Product details
Overview
LMV341QDBVRQ1 from Texas Instruments is an AEC-Q100 qualified single-channel CMOS operational amplifier designed for automotive signal conditioning in 2.7V–5.5V systems. It delivers rail-to-rail output swing, 1 MHz unity-gain bandwidth, 1 V/μs slew rate, and ultra-low 1 pA input bias current - enabling precision sensor interfacing in battery-powered ADAS front-end modules.
For engineers reviewing the LMV341QDBVRQ1 datasheet, LMV341QDBVRQ1 pinout, LMV341QDBVRQ1 application, or LMV341QDBVRQ1 equivalent, key selection criteria include its –40°C to 125°C operating range, shutdown functionality with 5 μs turn-on time, and low 100 μA supply current per channel under 2.7V operation.
Technical Context
The LMV341QDBVRQ1 uses a PMOS input stage to achieve femtoampere-level input bias current and stable offset voltage (0.25 mV typical) across temperature. Its rail-to-rail output stage supports full-swing operation into 2 kΩ loads with <60 mV headroom at both rails under 2.7V supply.
It integrates an active shutdown pin (SHDN) that reduces supply current to ≤1 μA while preserving fast wake-up (5 μs), and features robust ESD protection (2 kV HBM) and phase-stable operation with ≥70° phase margin into capacitive loads up to 1 nF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5V to 5.5V - supports direct connection to automotive 3.3V or 5V rails without regulation |
| Unity-Gain Bandwidth | 1 MHz - enables stable closed-loop gain configurations up to 100 kHz with adequate phase margin |
| Slew Rate | 1 V/μs - sufficient for 100 kHz sine wave output at 1 VPP without distortion |
| Input Bias Current | 1 pA typical - minimizes voltage error in high-impedance sensor bridges and photodiode amplifiers |
| Output Swing | Within 5 mV of rails (RL = 10 kΩ, 2.7V) - maximizes dynamic range in low-voltage data acquisition |
| Shutdown Current | ≤1 μA - allows power gating in always-on vehicle subsystems without significant quiescent drain |
| Input Offset Voltage | 0.25 mV typical - ensures <0.5% gain error in 12-bit ADC front-ends with 2.5V reference |
Pinout & Package
SOT-23-6 (DBV) package: compact 2.9 mm × 1.6 mm footprint with gull-wing leads, rated for surface-mount reflow per JEDEC Level-1 (260°C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (IN+) | Non-Inverting Input | High-Z sensor interface point; common-mode range extends to –0.2V below GND |
| 3 (V−) | Ground Reference | Return path for supply and signal; must be low-impedance for noise immunity |
| 4 (OUT) | Amplifier Output | Rail-to-rail capable; drives 2 kΩ loads with <60 mV saturation at 2.7V supply |
| 5 (V+) | Positive Supply | Single-supply input; accepts 2.5–5.5V with internal regulation for internal bias generation |
| 6 (SHDN) | Shutdown Control | Active-high logic input; pulls supply current to ≤1 μA when driven <0.2V |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV911IQDBVRQ1 | Higher 8 MHz GBW but 150 μA supply current; no shutdown pin | Lacks power-gating capability; unsuitable for duty-cycled sensor nodes | Prefer when wideband AC coupling is required and continuous operation is acceptable |
| LMV931QDBVRQ1 | Same SOT-23-6 package and shutdown function, but 1.5 MHz GBW and 120 μA ICC | Higher noise (30 nV/√Hz vs. 20 nV/√Hz at 10 kHz) and lower PSRR (60 dB) | Select when cost sensitivity outweighs noise/PSRR requirements in non-critical body electronics |
Compared with TSV911IQDBVRQ1 and LMV931QDBVRQ1, the LMV341QDBVRQ1 uniquely balances ultra-low input bias (1 pA), integrated shutdown, and automotive temperature range - making it optimal for high-impedance, power-gated sensor interfaces where leakage and wake latency are design constraints.

FAQ
What is the maximum operating temperature for LMV341QDBVRQ1?
The LMV341QDBVRQ1 is rated for continuous operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This specification is validated across all electrical parameters in the datasheet, including input offset voltage drift, supply current stability, and output swing performance - ensuring reliable function in engine bay and powertrain control environments where thermal stress is extreme.
Does LMV341QDBVRQ1 support dual-supply operation?
No, the LMV341QDBVRQ1 is optimized for single-supply operation from 2.5V to 5.5V. Its input common-mode range extends to –0.2V below ground and up to 0.8V below V+, and its rail-to-rail output operates between GND and V+. While it can function with split supplies if GND is referenced to mid-rail, TI does not characterize or guarantee performance under dual-supply conditions - the LMV341QDBVRQ1 datasheet specifies only single-supply test conditions.
How does the shutdown pin (SHDN) function on LMV341QDBVRQ1?
The SHDN pin on LMV341QDBVRQ1 is an active-high digital control input. When pulled to ≥1.7V (at 2.7V supply) or ≥3.1V (at 5V supply), the amplifier operates normally. When held ≤0.2V, the device enters shutdown mode, reducing supply current to ≤1 μA. The 5 μs turn-on time is measured from SHDN rising edge to output settling within 1% of final value - critical for low-duty-cycle sensor wake-up sequences in automotive body controllers.
What is the typical input-referred voltage noise of LMV341QDBVRQ1 at 10 kHz?
The LMV341QDBVRQ1 exhibits 20 nV/√Hz typical input-referred voltage noise at 10 kHz, as specified in Section 1 of the datasheet. This value is measured under standard conditions (V+ = 2.7V, TA = 25°C, RL > 1 MΩ) and remains stable across the full –40°C to 125°C temperature range. At 1 kHz, the noise is 39–40 nV/√Hz, confirming low-noise performance across audio and sensor bandwidths relevant to automotive cabin microphones and ultrasonic parking assist.
Is LMV341QDBVRQ1 pin-compatible with other SOT-23-6 op-amps?
The LMV341QDBVRQ1 uses a non-standard SOT-23-6 pinout: Pin 1 = IN−, Pin 2 = IN+, Pin 3 = GND, Pin 4 = OUT, Pin 5 = V+, Pin 6 = SHDN. This differs from industry-standard pinouts like the TSZ121 or MCP6001, which place V+ on Pin 8 (SOIC) or Pin 5 (SOT-23-5). No drop-in replacement exists - PCB layout must allocate space for the SHDN function and observe TI's recommended bypass capacitor placement (0.1 μF ceramic between Pin 5 and Pin 3) to ensure stability.
