Product details
Overview
LMV341IDBVR from Texas Instruments is a single-channel, rail-to-rail output CMOS operational amplifier with active-low shutdown control, designed for low-voltage (2.7V–5.5V) battery-powered systems. It delivers 1 MHz gain bandwidth, 1 V/μs slew rate, and ultra-low 1 pA typical input bias current, enabling precision signal conditioning in space-constrained portable electronics.
For engineers reviewing the LMV341IDBVR datasheet, LMV341IDBVR pinout, LMV341IDBVR application, or LMV341IDBVR equivalent, key selection criteria include shutdown current (33 nA typ. at 5V), rail-to-rail output swing (≤30 mV from rails at 10 kΩ load), input offset voltage (0.25 mV typ.), and SOT-23-6 package compatibility with high-density PCB layouts.
Technical Context
The LMV341IDBVR uses a PMOS input stage to achieve ground-sensing capability (common-mode range extends to –0.2 V) and ultra-low input bias current, while its CMOS output stage enables rail-to-rail swing within 30 mV of supply rails. Its shutdown mode reduces supply current to 33 nA (typ. at 5 V) and places the output in high-impedance state.
Functional operation supports single-supply configurations from 2.5 V to 5.5 V, with guaranteed performance across –40°C to +125°C. Turn-on time from shutdown is 5 μs (typ.), and input referred voltage noise is 20 nV/√Hz at 10 kHz - critical for low-noise sensor front-ends and audio preamplifiers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct integration into Li-ion (3.0–4.2 V) and dual-cell alkaline (3.0 V) systems without regulation. |
| Gain Bandwidth Product | 1 MHz (typ.) - enables stable unity-gain buffering and low-frequency filtering up to ~100 kHz with phase margin >70°. |
| Slew Rate | 1 V/μs (typ.) - sufficient for 100 kHz full-scale sine wave output at 1 VPP without distortion. |
| Input Offset Voltage | 0.25 mV (typ.) - ensures ≤0.5% error in 12-bit ADC front-end applications with 2 V reference. |
| Shutdown Current | 33 nA (typ. at 5 V) - allows multi-year battery life in intermittent-sensing IoT nodes. |
| Input Bias Current | 1 pA (typ.) - minimizes voltage error across high-impedance sources (e.g., pH electrodes, photodiode transimpedance feedback). |
| Output Swing | Within 30 mV of rails (at 10 kΩ) - preserves dynamic range in low-voltage microcontroller I/O interfaces. |
Pinout & Package
LMV341IDBVR is housed in a 6-pin SOT-23 (DBV) package measuring 2.90 mm × 1.60 mm, optimized for high-density portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Noninverting input | Accepts analog signals down to –0.2 V; compatible with ground-referenced sensors. |
| 2 (GND) | Ground reference | Primary return path for supply and signal currents; must be low-impedance for noise immunity. |
| 3 (IN–) | Inverting input | Used for closed-loop configurations (e.g., inverting amplifiers, active filters); high-impedance node. |
| 4 (OUT) | Amplifier output | Rail-to-rail capable; drives loads ≥2 kΩ directly; high-Z during shutdown. |
| 5 (SHDN) | Active-low shutdown control | Pulled high (>4.5 V at 5 V supply) for normal operation; grounded to enter ultra-low-power mode. |
| 6 (V+) | Positive supply | Accepts 2.5–5.5 V; requires local 0.1 μF ceramic bypass capacitor to GND for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Enables full utilization of supply voltage headroom in 3.3 V and lower systems, maximizing SNR in ADC drivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV6001IDBVR | Higher 3.5 MHz GBW, 1.5 V/μs slew rate; 500 nA supply current; no shutdown pin. | Better for higher-speed filtering or active anti-aliasing; unsuitable where ultra-low shutdown current is required. | Select TLV6001IDBVR when bandwidth >1 MHz is needed and shutdown is unnecessary. |
| OPA316IDBVR | Lower 10 μV max offset, 0.15 μV/°C drift; 400 μA supply current; no shutdown; 10 MHz GBW. | Superior DC precision for instrumentation; higher power invalidates use in energy-harvesting or coin-cell designs. | Select OPA316IDBVR only when sub-50 μV offset and low drift outweigh shutdown and ultra-low IQ requirements. |
Compared with TLV6001IDBVR and OPA316IDBVR, the LMV341IDBVR uniquely balances rail-to-rail output, 1 pA input bias, and 33 nA shutdown current in SOT-23-6 - making it optimal for always-on, battery-limited systems where precision and power efficiency are co-constrained.

FAQ
What is the maximum supply voltage rating for LMV341IDBVR?
The absolute maximum supply voltage for LMV341IDBVR is 5.5 V. Operation above this level risks permanent damage per the Absolute Maximum Ratings table. Recommended operating range is 2.5 V to 5.5 V, with full electrical specifications guaranteed from 2.7 V to 5 V per the datasheet's test conditions. Always use a 0.1 μF ceramic bypass capacitor between V+ and GND to ensure stability under transient load conditions.
Does LMV341IDBVR support true rail-to-rail input?
LMV341IDBVR supports rail-to-rail *output* swing but not full rail-to-rail *input*. Its input common-mode voltage range extends from –0.2 V to (V+ – 1 V), meaning it accepts signals down to 0.2 V below ground (enabling ground-referenced inputs) but does not swing fully to the positive rail. This PMOS-input architecture enables 1 pA typical input bias current - a key trade-off for ultra-low-power precision applications.
How fast does LMV341IDBVR wake up from shutdown mode?
LMV341IDBVR has a typical turn-on time of 5 μs from shutdown to full operational output drive capability, measured at 25°C with V+ = 5 V. This parameter is consistent across the recommended operating temperature range (–40°C to +125°C). The output enters high-impedance state during shutdown, allowing safe multiplexing or sharing of output nodes in multi-amplifier systems.
What is the input offset voltage specification for LMV341IDBVR over temperature?
LMV341IDBVR has a typical input offset voltage of 0.25 mV at 25°C, with a maximum of 4.5 mV across the full operating temperature range (–40°C to +125°C). Its average temperature coefficient is 1.9 μV/°C (max), contributing <0.25 mV drift over a 100°C span. These values are specified under V+ = 5 V conditions and apply directly to the LMV341IDBVR variant in SOT-23-6 packaging.
Can LMV341IDBVR drive a 600 Ω load in audio applications?
LMV341IDBVR is not optimized for driving 600 Ω loads. Its output short-circuit current is rated at 85 mA (sourcing) and 50 mA (sinking) at 5 V, but sustained 600 Ω loading causes significant output swing degradation and increased THD. Datasheet THD+N testing at 600 Ω uses 1 VPP output - indicating suitability only for low-level line-driving, not headphone or speaker outputs. For 600 Ω, consider dedicated audio op-amps like OPA1611 or TPA6130A2.
