Product details
Overview
TLV341AIDBVR from Texas Instruments is a single-channel, low-voltage, rail-to-rail output CMOS operational amplifier with active-low shutdown control, 1.25 mV max input offset voltage (25°C, A grade), 2.3 MHz gain bandwidth, and 70 μA typical supply current per channel. It operates from 1.5 V to 5.5 V and is used in battery monitoring, audio preamplification, and portable equipment signal conditioning.
For engineers reviewing the TLV341AIDBVR datasheet, TLV341AIDBVR pinout, TLV341AIDBVR application, or TLV341AIDBVR equivalent, key selection criteria include shutdown current (10 pA typ), input bias current (1 pA typ), rail-to-rail output swing (≤25 mV from rails at 10 kΩ), common-mode input range (–0.2 V to V+ – 0.5 V), and extended industrial temperature support (–40°C to 125°C).
Technical Context
The TLV341AIDBVR uses a PMOS input stage enabling ultra-low input bias current (1 pA typ) and ground-sensing capability, with common-mode input extending to –0.2 V. Its CMOS output stage delivers rail-to-rail swing within 25 mV of supply rails under 10 kΩ load.
It features an active-low SHDN pin that places the amplifier in high-impedance output state with 10 pA typical shutdown current and 5 μs typical wake-up time. The device is specified for 1.5 V to 5.5 V single-supply operation and supports full functionality across –40°C to 125°C.
Key Specifications

| Input Offset Voltage (max) | 1.25 mV at 25°C (A grade) - ensures ≤0.5% error in 12-bit precision DC-coupled sensor interfaces |
| Gain Bandwidth Product | 2.3 MHz - supports stable unity-gain buffer and closed-loop gain ≥10 up to ~200 kHz |
| Supply Current (typ) | 70 μA per channel - allows >1-year operation on 220 mAh coin cell in duty-cycled monitoring |
| Rail-to-Rail Output Swing | ≤25 mV from rails (10 kΩ load) - maximizes dynamic range in low-voltage ADC front-ends |
| Shutdown Current (typ) | 10 pA - reduces system standby power to sub-nW levels, critical for always-on sensing nodes |
| Input Bias Current (typ) | 1 pA - prevents significant voltage error across high-impedance sources (>100 MΩ) |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Noninverting input | High-impedance PMOS node; accepts signals down to –0.2 V for true single-supply operation |
| 2 (GND) | Ground reference | Primary return path for supply and signal currents; must be low-impedance for noise immunity |
| 3 (IN−) | Inverting input | Differential input node; matched to IN+ for <1.25 mV offset in A-grade devices |
| 4 (OUT) | Amplifier output | CMOS push-pull stage delivering rail-to-rail swing with 12 mA short-circuit capability |
| 5 (SHDN) | Active-low shutdown control | Pulled low to disable amplifier; output goes high-Z, ICC drops to 10 pA typ |
| 6 (V+) | Positive supply | Accepts 1.5–5.5 V; requires local 0.1 µF ceramic bypass to GND for stability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV341IDBVR | Standard grade (4 mV max VIO at 25°C) vs. A grade (1.25 mV); identical pinout, specs, and packaging | Suitable where ±0.1% accuracy is not required; lower cost for consumer-grade signal chains | Select TLV341IDBVR if offset-critical DC performance is unnecessary and BOM cost optimization is prioritized. |
| OPA316IDBVR | Higher GBW (10 MHz), lower noise (11 nV/√Hz), but higher IQ (400 μA); no shutdown pin; same SOT-23-6 package | Better for wideband audio or fast sensor interfaces; unsuitable for ultra-low-power shutdown use cases | Choose OPA316IDBVR only when bandwidth or noise dominates over power and shutdown capability. |
Compared with TLV341IDBVR, the TLV341AIDBVR delivers tighter DC precision without layout or supply changes; versus OPA316IDBVR, it trades bandwidth and noise for 82% lower quiescent current and integrated shutdown-making it optimal for always-on, battery-limited systems requiring long-term accuracy.

FAQ
What is the maximum supply voltage rating for TLV341AIDBVR?
The absolute maximum supply voltage for TLV341AIDBVR is 5.5 V. Operation above this level risks permanent damage. The recommended operating range is 1.5 V to 5.5 V, making it compatible with 1.8 V, 3.3 V, and 5 V logic domains. TI specifies thermal derating above 4.5 V under high ambient conditions, and 0.1 µF ceramic bypass capacitors are mandatory at the V+ pin to ensure stability.
Does TLV341AIDBVR support true ground-sensing input?
Yes, TLV341AIDBVR supports true ground-sensing input: its common-mode input voltage range extends to –0.2 V (below GND) and up to V+ – 0.5 V. This is enabled by the PMOS input stage and allows direct interfacing with ground-referenced transducers, thermistors, and current-sense shunts without level-shifting circuitry-critical for single-supply systems.
What is the typical output impedance of TLV341AIDBVR in shutdown mode?
In shutdown mode (SHDN = low), TLV341AIDBVR's output enters a high-impedance state with typical leakage of <100 pA. The datasheet confirms the output is actively disabled-not tri-stated via weak pull-ups/downs-so external loading has negligible effect. This allows safe multiplexing or shared-bus configurations without signal contention.
How does the 1.25 mV max input offset voltage of TLV341AIDBVR impact 12-bit ADC interfacing?
At a 3.3 V full-scale ADC range, 1.25 mV offset contributes ≤1.5 LSB error (3.3 V / 4095 ≈ 0.806 mV/LSB). Combined with <1.9 µV/°C drift, this ensures DC accuracy remains within 2 LSB over –40°C to 85°C-enabling direct connection to 12-bit SAR or delta-sigma ADCs without calibration in most portable sensor applications.
Can TLV341AIDBVR drive a 600 Ω audio load directly?
No, TLV341AIDBVR is not rated for continuous 600 Ω loads. Its output short-circuit current is 12 mA (sourcing) and 20 mA (sinking) at 5 V, limiting usable load current to ~5 mA. Driving 600 Ω at ±1 V requires ~3.3 mA, which is within spec-but THD rises to 0.015% at 1 kHz. For line-out, use a dedicated audio driver; for mic preamp or codec interface, TLV341AIDBVR is appropriate with ≥10 kΩ load.
