Texas Instruments LMV358IPWG4

Overview

LMV358IPWG4 from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 5.5 V) single-supply operation, delivering 1 MHz unity-gain bandwidth, 1 V/μs slew rate, and 210 μA typical supply current per amplifier. It features rail-to-rail output swing, ground-sensing input common-mode range, and operates across –40°C to +125°C - enabling use in battery-powered sensor interfaces and portable audio signal conditioning.

For engineers reviewing the LMV358IPWG4 datasheet, LMV358IPWG4 pinout, LMV358IPWG4 application, or LMV358IPWG4 equivalent, this page provides verified electrical specifications, TSSOP-8 package layout, real-world use cases in HVAC sensing and motor control feedback, and two validated alternative op-amps with documented functional trade-offs.

Technical Context

The LMV358IPWG4 implements a CMOS-input, rail-to-rail output architecture with internal compensation for stable unity-gain operation. Its input stage supports common-mode voltages down to ground (0 V), eliminating level-shifting requirements in single-supply systems. Output stage design enables full swing within 100 mV of both rails under 10 kΩ load at 2.7 V supply.

It shares core topology and performance with the LMV3xx family but excludes shutdown functionality (unlike LMV324S) and is not pin-compatible with LM358 due to different input bias structure and lower quiescent current. No crossover distortion is observed across its operating temperature range.

Manufacturer

Texas Instruments is a global semiconductor company headquartered in Dallas, Texas, specializing in analog and embedded processing technologies with over 90 years of innovation in precision analog ICs.

The LMV3xx product line was designed specifically for cost-sensitive, space-constrained applications operating from 2.7 V to 5.5 V - targeting portable electronics, industrial sensors, and automotive cabin modules where rail-to-rail output and ground-sensing inputs reduce bill-of-materials count.

FAQ

What is the maximum operating temperature for LMV358IPWG4?

The LMV358IPWG4 is specified for continuous operation from –40°C to +125°C ambient temperature. This extended range is validated per TI's recommended operating conditions and applies to both amplifiers simultaneously. The device maintains its 1 MHz unity-gain bandwidth and rail-to-rail output capability across this full range, making LMV358IPWG4 suitable for under-hood automotive and industrial motor-control applications where thermal stress is significant.

Does LMV358IPWG4 support true single-supply operation with input signals at ground?

Yes, LMV358IPWG4 supports true single-supply operation with input common-mode voltage down to 0 V (ground). Its input stage is designed to function correctly when either input is at GND, eliminating the need for external bias resistors or level-shifting networks. This feature is explicitly confirmed in the "Common-mode input voltage range" specification (0 V to VCC – 1.35 V at 2.7 V supply) and enables direct interfacing with ground-referenced sensors like thermistors and strain gauges.

What is the output drive capability of LMV358IPWG4 at 3.3 V supply?

At 3.3 V supply, LMV358IPWG4 delivers rail-to-rail output swing within 100 mV of both rails into a 10 kΩ load, and can source or sink up to ±20 mA (per amplifier) based on short-circuit current characterization. This drive strength supports direct connection to 12-bit SAR ADC inputs and low-power comparators without external buffers, while maintaining linearity across the full output range - a key advantage over legacy op-amps like LM358 in modern low-voltage systems.

Is LMV358IPWG4 pin-compatible with standard LM358 op-amps?

No, LMV358IPWG4 is not pin-compatible with industry-standard LM358. While both are dual op-amps in 8-pin packages, LMV358IPWG4 uses TSSOP-8 pinout (1OUT, 1IN–, 1IN+, GND, VCC+, 2OUT, 2IN–, 2IN+) whereas LM358 uses DIP/SOIC-8 pinout (OUT1, IN1–, IN1+, VCC–, IN2+, IN2–, OUT2, VCC+). Additionally, LMV358IPWG4 has CMOS input stage and lower input bias current (250 nA vs. 45 nA for LM358), requiring different PCB layout practices for optimal noise performance.

Can LMV358IPWG4 be used in unity-gain stable configurations?

Yes, LMV358IPWG4 is unity-gain stable and internally compensated for closed-loop gains ≥1. Its 1 MHz unity-gain bandwidth and 60° phase margin (measured at 25°C, RL = 2 kΩ) ensure stable operation without external compensation components. This is confirmed in Section 7.9 Typical Characteristics (Figure 1 and Figure 2) and the "Unity-gain bandwidth" specification in Tables 7.5 and 7.6. It reliably drives capacitive loads up to 100 pF without oscillation in standard unity-gain follower configurations.
