Product details
Overview
TLV341AIDBVT 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 supply current per channel. It operates from 1.5 V to 5.5 V and is used in battery-powered audio preamplifiers and precision supply/battery monitoring circuits.
For engineers reviewing the TLV341AIDBVT datasheet, TLV341AIDBVT pinout, TLV341AIDBVT application, or TLV341AIDBVT equivalent, key selection criteria include ultra-low input bias current (1 pA typ), shutdown current (10 pA typ), rail-to-rail output swing (≤25 mV from rails at 10 kΩ), wide common-mode range (–0.2 V to V+ – 0.5 V), and operation across –40°C to +125°C.
Technical Context
The TLV341AIDBVT employs a PMOS input stage enabling ground-sensing capability and ultra-low input bias current, paired with a CMOS output stage delivering rail-to-rail swing. Its shutdown mode places the output in high-impedance state while reducing supply current to 10 pA typical.
It supports single-supply operation down to 1.5 V with guaranteed functionality up to 5.5 V absolute maximum. The device features 20 nV/√Hz input voltage noise at 10 kHz, 5 µs typical turnon time from shutdown, and JESD22-compliant ESD protection (2000 V HBM, 750 V CDM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct integration into 1.8 V and 3.3 V systems without level-shifting |
| Input Offset Voltage (max) | 1.25 mV at 25°C - ensures ≤1.25 mV DC error in precision sensor signal conditioning |
| Gain Bandwidth Product | 2.3 MHz - supports stable unity-gain buffer or gain-of-10 amplification up to ~230 kHz |
| Supply Current per Channel | 70 µA typical - allows >10-year battery life in always-on 10 µA budget systems |
| Rail-to-Rail Output Swing | ≤25 mV from rails (10 kΩ load) - maximizes dynamic range in low-voltage ADC front-ends |
| Shutdown Current | 10 pA typical - reduces system standby power to negligible levels in portable devices |
| Input Bias Current | 1 pA typical - prevents loading errors in high-impedance pH or photodiode sensor interfaces |
Pinout & Package
SOT-23-6 (DBV) package: 2.90 mm × 1.60 mm body, 0.95 mm height, surface-mount, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Noninverting input | Accepts analog signals from 0 V to V+ – 0.5 V; referenced to GND for single-supply use |
| 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 feedback configuration; same common-mode range as IN+ |
| 4 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; high-impedance during shutdown |
| 5 (SHDN) | Active-low shutdown control | Pulled high (>1.5 V at 1.8 V supply) for normal operation; grounded to disable amplifier |
| 6 (V+) | Positive supply rail | Accepts 1.5–5.5 V; requires local 0.1 µF ceramic bypass capacitor to GND |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input bias current | 1 pA typical - preserves signal integrity in megohm-range sensor interfaces (e.g., electrochemical sensors) |
| A-grade precision offset | 1.25 mV max at 25°C - eliminates need for external trimming in 12-bit ADC applications |
| Rail-to-rail output stage | Swings within 25 mV of V+ and GND - delivers full-scale output for low-voltage microcontrollers and SAR ADCs |
| Fast shutdown recovery | 5 µs typical turnon time - enables rapid wake-up in duty-cycled monitoring systems |
| Extended temperature range | –40°C to +125°C - qualified for under-hood automotive and industrial motor-control sensing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6001T-I/OT | Higher offset (1.5 mV max), no shutdown pin, 1 µA supply current | Lacks shutdown mode; unsuitable for ultra-low-power wake-up architectures | Choose when shutdown is unnecessary and cost is primary constraint |
| OPA316IDBVR | Lower noise (11 nV/√Hz), higher supply current (100 µA), no shutdown | Superior AC performance but 43% higher quiescent draw; no power-gating capability | Prefer for audio line drivers where noise dominates over battery life |
Compared with MCP6001T-I/OT and OPA316IDBVR, TLV341AIDBVT uniquely combines A-grade offset, integrated shutdown, and sub-100 µA supply current-making it optimal for space-constrained, battery-sensitive designs requiring precision and power gating.

FAQ
What is the maximum operating temperature range for TLV341AIDBVT?
The TLV341AIDBVT is rated for operation from –40°C to +125°C ambient temperature. This extended industrial range is validated per TI's characterization and testing protocols and supports deployment in automotive cabin modules, industrial motor drives, and outdoor IoT sensor nodes where thermal extremes occur.
Does TLV341AIDBVT support true rail-to-rail input?
No, TLV341AIDBVT does not support rail-to-rail input. Its common-mode input voltage range extends from –0.2 V to (V+ – 0.5 V), enabling ground-sensing capability but excluding the positive rail. This is confirmed in Section 5.7 and 5.8 of the datasheet under VICR specifications at both 1.8 V and 5 V supplies.
What is the typical turnon time from shutdown for TLV341AIDBVT?
The typical amplifier turnon time from shutdown for TLV341AIDBVT is 5 µs, as specified in Sections 5.9 and 5.10 of the datasheet under t(on) parameter. This value is measured at 25°C with V+ = 1.8 V or 5 V and applies to the transition from SHDN = low to SHDN ≥ V+ threshold.
Can TLV341AIDBVT drive a 600 Ω load?
Yes, TLV341AIDBVT can drive a 600 Ω load, but output swing is reduced: at V+ = 5 V, high-level swing degrades to 20 mV from rail (typical) and low-level to 40 mV (typical). Total harmonic distortion rises to 0.012% at 1 kHz, as shown in Table 5.8 THD specification - acceptable for line-output buffering but not for high-fidelity headphone driving.
Is TLV341AIDBVT pin-compatible with other SOT-23-6 op-amps like LMV321?
No, TLV341AIDBVT is not pin-compatible with LMV321. Pin 5 is SHDN on TLV341AIDBVT but NC on LMV321; pin 2 is GND on TLV341AIDBVT but OUT on LMV321. Layout redesign is required. Always verify pin functions using TI's DBV package drawing and compare against target alternatives' pinouts.
