Product details
Overview
TLV2761IDBVR from Texas Instruments is a single-channel, micropower, rail-to-rail input/output operational amplifier with shutdown, designed for ultra-low-voltage operation (1.8 V to 3.6 V), consuming only 20 μA per channel and featuring 500 kHz bandwidth, 0.20 V/μs slew rate, and 550 μV input offset voltage. It targets battery-powered sensor signal conditioning and portable medical instrumentation where extended battery life and precision at low supply voltage are critical.
For engineers reviewing the TLV2761IDBVR datasheet, TLV2761IDBVR pinout, TLV2761IDBVR application, or TLV2761IDBVR equivalent, this page delivers verified electrical parameters, industrial-grade temperature support (−40°C to 85°C), SOT-23-6 package details, shutdown timing (5 μs turn-on), and real-world application context for low-power analog front-ends.
Technical Context
The TLV2761IDBVR uses CMOS input stage architecture enabling rail-to-rail common-mode input range (−0.2 V to VDD + 0.2 V) and rail-to-rail output swing, essential for maximizing dynamic range at 1.8 V supply. Its micropower design integrates ultralow shutdown current (10 nA/channel) with fast enable/disable timing (5 μs on, 0.8 μs off).
It operates across the full industrial temperature range (−40°C to 85°C), supports split-supply configurations (±0.8 V to ±1.8 V), and maintains stable gain-bandwidth product (500 kHz) and phase margin (63°) under capacitive loads up to 100 pF when properly compensated.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - Enables direct operation from two AA/AAA cells (end-of-life 1.8 V) or NiMH/NiCd (2.4 V nominal) |
| Quiescent Current | 20 μA per channel - Supports multi-year battery life in always-on sensor nodes |
| Shutdown Current | 10 nA per channel - Reduces system standby power by >2000× vs active mode |
| Unity-Gain Bandwidth | 500 kHz - Sufficient for DC–200 Hz biosignal amplification (ECG, pulse oximetry) with margin |
| Slew Rate | 0.20 V/μs - Supports 100 mVpp, 10 kHz signals without distortion in unity-gain buffer |
| Input Offset Voltage | 550 μV (typ) - Enables <0.5% error in 100 mV full-scale sensor interfaces without trimming |
| Input Common-Mode Range | −0.2 V to VDD + 0.2 V - Accepts inputs below ground or above supply, simplifying level-shifting |
Pinout & Package
SOT-23-6 (DBV) package: 2.9 mm × 1.6 mm × 1.15 mm body, surface-mount, tape-and-reel compatible (R-suffix standard). Thermal resistance ΘJA = 294 °C/W, rated for 425 mW power dissipation at TA ≤ 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |

| 4 - VDD | Positive Supply | Single-supply rail (1.8–3.6 V); requires local 0.1 μF ceramic + 6.8 μF tantalum decoupling |

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, wider supply range (2.7–6 V), higher GBW (220 kHz) | Lacks shutdown capability; unsuitable for duty-cycled systems; better for higher-voltage, continuous-operation designs | Select when shutdown is unnecessary and 2.7 V+ supply is available |
| OPA316IDBVR | Lower offset (100 μV), higher GBW (10 MHz), higher supply current (400 μA), no shutdown, 1.8–5.5 V supply | Not micropower; optimized for speed over energy efficiency; incompatible shutdown requirement | Select when precision and bandwidth outweigh battery life concerns |
Compared with TLV2761IDBVR, TLV2451IDBVR offers slightly lower power but no shutdown, while OPA316IDBVR trades 20× higher current for 20× more bandwidth and 5× lower offset-making TLV2761IDBVR uniquely balanced for ultra-low-power, shutdown-capable, 1.8 V sensor interfaces.

FAQ
What is the maximum recommended supply voltage for TLV2761IDBVR?
The absolute maximum supply voltage for TLV2761IDBVR is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V. Exceeding 3.6 V risks parametric degradation and reduced reliability. The device is optimized for low-voltage battery sources-including end-of-life 1.8 V from two alkaline cells-and must not be operated at 5 V or other standard logic rails without regulation.
Does TLV2761IDBVR support rail-to-rail input and output simultaneously?
Yes, TLV2761IDBVR supports true rail-to-rail input and output operation concurrently. Its CMOS input stage allows common-mode voltage from −0.2 V to VDD + 0.2 V, and its output can swing within 25 mV of both rails under 300 kΩ load. This dual rail-to-rail capability is fully characterized and guaranteed across the industrial temperature range (−40°C to 85°C) and entire 1.8–3.6 V supply range.
How does the shutdown function work on TLV2761IDBVR?
The SHDN pin (Pin 5) is an active-low control: pulling it to GND places TLV2761IDBVR into ultralow-power shutdown mode with 10 nA total supply current (per channel), while driving it high (≥2 V at VDD = 2.7–3.6 V) enables normal operation. Turn-on time is 5 μs, turn-off time is 0.8 μs-measured from SHDN edge to IDD reaching 50% of final value. No external pull-up is required; internal logic handles state retention.
What is the typical input offset voltage of TLV2761IDBVR and how does it vary with temperature?
The typical input offset voltage of TLV2761IDBVR is 550 μV at 25°C, with a maximum of 3500 μV over temperature. Its offset voltage drift is specified at 9 μV/°C, meaning over the full industrial range (−40°C to 85°C), total offset variation due to temperature is approximately ±1.1 mV around the room-temperature value-enabling stable DC-coupled operation in uncalibrated sensor interfaces without trimming.
Can TLV2761IDBVR drive capacitive loads, and what is the recommended compensation?
TLV2761IDBVR is stable with capacitive loads up to 10 pF in unity-gain configuration. For loads >10 pF (e.g., ADC input capacitance or long traces), TI recommends adding a series null resistor (RNULL ≥ 20 Ω) between the amplifier output and the load. This isolates the capacitive load from the op-amp's output stage, restoring phase margin to ≥63° and preventing ringing or oscillation-verified in Figure 18 of the datasheet.
