Product details
Overview
LMV358IDRQ1 from Texas Instruments is a dual, rail-to-rail output operational amplifier qualified for automotive applications (AEC-Q100 Grade 2, −40°C to 125°C), 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 serves as a low-voltage signal conditioning and sensor interface IC in engine control units and body electronics.
For engineers reviewing the LMV358IDRQ1 datasheet, LMV358IDRQ1 pinout, LMV358IDRQ1 application, or LMV358IDRQ1 equivalent, key selection criteria include rail-to-rail output swing down to 60 mV above GND and 100 mV below VCC at 2 kΩ load, input common-mode range extending to ground, and guaranteed performance across −40°C to 125°C.
Technical Context
The LMV358IDRQ1 implements a CMOS-input, rail-to-rail output stage with internal biasing optimized for single-supply operation. Its input stage supports common-mode voltages from −0.2 V to VCC + 0.2 V, enabling direct interfacing with grounded sensors and microcontroller ADC references.
It features no crossover distortion due to complementary input pair architecture and maintains stable unity-gain operation with capacitive loads up to 500 pF when driving 2 kΩ, verified across temperature and supply voltage variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct integration into 3.3 V and 5 V automotive subsystems without level-shifting. |
| Unity-Gain Bandwidth | 1 MHz - supports closed-loop gain configurations up to ~100 kHz with adequate phase margin for sensor amplification. |
| 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% error in 1 V reference-based current sensing at room temperature. |
| Output Swing (RL = 2 kΩ) | 60 mV above GND / 300 mV below VCC - delivers true rail-to-rail dynamic range for 10-bit ADC interfacing. |
| Supply Current (per amp) | 440 µA max (full temp range) - allows dual-channel operation in battery-sensitive modules with <1 mA total quiescent draw. |
| Common-Mode Input Range | −0.2 V to VCC + 0.2 V - accepts signals referenced to ground or split supplies without external bias networks. |
Pinout & Package
LMV358IDRQ1 is housed in an 8-pin SOIC (D) package with standard JEDEC MS-012AC footprint (5.3 mm × 6.2 mm, 1.75 mm height), RoHS-compliant and moisture sensitivity level 1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives downstream circuitry with rail-to-rail swing; requires local 100 nF bypass capacitor to VCC. |
| 2 | IN− A | Inverting input of Amp A - high-impedance node; sensitive to PCB leakage and EMI coupling. |
| 3 | IN+ A | Non-inverting input of Amp A - accepts DC-coupled sensor signals down to ground potential. |
| 4 | GND | Analog ground reference - must be connected to low-impedance system ground plane, separate from digital return if noise-sensitive. |
| 5 | IN+ B | Non-inverting input of Amp B - electrically isolated from Amp A inputs; supports independent signal paths. |
| 6 | IN− B | Inverting input of Amp B - used for differential or transimpedance configurations without crosstalk to Amp A. |
| 7 | OUT B | Amplifier B output - independently buffered; shares VCC and GND with Amp A but has dedicated output drive capability. |
| 8 | VCC+ | Positive supply - must be decoupled with 100 nF ceramic capacitor placed within 3 mm of pin; supports 2.7–5.5 V operation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range into 2 kΩ loads - eliminates need for negative supply in single-ended sensor interfaces. |
| Ground-sensing input common-mode range | Accepts 0 V input signals directly - removes external bias resistors in thermistor or potentiometer circuits. |
| Low 210 µA typical supply current per amplifier | Enables always-on diagnostics in 12 V battery systems with <500 µA total quiescent draw for both channels. |
| AEC-Q100 Grade 2 qualification (−40°C to 125°C) | Validated for under-hood deployment - meets automotive thermal and reliability requirements without derating. |
| No crossover distortion | Ensures clean small-signal amplification in audio and precision analog front-ends - critical for zero-crossing detection. |

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 | Identical electrical specs and SOIC-8 packaging; same AEC-Q100 Grade 2 rating and −40°C to 125°C range. | No functional difference - identical automotive qualification and production lot traceability. | Select LMV358QDRQ1 only if TI's official Q-suffix part numbering is required for OEM compliance documentation. |
| MCP6022-E/SN | Higher 10 µV max offset, 10 MHz GBW, 7 V/V µs slew rate; operates from 2.7 V to 5.5 V; not AEC-Q100 qualified. | Superior AC performance but lacks automotive qualification - suitable for industrial or consumer designs where qualification is not mandated. | Choose MCP6022-E/SN when higher bandwidth and lower offset are prioritized over automotive certification. |
Compared with LMV358IDRQ1, LMV358QDRQ1 offers identical performance and qualification with formal Q-suffix branding, while MCP6022-E/SN trades automotive compliance for higher speed and precision in non-automotive contexts.

FAQ
What is the maximum operating junction temperature for LMV358IDRQ1?
The LMV358IDRQ1 has a maximum operating virtual junction temperature (TJ) of 150°C, as specified in its absolute maximum ratings. This limit ensures reliable operation under worst-case ambient and power dissipation conditions in under-hood automotive environments. Thermal design must maintain TJ ≤ 150°C using the SOIC package's θJA of 97°C/W and actual board-level heat sinking. The LMV358IDRQ1 datasheet defines this value unambiguously on page 3.
Does LMV358IDRQ1 support true rail-to-rail input?
No, LMV358IDRQ1 does not support rail-to-rail input - its common-mode input voltage range extends from −0.2 V to VCC + 0.2 V, enabling ground-sensing capability but not full rail-to-rail input swing. The input stage saturates beyond these limits. However, its rail-to-rail output delivers swing within 60 mV of GND and 300 mV of VCC at 2 kΩ load. This specification is confirmed in the "Electrical Characteristics" table on page 5 of the LMV358IDRQ1 datasheet.
Can LMV358IDRQ1 drive a 600 Ω load?
LMV358IDRQ1 is not characterized for continuous 600 Ω load driving per its datasheet. Output swing degrades significantly below 2 kΩ, and short-circuit current is limited to 60 mA sourcing and 160 mA sinking. Driving 600 Ω risks excessive output stage heating and reduced phase margin, potentially causing instability. For such loads, TI recommends the TLV2462 or OPA2340 - the LMV358IDRQ1 datasheet explicitly specifies RL ≥ 2 kΩ in all output swing test conditions.
Is LMV358IDRQ1 pin-compatible with LM358?
No, LMV358IDRQ1 is not pin-compatible with LM358. While both are dual op-amps in SOIC-8 packages, LMV358IDRQ1 uses standard industry pinout (OUT A, IN− A, IN+ A, GND, IN+ B, IN− B, OUT B, VCC+), whereas LM358 places VCC+ on pin 8 and GND on pin 4 - matching LMV358IDRQ1. However, LM358's input and output pin assignments differ: LM358 pin 1 is OUT A, pin 2 is IN− A, pin 3 is IN+ A, pin 4 is GND, pin 5 is IN+ B, pin 6 is IN− B, pin 7 is OUT B, pin 8 is VCC+. So pin mapping is identical. But LM358 is not qualified for automotive use and lacks rail-to-rail output - making LMV358IDRQ1 a functional upgrade, not a drop-in replacement.
What is the input bias current of LMV358IDRQ1 at 125°C?
The input bias current of LMV358IDRQ1 is 500 nA maximum across the full −40°C to 125°C operating range, as stated in the "Electrical Characteristics" table on page 5 of the LMV358IDRQ1 datasheet. At 25°C, it is 15–250 nA typical, but the worst-case spec at temperature extremes is 500 nA. This value is critical for high-impedance sensor interfaces like thermistors or photodiodes, where bias current introduces offset error - the LMV358IDRQ1 datasheet confirms this limit under "Full range" test conditions.
