Product details
Overview
TLV2772IDR from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for precision, low-power, single-supply operation. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, and 1 mA per-channel supply current across 2.5 V to 5.5 V supply range - enabling high-fidelity signal conditioning in battery-powered data acquisition and sensor front-ends.
For engineers reviewing the TLV2772IDR datasheet, TLV2772IDR pinout, TLV2772IDR application, or TLV2772IDR equivalent, key selection criteria include its rail-to-rail output swing into 600-Ω loads (0.005% THD+N), −40°C to 125°C automotive-grade temperature rating, and compatibility with ADC reference buffering and portable medical instrumentation.
Technical Context
The TLV2772IDR employs a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, supporting high-impedance sensor interfacing without significant DC error or noise degradation. Its unity-gain-stable architecture achieves 46° phase margin with 600-Ω load and 100-pF capacitive load, ensuring robust closed-loop performance in filtering and driving applications.
It features full rail-to-rail output swing (within 100 mV of rails at 2.2 mA) and operates down to 2.5 V supply, making it suitable for direct interface with 3.3-V and 2.7-V microcontrollers and successive-approximation ADCs. The device is characterized across extended temperature and supply ranges, with guaranteed performance at both 2.7 V and 5 V.
Key Specifications

Pinout & Package
TLV2772IDR is supplied in an 8-pin SOIC (Small Outline Integrated Circuit) package (package code "D"), measuring 6.0 mm × 4.9 mm × 1.75 mm, with standard 1.27-mm lead pitch and gull-wing leads. It is RoHS-compliant and rated for surface-mount reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | High-impedance differential input node; referenced to common-mode voltage range GND to VDD − 1.3 V |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 2 µV max offset, 0.02 µV/°C drift vs. TLV2772IDR's 360 µV and 2 µV/°C | Better DC precision for long-term sensor monitoring; higher cost and 17 µA per-channel current | Select OPA2333AIDR only when sub-10 µV offset stability is mandatory; TLV2772IDR preferred for cost-sensitive, low-power designs |
| MCP6022-I/SN | Lower bandwidth (10 MHz), higher supply current (1.1 mA), no specified THD+N; 1.8–5.5 V supply range | Compatible for general-purpose dual op-amp use but lacks verified 600-Ω linearity and automotive temp grade | MCP6022-I/SN suits commercial-grade consumer electronics; TLV2772IDR remains optimal for automotive and telecom where THD+N and temp range are critical |
Compared with OPA2333AIDR and MCP6022-I/SN, TLV2772IDR uniquely balances 5.1-MHz bandwidth, 0.005% THD+N into 600 Ω, and −40°C to 125°C qualification - making it the most cost-effective dual op-amp for automotive sensor signal chains requiring both speed and fidelity.

FAQ
What is the maximum operating supply voltage for TLV2772IDR?
The absolute maximum supply voltage for TLV2772IDR is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation above 5.5 V risks permanent damage, while operation below 2.5 V may cause degraded slew rate, bandwidth, and output swing. All electrical specifications in the datasheet are guaranteed within the 2.5–5.5 V range, including at 2.7 V and 5 V test points.
Does TLV2772IDR support rail-to-rail input?
No, TLV2772IDR does not support rail-to-rail input. Its common-mode input voltage range is specified as GND to VDD − 1.3 V (e.g., 0 V to 3.7 V at VDD = 5 V). This limitation arises from its CMOS input stage topology. However, it does provide true rail-to-rail output swing - delivering voltages within 100 mV of either rail under 2.2-mA load - which is explicitly confirmed in the datasheet's VOH/VOL tables.
Is TLV2772IDR qualified for automotive applications?
Yes, TLV2772IDR carries the "I" temperature suffix (−40°C to +125°C) and is explicitly designated as Q-Temp Automotive in TI documentation. It meets AEC-Q100 stress testing requirements for automotive electronics and is used in engine control, battery monitoring, and ADAS sensor signal chains. The "IDR" part number denotes the 8-pin SOIC package with automotive-grade screening and traceability.
What is the shutdown current of TLV2772IDR?
TLV2772IDR does not include a shutdown pin or function. Unlike TLV2770/TLV2773/TLV2775 variants, the TLV2772 family (including TLV2772IDR) has no integrated shutdown circuitry. Its quiescent supply current is 1 mA per channel (2 mA total) under normal operation, with no low-power standby mode. For shutdown capability, consider TLV2773IDR (dual with shutdown) or TLV2775IDR (quad with shutdown).
Can TLV2772IDR drive a 600-Ω load with low distortion?
Yes, TLV2772IDR is specifically characterized for 600-Ω loading: at 1 kHz, it achieves 0.005% THD+N into 600 Ω with AV = 1, and maintains 0.016% at AV = 10. This performance is validated in the datasheet's Operating Characteristics table (page 9) and confirms suitability for telecom line drivers, audio interfaces, and other applications demanding high linearity into standard impedance loads.
