Product details
Overview
LMV358IPWRQ1 from Texas Instruments is a dual, low-voltage (2.7 V to 5.5 V), rail-to-rail output operational amplifier qualified for automotive applications (−40°C to 125°C). It delivers 1 MHz unity-gain bandwidth, 1 V/µs slew rate, and 210 µA typical supply current per amplifier. Used in sensor signal conditioning and body control modules where space-constrained PCBs require low-power, robust analog front-ends.
For engineers reviewing the LMV358IPWRQ1 datasheet, LMV358IPWRQ1 pinout, LMV358IPWRQ1 application, or LMV358IPWRQ1 equivalent, key selection criteria include its AEC-Q100 qualification, TSSOP-8 package thermal performance (θJA = 149°C/W), rail-to-rail output swing at 2.7 V supply, and absence of crossover distortion in automotive-grade signal amplification.
Technical Context
The LMV358IPWRQ1 implements a CMOS input stage with complementary differential pairs enabling rail-to-rail output swing and common-mode input voltage range extending to ground. Its internal biasing supports stable operation across the full −40°C to 125°C automotive temperature range without external compensation.
It features a single-pole dominant-pole compensation scheme yielding 60° phase margin at unity gain with 2 kΩ load and 200 pF capacitive load, ensuring stability in sensor interface and feedback loop applications without requiring external compensation networks.
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 bandwidth-critical applications like throttle position sensor amplification up to ~100 kHz closed-loop response. |
| Slew Rate | 1 V/µs - ensures faithful reproduction of fast transients in motor control feedback signals without distortion. |
| Input Offset Voltage | 7 mV max (full temp range) - allows accurate DC-coupled amplification of low-level thermistor or strain gauge outputs. |
| Supply Current (per amp) | 210 µA typ at 25°C - reduces total system power draw in always-on vehicle modules such as door latch monitoring. |
| Common-Mode Input Range | −0.2 V to VCC + 0.2 V - accommodates inputs below ground (e.g., shunt-based current sensing) without clipping. |
| Output Swing (RL = 10 kΩ) | VCC − 100 mV (high), 65 mV (low) at 5 V - delivers near-full supply utilization for ADC reference scaling in battery monitoring circuits. |
Pinout & Package
TSSOP-8 package (PW drawing), 3.0 mm × 4.4 mm footprint, 0.65 mm pitch, moisture sensitivity level 1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amp 1) | Accepts negative feedback or differential signal input; referenced to GND or virtual ground in standard configurations. |
| 2 | Non-Inverting Input (Amp 1) | Accepts sensor signal or reference voltage; supports rail-to-rail common-mode range including ground. |
| 3 | Output (Amp 1) | Delivers rail-to-rail output swing; drives 2 kΩ loads directly without external buffering in most automotive interfaces. |
| 4 | GND | Power and signal reference plane; requires low-impedance connection to minimize noise coupling in mixed-signal PCB layouts. |
| 5 | Non-Inverting Input (Amp 2) | Independent input for second channel; electrically isolated from Amp 1 except via shared supply and substrate. |
| 6 | Inverting Input (Amp 2) | Supports independent feedback network; layout must avoid crosstalk with adjacent pins due to 0.65 mm pitch. |
| 7 | Output (Amp 2) | Second rail-to-rail output; usable for dual-sensor conditioning or active filter stages without additional ICs. |
| 8 | VCC+ | Single positive supply input; decoupling capacitor (0.1 µF ceramic) required within 5 mm for stable high-frequency operation. |
Key Features
| Feature | Design Value |
|---|---|
| No Crossover Distortion | Eliminates notch distortion in Class-AB output stage, critical for accurate amplification of low-amplitude audio or ultrasonic sensor signals. |
| Rail-to-Rail Output Swing | Enables maximum dynamic range utilization when interfacing with 12-bit ADCs operating from same 3.3 V rail, improving SNR by up to 2 bits. |
| AEC-Q100 Qualified | Validated for automotive underhood environments including temperature cycling, humidity bias, and mechanical shock per Grade 1 requirements. |
| Low Supply Current | 210 µA per amplifier allows dual-channel operation at <500 µA total, supporting ISO 26262 ASIL-B compliant always-on diagnostic circuits. |
| Ground-Sensing Input Range | Supports direct connection of resistive sensors (e.g., coolant temperature NTC) without level-shifting circuitry, reducing BOM count and layout area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDRQ1 | SOIC-8 package (θJA = 97°C/W); rated for −40°C to 85°C only; identical electrical specs. | Not qualified for underhood or transmission control units requiring 125°C operation. | Select when cost-sensitive cabin applications (e.g., infotainment) do not require extended temperature grade. |
| TSV912IQDRQ1 | Higher 8 MHz GBW, 4.5 V/µs slew rate, but 130 µA per amp; AEC-Q100 Grade 0 (−40°C to 150°C). | Overqualified for basic signal conditioning; better suited for active filters or higher-speed sensor interfaces. | Choose when design requires >1 MHz closed-loop bandwidth or enhanced thermal margin beyond 125°C. |
Compared with LMV358IDRQ1, LMV358IPWRQ1 offers extended temperature capability and smaller footprint but higher thermal resistance; versus TSV912IQDRQ1, it trades bandwidth and speed for lower power and proven cost-optimized implementation in legacy automotive platforms.

FAQ
What is the maximum operating temperature range for LMV358IPWRQ1?
The LMV358IPWRQ1 is qualified for operation from −40°C to +125°C per AEC-Q100 Grade 1 requirements, making it suitable for underhood applications including engine control, transmission control, and radiator fan drivers where ambient temperatures exceed 105°C.
Does LMV358IPWRQ1 support rail-to-rail input as well as output?
The LMV358IPWRQ1 supports rail-to-rail output swing but has a common-mode input voltage range extending from −0.2 V to VCC + 0.2 V - enabling ground-referenced inputs but not full rail-to-rail input. Inputs must remain within 0.2 V of either supply rail to maintain specified CMRR and offset performance.
Can LMV358IPWRQ1 drive a 2 kΩ load at 5 V supply while maintaining rail-to-rail output?
Yes - at VCC = 5 V and TA = 25°C, LMV358IPWRQ1 delivers high-level output swing to VCC − 40 mV and low-level swing to 120 mV into RL = 2 kΩ, satisfying rail-to-rail specification for most automotive ADC interfaces and LED driver bias networks.
Is LMV358IPWRQ1 pin-compatible with standard LM358 variants?
No - LMV358IPWRQ1 uses TSSOP-8 packaging with different pinout than DIP/SOIC-8 LM358 variants. While functional behavior is similar, direct PCB replacement requires layout revision due to 0.65 mm pitch and reversed output/inverting input positions relative to legacy footprints.
What is the typical supply current consumption of LMV358IPWRQ1 at 3.3 V?
At VCC = 3.3 V and TA = 25°C, LMV358IPWRQ1 draws 210 µA typical supply current per amplifier (420 µA total), consistent with its 2.7–5.5 V operating range and optimized for low-power automotive subsystems such as door module wake-up circuits and tire pressure sensor receivers.
