Product details
Overview
TLV2771AIDR from Texas Instruments is a single-channel CMOS rail-to-rail output operational amplifier optimized for precision, low-power, and high-speed signal conditioning in automotive and industrial systems. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage (max), 1 mA supply current per channel, and operates from 2.5 V to 5.5 V single supply - enabling use in ADC driver, sensor front-end, and battery-powered instrumentation.
For engineers reviewing the TLV2771AIDR datasheet, TLV2771AIDR pinout, TLV2771AIDR application, or TLV2771AIDR equivalent, this page provides verified electrical specifications, SOT-23-5 package mapping, temperature-rated performance (−40°C to 125°C), rail-to-rail output drive into 600 Ω with 0.005% THD+N, and validated alternative options for design continuity.
Technical Context
The TLV2771AIDR employs a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage at 10 kHz, supporting high-impedance sensor interfacing. Its rail-to-rail output stage delivers full-swing capability up to ±0.1 V of supply rails under 2.2 mA load, critical for maximizing dynamic range in low-voltage data acquisition.
It features micropower shutdown mode (IDD < 1 µA) and is characterized across −40°C to 125°C, meeting AEC-Q100 stress test requirements for automotive applications. The device lacks internal shutdown control logic in the TLV2771 variant - unlike TLV2770/TLV2773 - confirming it is a non-shutdown single op-amp.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typical - enables accurate reproduction of fast transients in active filters and DAC buffers. |
| Gain-Bandwidth Product | 5.1 MHz typical - supports stable unity-gain operation and closed-loop bandwidth up to ~4.8 MHz with 100-pF load. |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤0.014% gain error in 25-mV full-scale sensor amplification. |
| Supply Current | 1 mA per channel - allows 10+ op-amps on a 10-mA rail in portable diagnostic tools. |
| Input Bias Current | 2 pA typical - minimizes voltage error across >1-MΩ source impedances (e.g., piezoelectric sensors). |

| Operating Temperature | −40°C to 125°C - qualified for engine control unit (ECU) and transmission control module (TCM) environments. |
Pinout & Package
TLV2771AIDR is housed in a 5-pin SOT-23 (DBV) package with moisture sensitivity level 1 (MSL-1), rated for reflow per JEDEC J-STD-020. Pin 1 is marked by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Rail-to-rail output capable of sourcing/sinking ±2.2 mA while maintaining <0.2 V headroom to rails. |
| 2 | IN− | Inverting input - high-impedance CMOS node (10¹² Ω) with 2 pA bias current. |
| 3 | IN+ | Non-inverting input - matched to IN− for optimal common-mode rejection (CMRR ≥60 dB). |
| 4 | GND | Analog ground reference - must be star-connected to minimize noise coupling in mixed-signal PCBs. |
| 5 | VDD | Positive supply input - accepts 2.5 V to 5.5 V; no reverse polarity protection. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 0.1 V of supply rails at 2.2 mA load - maximizes ADC input range in 3.3-V systems. |
| Low distortion into 600 Ω | 0.005% THD+N at 1 kHz - eliminates need for external output filtering in audio and telecom interfaces. |
| Extended temperature range | Specified from −40°C to 125°C - supports placement near powertrain heat sources without derating. |
| High-speed precision | 10.5 V/µs slew rate + 360 µV VIO - enables 12-bit accuracy in 1-µs settling time-critical applications. |
| Low-noise input stage | 17 nV/√Hz at 10 kHz - preserves SNR in front-end amplification of microvolt-level biopotential signals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-channel precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture (0.1 µV/°C drift), lower VIO (10 µV max), but slower slew rate (1.6 V/µs) and higher cost. | Better for DC-critical applications (e.g., weigh scales); unsuitable for >100-kHz signal paths requiring fast settling. | Select when ultra-low drift dominates speed requirements; verify layout immunity to chopper noise artifacts. |
| MCP6001T-E/OT | Lower bandwidth (1 MHz), higher VIO (3 mV max), but wider supply range (1.8–6.0 V) and lower price. | Acceptable for general-purpose 8-bit sensor buffering where precision and speed are secondary. | Choose for cost-sensitive consumer electronics; avoid in automotive or medical designs requiring AEC-Q100 or low-noise specs. |
Compared with TLV2771AIDR, OPA333AIDBVR trades speed and cost for superior DC accuracy, while MCP6001T-E/OT sacrifices bandwidth and offset for broader supply flexibility and lower BOM cost - making TLV2771AIDR the balanced choice for automotive-grade, medium-speed precision signal chains.

FAQ
What is the maximum operating temperature range for TLV2771AIDR?
The TLV2771AIDR is specified from −40°C to 125°C ambient temperature and qualified for automotive applications per AEC-Q100. This range is confirmed in the "recommended operating conditions" table of the SLOS209G datasheet, and applies to the I-suffix grade used in the TLV2771AIDR part number. Operation beyond 125°C risks parametric shift and reliability degradation.
Does TLV2771AIDR include a shutdown pin?
No, TLV2771AIDR does not have a shutdown function. The TLV2771 variant is a single-channel op-amp without enable/shutdown control - unlike TLV2770 (shutdown-capable single) or TLV2773 (dual with shutdown). The SOT-23-5 pinout contains only OUT, IN−, IN+, GND, and VDD terminals, with no dedicated SHDN pin. This is explicitly confirmed in the "TLV277x PACKAGE PINOUTS" section of the datasheet.
What is the typical input bias current of TLV2771AIDR?
The typical input bias current of TLV2771AIDR is 2 pA at 25°C, with a maximum of 100 pA across the full −40°C to 125°C temperature range. This value is measured with RS = 50 Ω and VDD = ±1.35 V (2.7 V total), and is consistent across both C- and I-suffix variants per the electrical characteristics tables in SLOS209G. Such ultra-low IB enables high-impedance sensor interfacing without significant offset error.
Can TLV2771AIDR drive a 600-Ω load with low distortion?
Yes, TLV2771AIDR is specifically characterized for 600-Ω loads: total harmonic distortion plus noise (THD+N) is 0.005% at 1 kHz with AV = 1, RL = 600 Ω, and VDD = 5 V. This performance is guaranteed across the full operating temperature range and confirms suitability for telecom line-driving and audio output stages where spectral purity is critical.
What package type is used for TLV2771AIDR?
TLV2771AIDR uses the 5-pin SOT-23 (DBV) package, as indicated by the "AIDR" suffix per TI's packaging nomenclature and confirmed in the "TLV2770 and TLV2771 AVAILABLE OPTIONS" table. The DBV package has a body size of 2.9 mm × 1.6 mm × 1.1 mm, thermal resistance θJA = 219°C/W, and is RoHS-compliant and halogen-free.
