Product details
Overview
TLV2211IDBVTG4 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 voltage noise at 1 kHz, 1 pA typical input bias current, and 11 µA supply current at 3 V - optimized for battery-powered signal conditioning of high-impedance sources like piezoelectric transducers.
For engineers reviewing the TLV2211IDBVTG4 datasheet, TLV2211IDBVTG4 pinout, TLV2211IDBVTG4 application, or TLV2211IDBVTG4 equivalent, key selection criteria include its −40°C to +85°C industrial temperature range, rail-to-rail output swing (enabling full dynamic range with 3-V ADCs), low-noise performance below 22 nV/√Hz, and validated SOT-23 layout compatibility for space-constrained sensing nodes.
Technical Context
The TLV2211IDBVTG4 uses Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ) and rail-to-rail output swing - critical for interfacing with low-leakage sensors and single-supply ADCs. Its common-mode input voltage range extends to the negative rail, supporting ground-referenced signal acquisition.
It features a 56 kHz gain-bandwidth product and 0.005 V/µs slew rate at unity gain with 100-pF load, ensuring stable operation in low-frequency precision amplification. Phase margin is fixed at 56°, enabling robust closed-loop performance without external compensation in standard configurations.
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 or low-voltage rail systems without level-shifting. |
| Input Bias Current | 1 pA typ - enables accurate amplification of signals from ultra-high-impedance sources (e.g., >1 GΩ piezo sensors) without significant DC error. |
| Input Voltage Noise | 21 nV/√Hz at 1 kHz - ensures minimal added noise in low-level analog front-ends for medical or environmental sensing. |
| Output Swing | Rail-to-rail - delivers full 0 V to VDD output range, maximizing SNR when driving 3-V SAR or delta-sigma ADCs. |
| Quiescent Current | 11 µA per channel at 3 V - allows multi-year operation on coin-cell batteries in wireless sensor nodes. |
| Input Offset Voltage | 0.47 mV max at 25°C - provides ≤0.5-mV DC error in precision DC-coupled gain stages without trimming. |
| Common-Mode Input Range | Includes negative rail (VDD−) - permits true ground-sensing in single-supply configurations (e.g., current shunt monitoring). |
Pinout & Package
SOT-23-5 package (DBV), 2.9 mm × 1.6 mm footprint, 5-pin surface-mount device with exposed pad not present - compatible with standard reflow profiles and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN−) | Inverting Input | Differential input node; placed adjacent to OUT for compact feedback routing and minimized parasitic capacitance. |
| 2 (VDD−/GND) | Negative Supply / Ground Reference | Reference terminal for single-supply operation; internally tied to substrate backside for thermal stability. |
| 3 (IN+) | Non-inverting Input | High-impedance input node; isolated from IN− by GND pin to suppress coupling in noisy PCB environments. |
| 4 (VDD+) | Positive Supply | Power input; decoupling capacitor must be placed within 2 mm to maintain PSRR >80 dB across 10 Hz–100 kHz. |
| 5 (OUT) | Amplifier Output | Rail-to-rail voltage source; capable of sourcing/sinking ±100 µA while maintaining <150 mV saturation at 3 V. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers 0 V to VDD swing at 3 V supply - eliminates need for dual supplies when interfacing with 3-V ADCs or microcontroller ADC inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA316IDBVR | Higher GBW (10 MHz vs 56 kHz), higher supply current (400 µA), same SOT-23-5 package. | Better suited for active filters or higher-speed sensor interfaces; not viable for multi-year battery operation. | Select TLV2211IDBVTG4 when micropower and low-noise at DC–10 kHz dominate; choose OPA316IDBVR only if bandwidth >100 kHz is required. |
| LPV821DBVR | Lower supply current (650 nA), lower GBW (10 kHz), same rail-to-rail output and 1-pA input bias. | Optimized for ultra-long-life applications (e.g., 10+ year utility metering); sacrifices bandwidth and output drive capability. | Prefer TLV2211IDBVTG4 when 56-kHz GBW and ±100-µA output drive are needed; LPV821DBVR fits only ultra-low-frequency, ultra-low-power niches. |
Compared with OPA316IDBVR and LPV821DBVR, the TLV2211IDBVTG4 uniquely balances sub-22-nV/√Hz noise, 11-µA quiescent current, and 56-kHz bandwidth - making it the optimal choice for battery-powered precision sensing where both noise and power are constrained but moderate speed is still required.

FAQ
What is the maximum operating temperature range for the TLV2211IDBVTG4?
The TLV2211IDBVTG4 is rated for an industrial operating free-air temperature range of −40°C to +85°C, as confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official SLOS156E datasheet. This range is validated across all electrical specifications including input offset voltage, CMRR, and supply current.
Does the TLV2211IDBVTG4 support rail-to-rail input operation?
No, the TLV2211IDBVTG4 does not support rail-to-rail input operation. Its common-mode input voltage range extends to the negative rail (VDD−) but only up to VDD+ − 1.3 V at 3 V supply - meaning the maximum allowable common-mode voltage is 1.7 V. Full rail-to-rail input capability is not specified or guaranteed for the TLV2211IDBVTG4.
Can the TLV2211IDBVTG4 drive a 10-kΩ load while maintaining rail-to-rail output swing?
Yes, the TLV2211IDBVTG4 maintains rail-to-rail output swing into a 10-kΩ load at 3 V supply, delivering ≥2.94 V high-level output and ≤15 mV low-level output (per Electrical Characteristics table, VDD = 3 V, TA = 25°C). This is verified under standard test conditions with no additional series resistance or capacitive loading.
What is the typical input offset voltage drift over temperature for the TLV2211IDBVTG4?
The TLV2211IDBVTG4 has a typical input offset voltage temperature coefficient (αVIO) of 1 µV/°C across its full operating range (−40°C to +85°C), as documented in the Electrical Characteristics table for the TLV2211I grade. This results in ≤126 µV total drift across the full temperature span, contributing predictably to system-level DC error budgets.
Is the TLV2211IDBVTG4 pin-compatible with other SOT-23-5 op-amps such as the TLV2371 or MCP6001?
No, the TLV2211IDBVTG4 is not pin-compatible with TLV2371 or MCP6001. While all three use SOT-23-5 packages, the TLV2211IDBVTG4 pinout is IN− (1), GND (2), IN+ (3), VDD+ (4), OUT (5); TLV2371 uses IN− (1), IN+ (2), VDD+ (3), OUT (4), GND (5); MCP6001 uses VDD+ (1), IN+ (2), IN− (3), OUT (4), GND (5). Direct replacement requires PCB redesign.
