4-JF drive capacitive loads?

Yes, LM358PWRG4-JF is characterized to drive up to 100pF capacitive loads without oscillation, as confirmed in the Electrical Characteristics table. This capability supports direct connection to ADC input capacitors, long PCB traces, or small bypass networks. For loads exceeding 100pF, external series resistance (typically 10–100Ω) is recommended at the output to maintain phase margin. The device's 56° phase margin and unity-gain stability ensure robust performance even with moderate capacitive loading-critical for LM358PWRG4-JF use in sensor signal chains feeding successive approximation register (SAR) ADCs.

Is LM358PWRG4-JF pin-compatible with other LM358 variants?

Yes, LM358PWRG4-JF is pin-compatible with all standard 8-pin LM358 family members in TSSOP-8 (PW) package, including LM358B, LM358BA, LM2904B, and LM2904BA. Pin functions match Table 4-1 exactly: OUT1, IN1–, IN1+, V–, IN2+, IN2–, OUT2, V+. However, electrical differences exist-such as EMI filtering (present in LM358PWRG4-JF/LM358B but absent in legacy LM358), offset voltage (3mV max vs 7mV max), and temperature range (–40°C to +85°C). Therefore, while LM358PWRG4-JF can replace older variants in the same footprint, full functional equivalence requires verification of these parameters in the target application.
