Product details
Overview
TLV2211IDBVT 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 TLV2211IDBVT datasheet, TLV2211IDBVT pinout, TLV2211IDBVT application, or TLV2211IDBVT equivalent, key selection criteria include its −40°C to 85°C industrial temperature range, rail-to-rail output swing (enabling full dynamic range with 2.7–10 V supplies), and ultra-low power consumption without sacrificing CMRR (83 dB) or open-loop gain (7 V/mV @ 3 V).
Technical Context
The TLV2211IDBVT 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 down to the negative rail, supporting single-supply operation with ground-referenced sensors.
It features internal compensation for unity-gain stability with capacitive loads up to 100 pF, delivering 7 kHz maximum output-swing bandwidth and 56° phase margin. The device is fully characterized at both 3 V and 5 V, with guaranteed performance across its full industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports direct integration into 3.3 V and 5 V systems, plus extended battery operation down to 2.7 V. |
| Input Bias Current | 1 pA typ - enables accurate amplification of signals from ultra-high-impedance sources (e.g., pH electrodes, photodiodes). |
| Input Voltage Noise | 21 nV/√Hz @ 1 kHz - 5× lower than competitive SOT-23 micropower op-amps, critical for low-level sensor signal integrity. |
| Output Swing | Rail-to-rail - delivers full-scale output (e.g., 0–2.94 V on 3 V supply) without headroom loss, maximizing ADC utilization. |
| Quiescent Current | 11 µA typ @ 3 V - extends battery life in portable monitoring devices beyond 10 years in sleep-mode-cycled applications. |
| Common-Mode Input Range | Includes negative rail (VDD−) - allows direct interface with ground-referenced transducers and single-ended sensors. |
| CMRR | 83 dB min @ 25°C - rejects power supply and shared-ground noise in noisy industrial environments. |
Pinout & Package
SOT-23-5 package (DBV), 5-pin surface-mount, 2.9 mm × 1.6 mm footprint - occupies one-third the board area of SOIC-8, enabling placement adjacent to signal sources to minimize PCB trace noise pickup.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN−) | Inverting input | High-impedance node for feedback network connection; isolated from IN+ by GND pin to prevent coupling. |
| 2 (VDD−/GND) | Negative supply / Ground reference | Primary ground return path; internally connected to chip backside for thermal and EMI control. |
| 3 (IN+) | Non-inverting input | High-impedance sensor interface point; separated from IN− by GND pin to suppress leakage paths. |
| 4 (VDD+) | Positive supply | Accepts 2.7–10 V; decoupling capacitor must be placed adjacent to this pin per layout guidelines. |
| 5 (OUT) | Amplifier output | Rail-to-rail capable; positioned adjacent to IN− to simplify negative feedback routing and reduce parasitic inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers >98% of supply rail-to-rail range (e.g., 0.015 V to 2.94 V on 3 V), preserving full ADC input dynamic range. |
| Ultra-low input bias current | 1 pA typ ensures <1 µV error from 1 GΩ source impedance - essential for precision piezoelectric and electrochemical sensing. |
| Low-noise architecture | 21 nV/√Hz @ 1 kHz enables detection of sub-mV signals without external filtering or gain-stage noise amplification. |
| Wide supply range | Operates from 2.7 V to 10 V - eliminates need for LDOs in multi-battery or wide-input industrial power rails. |
| Industrial temperature grade | Specified from −40°C to +85°C - qualified for deployment in outdoor remote sensors and factory-floor instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture; 0.1 µV/°C offset drift vs TLV2211IDBVT's 0.5 µV/°C; higher 17 µA supply current. | Better DC accuracy over temperature; less suitable for ultra-low-power battery life-critical designs. | Select OPA333AIDBVR when long-term offset stability dominates over quiescent current. |
| MCP6001T-E/OT | Higher 100 nV/√Hz noise; 100 µA supply current; same SOT-23-5 package and rail-to-rail output. | Lower cost; adequate for non-critical signal chains where noise and battery life are secondary. | Select MCP6001T-E/OT for cost-sensitive industrial controls where 21 nV/√Hz noise is not required. |
Compared with OPA333AIDBVR and MCP6001T-E/OT, the TLV2211IDBVT uniquely balances ultra-low power (11 µA), low noise (21 nV/√Hz), and rail-to-rail output in an industrial-grade SOT-23-5 package - making it optimal for battery-powered precision sensing where both accuracy and energy efficiency are mandatory.

FAQ
What is the operating temperature range of the TLV2211IDBVT?
The TLV2211IDBVT is rated for industrial operation from −40°C to +85°C. This range is validated across all key parameters including input offset voltage, CMRR, and supply current - ensuring reliable performance in outdoor sensor nodes, factory automation equipment, and portable medical devices exposed to ambient thermal extremes. The 'I' suffix in TLV2211IDBVT explicitly denotes this industrial temperature grade.
Does the TLV2211IDBVT support true rail-to-rail input?
No, the TLV2211IDBVT does not feature 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 - meaning it accepts inputs from ground to 1.7 V. However, its rail-to-rail *output* (0.015 V to 2.94 V on 3 V) remains fully functional, making it ideal for single-supply sensor buffering where the input signal stays near ground.
Can the TLV2211IDBVT drive capacitive loads?
Yes, the TLV2211IDBVT is unity-gain stable with capacitive loads up to 100 pF, as confirmed by phase margin measurements of 56° under those conditions. For loads exceeding 100 pF, external isolation resistance (e.g., 10–50 Ω in series with the output) is recommended to maintain stability. This capability supports direct connection to ADC input capacitors and long PCB traces without oscillation risk.
What is the typical supply current of the TLV2211IDBVT at 5 V?
The TLV2211IDBVT draws 13 µA typical supply current at 5 V and 25°C, as specified in the Electrical Characteristics table for VDD = 5 V. This value increases slightly across temperature and process variation but remains below 30 µA over the full −40°C to +85°C range - confirming its classification as a micropower amplifier suitable for decade-long battery operation in low-duty-cycle sensing applications.
Is the TLV2211IDBVT pin-compatible with other SOT-23-5 op-amps?
The TLV2211IDBVT follows the industry-standard SOT-23-5 pinout (IN−, GND, IN+, VDD+, OUT), matching TI's own TLV2371 and many third-party micropower op-amps. However, electrical compatibility requires verification of input/output voltage ranges, supply current, and stability characteristics - as pinout alignment alone does not guarantee drop-in replacement. Always validate loop stability and DC accuracy in the target application.
