Product details
Overview
TLV2761IDBVT from Texas Instruments is a single-channel, micropower, rail-to-rail input/output operational amplifier with shutdown, operating from 1.8 V to 3.6 V supply. It delivers 500 kHz bandwidth and 0.20 V/μs slew rate at only 20 μA supply current per channel, with 10 nA shutdown current and 550 μV input offset voltage - optimized for ultra-low-power sensor signal conditioning in battery-powered industrial and portable instrumentation.
For engineers reviewing the TLV2761IDBVT datasheet, TLV2761IDBVT pinout, TLV2761IDBVT application, or TLV2761IDBVT equivalent, key selection criteria include its SOT-23-6 package, guaranteed −40°C to +85°C operation, rail-to-rail I/O swing at 1.8 V, and precise shutdown control with 5 μs turn-on time - critical for energy-constrained measurement systems requiring long battery life and stable DC performance.
Technical Context
The TLV2761IDBVT uses CMOS input stage architecture enabling rail-to-rail common-mode input range (−0.2 V to VDD + 0.2 V) and ultralow input bias current (3 pA typical). Its internal shutdown logic disables the output stage while maintaining <10 nA per-channel quiescent current, preserving system-level power integrity during sleep cycles.
Designed for single-supply operation down to 1.8 V, it supports direct interfacing with low-voltage ADCs and microcontrollers without level-shifting. The device exhibits 95 nV/√Hz input voltage noise and maintains ≥63° phase margin into 100 pF loads - enabling stable unity-gain buffer configurations in compact analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - compatible with two AA/AAA cells (end-of-life 1.8 V) or NiMH/NiCd (2.4 V nominal) |
| Quiescent Current | 20 μA per channel - enables multi-year battery life in always-on sensor nodes |
| Shutdown Current | 10 nA per channel - reduces standby power by >2000× vs active mode |
| Input Offset Voltage | 550 μV max at 25°C - ensures ≤1 mV error in 12-bit 3.3 V ADC interfaces |
| Unity-Gain Bandwidth | 500 kHz - supports anti-aliasing filtering and low-frequency sensor amplification up to ~100 kHz |
| Slew Rate | 0.20 V/μs - sufficient for 100 kHz full-scale sine wave output at 2 Vpp |
| Input Common-Mode Range | −0.2 V to VDD + 0.2 V - accepts signals below ground and up to rail+200 mV for true rail-to-rail sensing |
Pinout & Package
TLV2761IDBVT is housed in a 6-pin SOT-23 (DBV) package with exposed pad for thermal enhancement and standard tape-and-reel delivery (3,000 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 - IN+ | Noninverting Input | High-impedance input accepting signals from −0.2 V to VDD + 0.2 V without clipping |
| 3 - OUT | Amplifier Output | Rail-to-rail output capable of sourcing/sinking ±5 mA; drives 300 kΩ load to within 25 mV of rails at 1.8 V |
| 4 - GND | Analog Ground Reference | Primary return path for input/output currents; must be connected to low-impedance ground plane |
| 5 - SHDN | Active-High Shutdown Control | Logic-compatible input; ≥2 V (VDD ≥ 2.7 V) enables operation; ≤0.6 V disables amplifier with 10 nA IDD(SHDN) |
| 6 - VDD | Positive Supply Rail | Single supply input; requires local 0.1 μF ceramic + 6.8 μF tantalum decoupling per TI layout guidelines |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2451IDBVR | Higher supply current (23 μA), no shutdown, 0.11 V/μs slew rate, 2.7–6 V operation | Lacks shutdown capability and 1.8 V compatibility; suited for higher-voltage, non-battery systems | Select when 2.7 V minimum supply is acceptable and shutdown is unnecessary |
| OPA316IDBVR | Lower VIO (100 μV typ), 1 MHz GBW, 1.8–5.5 V, 100 μA IQ, no shutdown | Higher power, no shutdown, better DC precision but incompatible with ultra-low-power sleep modes | Select when higher speed and lower offset outweigh micropower requirements |
Compared with TLV2761IDBVT, TLV2451IDBVR offers slightly higher supply current but no shutdown or 1.8 V support, while OPA316IDBVR trades 5× higher IQ for improved AC/DC performance - making TLV2761IDBVT uniquely suited for sub-20 μA, 1.8 V, shutdown-enabled designs.

FAQ
What is the maximum recommended supply voltage for TLV2761IDBVT?
The absolute maximum supply voltage for TLV2761IDBVT is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V per TI SLOS326F datasheet. Exceeding 3.6 V risks parametric degradation and reduced reliability, especially at elevated temperatures. For dual-cell alkaline operation, 1.8 V represents end-of-life voltage; 2.4 V reflects nominal NiMH/NiCd voltage.
Does TLV2761IDBVT support rail-to-rail input at 1.8 V supply?
Yes, TLV2761IDBVT supports rail-to-rail input with a common-mode voltage range of −0.2 V to VDD + 0.2 V at 1.8 V supply. This allows direct interface with signals referenced to ground or pulled slightly below ground (e.g., thermocouple outputs), and accommodates inputs up to 2.0 V - essential for maximizing dynamic range in low-voltage data acquisition systems.
What is the typical turn-on time for TLV2761IDBVT shutdown mode?
The typical amplifier turn-on time (ton) for TLV2761IDBVT is 5 μs, defined as the interval between SHDN rising to valid high level and supply current reaching 50% of final value. This fast wake-up enables rapid sampling bursts in duty-cycled sensor systems without sacrificing micropower benefits during idle periods.
Can TLV2761IDBVT drive capacitive loads without instability?
TLV2761IDBVT maintains ≥63° phase margin into 100 pF loads per datasheet Figure 18, but for capacitive loads >10 pF, TI recommends adding a series nulling resistor (RNULL ≥20 Ω) between output and load. This isolates the amplifier's output impedance from the capacitive reactance, preventing peaking or oscillation in precision buffering applications.
Is TLV2761IDBVT qualified for industrial temperature range?
Yes, TLV2761IDBVT carries the 'I' suffix indicating qualification over −40°C to +85°C free-air temperature range. Electrical characteristics including input offset voltage (6800 μV max), supply current (≤30 μA), and output drive capability are fully specified across this range - making it suitable for deployment in uncontrolled industrial environments such as factory floor sensors and outdoor utility meters.
