Product details
Overview
TLV2211IDBVRG4 from Texas Instruments is a single-channel, rail-to-rail output, micropower operational amplifier in SOT-23-5 package. It delivers 21 nV/√Hz input noise at 1 kHz, 1 pA typical input bias current, and 11 µA supply current at 3 V, enabling high-precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLV2211IDBVRG4 datasheet, TLV2211IDBVRG4 pinout, TLV2211IDBVRG4 application, or TLV2211IDBVRG4 equivalent, key selection criteria include its −40°C to 85°C industrial temperature range, rail-to-rail output swing, low-noise performance at micropower supply current, and compatibility with 2.7–10 V single-supply operation for ADC driver and piezoelectric transducer front-end designs.
Technical Context
The TLV2211IDBVRG4 employs Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ) and high input impedance (>10¹² Ω), making it suitable for high-impedance source interfacing. Its rail-to-rail output stage supports full dynamic range utilization across 2.7–10 V supply voltages without requiring split supplies.
It features a gain-bandwidth product of 56 kHz at 3 V and 65 kHz at 5 V, with 56° phase margin into 10 kΩ//100 pF, ensuring stable unity-gain operation. Input common-mode voltage includes the negative rail, and output swing extends within 15 mV of both rails under light load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports direct integration into 3 V and 5 V battery-powered systems without level-shifting. |

Pinout & Package
SOT-23-5 package (DBV): 2.9 mm × 1.6 mm × 1.1 mm body, 5-terminal surface-mount package optimized for minimal PCB area and low parasitic coupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN−) | Inverting Input | Differential input node; placed adjacent to GND to minimize leakage paths in high-impedance applications. |
| 2 (VDD−/GND) | Negative Supply / Ground Reference | Reference node for single-supply operation; internally connected to chip backside for thermal stability. |
| 3 (IN+) | Noninverting Input | High-impedance input; isolated from IN− by GND pin to suppress crosstalk in layout-sensitive circuits. |
| 4 (VDD+) | Positive Supply | Accepts 2.7–10 V; decoupling capacitor placement is simplified by proximity to OUT and IN− pins. |
| 5 (OUT) | Amplifier Output | Rail-to-rail output driving capability; positioned opposite IN− to facilitate compact feedback resistor routing. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA348AIDBVR | Higher GBW (1 MHz), higher supply current (45 µA), same SOT-23-5 package. | Better for AC-coupled, higher-frequency sensor signals; less suitable for multi-year battery life. | Select TLV2211IDBVRG4 when micropower and ultra-low bias current dominate; choose OPA348AIDBVR when bandwidth >100 kHz is required. |
| LPV821DBVR | Lower supply current (650 nA), lower GBW (10 kHz), same rail-to-rail output and −40°C to +125°C rating. | Optimized for ultra-long-life applications (e.g., 10+ year battery); insufficient bandwidth for fast pulse detection. | Choose LPV821DBVR only if sub-µA quiescent current is mandatory and signal bandwidth <5 kHz; TLV2211IDBVRG4 balances noise, speed, and power better for general sensor front-ends. |
Compared with OPA348AIDBVR and LPV821DBVR, the TLV2211IDBVRG4 uniquely delivers 21 nV/√Hz noise at just 11 µA, making it the optimal choice for precision, battery-constrained applications where 50–100 kHz bandwidth suffices and input bias current must stay below 10 pA.

FAQ
What is the operating temperature range for TLV2211IDBVRG4?
The TLV2211IDBVRG4 is rated for industrial operation from −40°C to +85°C. This range is validated per the Absolute Maximum Ratings and Recommended Operating Conditions tables in the official SLOS156E datasheet, supporting deployment in outdoor environmental sensors and automotive cabin modules where ambient temperatures exceed consumer-grade limits.
Does TLV2211IDBVRG4 support rail-to-rail input?
No, the TLV2211IDBVRG4 does not support rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD−) but only up to VDD+ −1.3 V at 3 V supply, as specified in the Recommended Operating Conditions table. The device is explicitly characterized as rail-to-rail *output*, not input.
What is the typical input offset voltage for TLV2211IDBVRG4 at 5 V supply?
The typical input offset voltage for TLV2211IDBVRG4 at 5 V supply and 25°C is 0.45 mV, with a maximum of 3 mV across the full −40°C to +85°C temperature range. This value is confirmed in the Electrical Characteristics table for VDD = 5 V on page 8 of the SLOS156E datasheet.
Can TLV2211IDBVRG4 drive capacitive loads directly?
The TLV2211IDBVRG4 is stable with up to 100 pF capacitive load when configured for unity gain, as verified by 56° phase margin measurements in the Operating Characteristics section (page 7). Driving larger capacitive loads requires isolation resistance or careful compensation per Figure 23 and 24 in the datasheet.
Is TLV2211IDBVRG4 pin-compatible with other SOT-23-5 op-amps?
TLV2211IDBVRG4 follows the standard SOT-23-5 pinout (IN−, GND, IN+, VDD+, OUT), matching industry conventions used by TI's OPAxx and LPVxx families. However, functional compatibility depends on electrical specifications - no official pin-compatible replacement is documented for this specific variant in the datasheet.
