Product details
Overview
TLV341IDBVT from Texas Instruments is a single, low-voltage, rail-to-rail output CMOS operational amplifier with active-low shutdown control, designed for 1.5V–5.5V single-supply operation. It delivers 2.3MHz gain bandwidth, 0.9V/μs slew rate, 70μA/channel supply current, and 1.25mV max input offset voltage (A grade, 25°C), enabling precision signal conditioning in space-constrained battery-powered systems such as portable audio preamplifiers and supply current monitors.
For engineers reviewing the TLV341IDBVT datasheet, TLV341IDBVT pinout, TLV341IDBVT application, or TLV341IDBVT equivalent, key selection considerations include its 6-pin SOT-23 (DBV) package, shutdown current of 10pA (typ), rail-to-rail output swing within 20mV of rails (RL = 10kΩ), –40°C to 125°C operating range, and PMOS input stage enabling ground-sensing capability.
Technical Context
The TLV341IDBVT employs a PMOS input stage that extends the common-mode input range down to ground (–0.2V) and up to V+ – 0.5V, supporting direct-coupled, low-voltage sensor interfaces. Its CMOS output stage enables true rail-to-rail swing with <25mV headroom at both rails under 10kΩ load.
Shutdown functionality is implemented via an active-low SHDN pin; asserting it to GND reduces supply current to ≤1μA (typ) and places the output in high-impedance state, with 5μs typical turn-on time. The device maintains stable operation across 1.5V–5.5V supply and full industrial temperature range without phase reversal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5V to 5.5V - supports direct integration into Li-ion, coin-cell, and USB-powered systems without level-shifting. |
| Gain Bandwidth Product | 2.3MHz (typ) - enables stable unity-gain buffer and closed-loop amplification up to ~200kHz with 60° phase margin. |
| Input Offset Voltage | 1.25mV max (A grade, 25°C) - ensures ≤0.25% error in 500mV full-scale DC-coupled measurement paths. |
| Supply Current per Channel | 70μA (typ) - allows >10-year battery life in always-on monitoring circuits powered by CR2032 cells. |
| Output Swing (RL = 10kΩ) | Within 7mV of V+ and 14mV of GND - preserves dynamic range in 1.8V ADC front-ends and low-voltage analog signal chains. |
| Input Bias Current | 1pA (typ) - minimizes voltage error across high-impedance sources (e.g., pH electrodes, photodiode transimpedance feedback). |
| Shutdown Current | 10pA (typ) - reduces system standby power to sub-nW levels when amplifier is inactive. |
Pinout & Package
TLV341IDBVT is packaged in a 6-pin SOT-23 (DBV) case measuring 2.90mm × 1.60mm, optimized for high-density PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Noninverting input | Accepts input signals from 0V to V+ – 0.5V; PMOS input enables ground-referenced sensing. |
| 2 (GND) | Ground reference | Primary return path for supply and signal currents; must be low-impedance for noise immunity. |
| 3 (IN−) | Inverting input | Drives feedback network; matched to IN+ for precision differential operation. |
| 4 (OUT) | Amplifier output | Rail-to-rail CMOS output capable of sourcing/sinking ≥6mA; high-Z in shutdown mode. |
| 5 (SHDN) | Active-low shutdown control | Pulled high (≥1.5V at 1.8V supply) for normal operation; driven low to enter ultra-low-power state. |
| 6 (V+) | Positive supply rail | Accepts 1.5V–5.5V; requires local 0.1μF ceramic bypass capacitor 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 |
|---|---|---|---|
| TLV341AIDBVT | Guarantees 1.25mV max VIO at 25°C vs. standard TLV341IDBVT's 4mV max; otherwise identical specs and pinout. | Suitable where initial DC accuracy is critical (e.g., factory-calibrated medical sensors), not required for AC-coupled or auto-zeroed systems. | Select TLV341AIDBVT when VIO budget is ≤1.25mV at room temperature; TLV341IDBVT suffices for cost-sensitive designs with calibration or higher-temp operation. |
| OPA316IDBVR | Higher 10MHz GBW, 6.5V/μs slew rate, but 100μA supply current and no shutdown; same SOT-23-6 package. | Better for wideband signal acquisition (e.g., ultrasonic pulse detection), unsuitable for ultra-low-power shutdown use cases. | Choose OPA316IDBVR when bandwidth >2.3MHz is mandatory and shutdown is unnecessary; TLV341IDBVT remains optimal for battery life and power gating. |
Compared with TLV341AIDBVT, the TLV341IDBVT trades guaranteed low offset for lower cost, while versus OPA316IDBVR it prioritizes micropower shutdown capability over speed-making it uniquely suited for duty-cycled, energy-constrained sensing nodes.

FAQ
What is the maximum supply voltage rating for TLV341IDBVT?
The absolute maximum supply voltage for TLV341IDBVT is 5.5V. Operation above this level risks permanent damage. Recommended operating range is 1.5V to 5.5V, with full electrical specifications guaranteed across this span. At 5V supply, the device achieves 2.3MHz GBW, 1V/μs slew rate, and 1.25mV max VIO (A grade), making TLV341IDBVT compatible with standard 5V logic and mixed-signal systems.
Does TLV341IDBVT support true rail-to-rail input common-mode range?
TLV341IDBVT features a PMOS input stage enabling common-mode input down to –0.2V (below ground) and up to V+ – 0.5V. While not fully rail-to-rail on the upper end, this range includes ground and supports direct coupling of 0V-referenced sensors. Input offset voltage remains stable across this range, and TLV341IDBVT exhibits no phase reversal-critical for precision instrumentation where input signals may cross rail boundaries.
How does the shutdown function operate on TLV341IDBVT?
TLV341IDBVT enters shutdown when the SHDN pin is pulled low (≤0.2V). In this state, supply current drops to ≤1μA (typ), and the output becomes high-impedance. Normal operation resumes within 5μs after SHDN rises to ≥1.5V (at 1.8V supply) or ≥4.5V (at 5V supply). This fast wake-up enables burst-mode sensing in TLV341IDBVT-based data loggers without sacrificing responsiveness.
What is the thermal resistance of TLV341IDBVT in its SOT-23 package?
For the TLV341IDBVT in the DBV (SOT-23-6) package, the junction-to-ambient thermal resistance (RθJA) is 193.4°C/W. This value assumes standard JEDEC 2-layer board conditions. With a maximum ambient temperature of 125°C and 70μA supply current, self-heating is negligible (<0.1°C rise), confirming TLV341IDBVT's suitability for thermally constrained enclosures without heatsinking.
Can TLV341IDBVT drive a 600Ω load effectively?
TLV341IDBVT specifies ±6mA output current (sourcing/sinking) and maintains 0.012% THD+N into 600Ω at 1kHz with 5V supply. While optimized for high-impedance loads (≥10kΩ), it can drive 600Ω with acceptable distortion for short-duration audio bursts. For continuous 600Ω operation, verify thermal dissipation and consider buffering; TLV341IDBVT's primary strength lies in precision, low-power signal conditioning-not line driving.
