Product details
Overview
TLV2211CDBVR from Texas Instruments is a single-channel rail-to-rail output operational amplifier in SOT-23-5 package, consuming 11 µA typical supply current at 3 V, featuring 21 nV/√Hz input voltage noise at 1 kHz and 1 pA typical input bias current. It operates from 2.7 V to 10 V and supports common-mode input down to the negative rail - ideal for low-power sensor signal conditioning in battery-powered systems.
For engineers reviewing the TLV2211CDBVR datasheet, TLV2211CDBVR pinout, TLV2211CDBVR application, or TLV2211CDBVR equivalent, key selection criteria include micropower operation (<12 µA), rail-to-rail output swing, ultra-low input bias current (≤1 pA), and guaranteed performance across 0°C to 70°C ambient temperature range.
Technical Context
The TLV2211CDBVR uses Advanced LinCMOS™ process technology to achieve high input impedance (>1012 Ω) and low input bias current while maintaining rail-to-rail output capability. Its input stage accepts common-mode voltages extending to the negative supply rail, enabling direct interfacing with ground-referenced transducers.
It delivers stable unity-gain operation with 56° phase margin into 10 kΩ || 100 pF loads and achieves 7 kHz maximum output-swing bandwidth at AV = 1. The device is fully characterized at 3 V and 5 V, optimized for low-voltage analog front-ends where power budget and dynamic range are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-cell Li-ion, 3.3 V, and 5 V systems without level-shifting. |
| Supply Current (Typ) | 11 µA at 3 V - enables >1-year battery life in coin-cell–powered IoT sensors. |
| Input Bias Current (Typ) | 1 pA - minimizes voltage error in high-impedance piezoelectric or pH electrode interfaces. |
| Input Voltage Noise | 21 nV/√Hz at 1 kHz - preserves SNR in low-level signal amplification (e.g., medical ECG front-end). |
| Output Swing | Rail-to-rail - delivers full 0 V to VDD dynamic range, maximizing ADC utilization in single-supply data acquisition. |
| Input Offset Voltage (Max) | 3 mV - ensures ≤0.3% gain error in 1 V full-scale instrumentation amplifier configurations. |
| Common-Mode Input Range | Includes negative rail - allows direct connection of grounded-source sensors without biasing resistors. |
Pinout & Package
SOT-23-5 package (DBV): 2.9 mm × 1.6 mm × 1.1 mm body, 0.95 mm pitch, tape-and-reel compatible. Pin 2 internally connected to die backside (GND reference).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN−) | Inverting input | Accepts feedback network; placed adjacent to OUT (Pin 5) to minimize parasitic loop area in PCB layout. |
| 2 (VDD−/GND) | Negative supply / ground reference | Internally bonded to chip backside; serves as primary GND return path for input stage and output stage. |
| 3 (IN+) | Non-inverting input | Separated from IN− by GND (Pin 2) to suppress coupling; optimal for high-EMI environments. |
| 4 (VDD+) | Positive supply | Accepts 2.7–10 V; decoupling capacitor recommended within 2 mm of this pin for stability. |
| 5 (OUT) | Amplifier output | Rail-to-rail capable; drives 10 kΩ load to within 15 mV of rails at 3 V supply. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers full 0 V to VDD swing - eliminates need for dual supplies in ADC driver stages. |
| Ultra-low input bias current | 1 pA typical - reduces leakage-induced offset in photodiode transimpedance amplifiers. |
| Micropower operation | 11 µA supply current - enables continuous sensing in energy-harvesting nodes with <10 µW average power budgets. |
| Low-noise performance | 21 nV/√Hz at 1 kHz - outperforms competing SOT-23 op-amps by 5× in noise-sensitive applications. |
| Optimized SOT-23 pinout | GND between inputs + OUT adjacent to IN− - simplifies layout and reduces board-level noise pickup. |

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 supply current (48 µA typ), lower noise (11 nV/√Hz), same SOT-23-5 package. | Better SNR but 4.4× higher quiescent power - unsuitable for multi-year battery life requirements. | Select when noise dominates over power; avoid when <15 µA total system budget is mandatory. |
| MCP6001T-E/OT | Lower supply current (9 µA typ), higher input bias current (100 pA typ), same rail-to-rail output. | 100× higher input bias degrades accuracy with >1 MΩ source impedances; suitable only for buffered sensor outputs. | Select for cost-sensitive, low-precision applications with low-Z sources; avoid for piezoelectric or pH electrodes. |
Compared with OPA348AIDBVR and MCP6001T-E/OT, the TLV2211CDBVR uniquely balances ultra-low input bias (1 pA), micropower consumption (11 µA), and rail-to-rail output in a space-constrained SOT-23-5 footprint - making it the only viable option for long-life, high-impedance sensor interfaces requiring sub-µA-level leakage control.

FAQ
What is the operating temperature range for the TLV2211CDBVR?
The TLV2211CDBVR is rated for operation from 0°C to 70°C ambient temperature. This commercial-grade specification is confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official datasheet (SLOS156E). The "C" suffix explicitly denotes the 0°C to 70°C grade, distinct from the "I" grade (−40°C to 85°C). Designers must ensure thermal management maintains junction temperature within limits under full load.
Does the TLV2211CDBVR support rail-to-rail input?
No, the TLV2211CDBVR 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 and VDD+ −1.3 V at 5 V supply. This is explicitly stated in the Recommended Operating Conditions table. While the output swings rail-to-rail, the input stage requires headroom above the positive rail - a key distinction from true rail-to-rail input/output op-amps.
What is the typical input offset voltage for TLV2211CDBVR at 3 V supply?
The typical input offset voltage for TLV2211CDBVR at 3 V supply and 25°C is 0.47 mV, with a maximum of 3 mV across the full 0°C to 70°C operating range. This value is specified in the Electrical Characteristics table for VDD = 3 V and applies to the "C" grade. The offset remains stable across supply voltage variations, with no significant drift observed between 2.7 V and 10 V operation.
Can TLV2211CDBVR drive capacitive loads directly?
The TLV2211CDBVR is stable with up to 100 pF capacitive load when driving a 10 kΩ resistive load, as verified by 56° phase margin measurements in the Typical Characteristics section (Figure 23). Driving larger capacitive loads (e.g., >200 pF) or purely capacitive loads without series resistance may cause peaking or oscillation. For ADC input buffering, a 10 Ω to 50 Ω isolation resistor is recommended between TLV2211CDBVR output and sampling capacitor.
Is TLV2211CDBVR pin-compatible with other SOT-23-5 op-amps like MCP6001?
No, TLV2211CDBVR is not pin-compatible with MCP6001T-E/OT despite sharing the SOT-23-5 package. The pin assignments differ: TLV2211CDBVR uses Pin 1 = IN−, Pin 2 = GND, Pin 3 = IN+, Pin 4 = VDD+, Pin 5 = OUT; MCP6001 uses Pin 1 = OUT, Pin 2 = IN−, Pin 3 = IN+, Pin 4 = VDD+, Pin 5 = GND. Swapping these parts without PCB revision will result in incorrect connections and functional failure.
