Product details
Overview
LMV358IPWRG4Q1 from Texas Instruments is a dual, rail-to-rail output operational amplifier qualified for automotive applications (AEC-Q100 Grade 1), operating from 2.7 V to 5.5 V supply, with 1 MHz unity-gain bandwidth, 1 V/µs slew rate, and 210 µA typical supply current per amplifier. It delivers rail-to-rail output swing into 10 kΩ loads and supports ground-sensing input common-mode range - ideal for battery-powered sensor signal conditioning in automotive body control modules.
For engineers reviewing the LMV358IPWRG4Q1 datasheet, LMV358IPWRG4Q1 pinout, LMV358IPWRG4Q1 application, or LMV358IPWRG4Q1 equivalent, key selection criteria include its AEC-Q100 qualification, TSSOP-8 package footprint compatibility, low-voltage rail-to-rail output performance at 2.7 V, and verified operation across −40°C to 125°C ambient temperature.
Technical Context
The LMV358IPWRG4Q1 implements a CMOS input stage with rail-to-rail output stage architecture, enabling full-swing operation from VCC to GND under light loads. Its input common-mode range extends to ground (−0.2 V to VCC − 1 V at 5 V), supporting single-supply transducer interfacing without level-shifting.
It features no crossover distortion due to complementary output transistor design, maintains stable unity-gain operation with ≥60° phase margin into 2 kΩ–100 kΩ loads, and exhibits <7 mV input offset voltage (typical) with 5 µV/°C drift - optimized for precision DC-coupled amplification in automotive analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct interface with 3.3 V and 5 V automotive microcontrollers and sensors. |
| Unity-Gain Bandwidth | 1 MHz - supports audio-band and low-speed control loop amplification (e.g., throttle position feedback). |
| Slew Rate | 1 V/µs - sufficient for 10 kHz full-scale sine wave output at 10 Vpp without distortion. |
| Input Offset Voltage | 7 mV max (full temp range) - ensures ≤0.7% gain error in 100× non-inverting configurations at room temperature. |
| Supply Current per Amplifier | 440 µA max (full temp range) - enables dual-amplifier operation within 1 mA total budget for ultra-low-power ECUs. |
| Output Swing (RL = 10 kΩ) | VCC − 40 mV (high), 65 mV (low) at 5 V - delivers true rail-to-rail dynamic range for ADC input scaling. |
| Common-Mode Input Range | −0.2 V to VCC − 1 V - allows direct connection of grounded thermistors or current-sense resistors. |
Pinout & Package
TSSOP-8 (PW) package: 3.0 mm × 4.4 mm body, 0.65 mm pitch, exposed pad not electrically connected. RoHS-compliant, green (Pb-free, no Sb/Br), MSL Level-1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier A) | Accepts feedback or differential input signals; high-impedance CMOS node (IIB ≤ 250 nA). |
| 2 | Non-Inverting Input (Amplifier A) | Direct sensor interface point; supports ground-referenced inputs down to −0.2 V. |
| 3 | Output (Amplifier A) | Rail-to-rail capable (VCC − 40 mV / 65 mV at 5 V); drives 10 kΩ loads to full supply rails. |
| 4 | Ground (GND) | Power and signal reference return; must be low-impedance path to minimize noise coupling. |
| 5 | Non-Inverting Input (Amplifier B) | Independent second channel input; identical electrical specs to Pin 2. |
| 6 | Inverting Input (Amplifier B) | Second channel feedback node; shares same bias current and offset characteristics as Pin 1. |
| 7 | Output (Amplifier B) | Second independent rail-to-rail output; fully isolated from Channel A except via shared supply pins. |
| 8 | Positive Supply (VCC+) | Single 2.7–5.5 V supply input; decoupling capacitor (0.1 µF) required within 5 mm of this pin. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358QDRQ1 | SOIC-8 package (4.9 mm × 3.9 mm), same electrical specs, same AEC-Q100 Grade 1 rating. | Requires PCB layout change due to larger footprint and 1.27 mm pitch; better thermal dissipation (θJA = 97°C/W vs. 149°C/W). | Select when board space allows SOIC and higher power dissipation margin is needed. |
| TSV912IQDT | Higher GBW (8 MHz), lower input offset (1.5 mV typ), but higher supply current (820 µA typ) and not AEC-Q100 qualified. | Not suitable for safety-critical or production automotive systems requiring qualification evidence. | Select only for non-automotive industrial prototypes needing higher speed and precision. |
Compared with LMV358QDRQ1 and TSV912IQDT, the LMV358IPWRG4Q1 uniquely balances AEC-Q100 compliance, compact TSSOP-8 footprint, and ultra-low quiescent current - making it optimal for space-constrained, cost-sensitive automotive modules where qualification and thermal profile are critical.

FAQ
What is the maximum operating temperature range for LMV358IPWRG4Q1?
The LMV358IPWRG4Q1 is qualified for operation from −40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This rating is validated across all electrical parameters in the datasheet's "electrical characteristics at specified free-air temperature range" tables, with full-spec performance guaranteed across the entire range.
Does LMV358IPWRG4Q1 support rail-to-rail input operation?
No, the LMV358IPWRG4Q1 does not support rail-to-rail input. Its common-mode input voltage range is specified as −0.2 V to VCC − 1 V at 5 V supply, meaning it accepts inputs down to 0.2 V below ground but only up to 4 V when VCC = 5 V. However, it does provide true rail-to-rail output swing.
Is LMV358IPWRG4Q1 pin-compatible with standard LM358 devices?
No, LMV358IPWRG4Q1 is not pin-compatible with legacy LM358 variants. While both are dual op-amps in 8-pin packages, LM358 uses different pin assignments (e.g., LM358 SOIC places VCC on Pin 8 and GND on Pin 4), whereas LMV358IPWRG4Q1 follows TI's modern pinout: GND on Pin 4 and VCC on Pin 8. Direct replacement requires PCB redesign.
What is the typical input bias current of LMV358IPWRG4Q1 at 25°C?
The typical input bias current of LMV358IPWRG4Q1 is 15 nA at 25°C, with a maximum of 500 nA across the full −40°C to +125°C operating range. This low bias current minimizes voltage errors in high-impedance sensor interfaces such as thermistor networks or photodiode transimpedance stages.
Can LMV358IPWRG4Q1 drive capacitive loads without instability?
LMV358IPWRG4Q1 is stable for capacitive loads up to 100 pF with 2 kΩ series resistance, as confirmed by Figure 6–9 in the datasheet. For loads >100 pF, external isolation (e.g., 20–100 Ω series resistor) is required at the output to maintain ≥60° phase margin and prevent peaking or oscillation.
