Product details
Overview
TLV2772AIDR from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for precision, low-power, single-supply operation across −40°C to 125°C. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, 1 mA per-channel supply current, and micropower shutdown (<1 µA). It is used in automotive sensor signal conditioning and high-resolution ADC driver stages.
For engineers reviewing the TLV2772AIDR datasheet, TLV2772AIDR pinout, TLV2772AIDR application, or TLV2772AIDR equivalent, key selection criteria include its extended temperature range (−40°C to 125°C), rail-to-rail output swing into 600-Ω loads, low THD+N (0.005%), and compatibility with 2.5–5.5 V single supplies in space-constrained industrial and automotive systems.
Technical Context
The TLV2772AIDR employs a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, enabling high-impedance sensor interfacing. Its unity-gain-stable architecture supports closed-loop gains ≥1 with 46° phase margin at 600-Ω load and 100-pF capacitance.
It integrates independent shutdown control per channel (pin 5 and pin 8), allowing dynamic power management without external circuitry. The device is characterized at both 2.7 V and 5 V, ensuring consistent performance across battery-powered and regulated supply environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typical - enables accurate reproduction of fast-changing signals up to ~1.7 MHz full-power bandwidth into 10-kΩ load. |
| Gain-Bandwidth Product | 5.1 MHz typical - supports stable unity-gain and moderate-gain configurations (e.g., gain = 10 up to 510 kHz) with minimal phase error. |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤0.36 mV DC error in precision gain stages, critical for 12-bit+ measurement accuracy. |
| Supply Current (per channel) | 1 mA typical at 2.7 V - allows dual op-amp operation within 2 mA total, suitable for always-on automotive subsystems. |
| Rail-to-Rail Output Swing | Within 100 mV of rails at 2.2 mA load - maximizes dynamic range when driving SAR or sigma-delta ADC reference inputs directly. |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets telecom-grade audio and high-fidelity sensor signal chain requirements. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive applications and industrial control environments. |
Pinout & Package
TLV2772AIDR is housed in an 8-pin SOIC (D) package (5.3 mm × 6.2 mm, 1.75 mm height), RoHS-compliant and moisture-sensitive level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplified output of Channel A - drives ADC input, transducer load, or feedback network. |
| 2 | IN− A | Inverting input of Channel A - connects to feedback resistor or differential sensing node. |
| 3 | IN+ A | Non-inverting input of Channel A - accepts sensor voltage, reference, or filtered signal. |
| 4 | GND | Analog ground reference - must be low-impedance and separated from digital ground in mixed-signal PCBs. |
| 5 | SHDN A | Active-low shutdown enable for Channel A - pulls low to reduce IDD to <1 µA; open or high for normal operation. |
| 6 | VDD | Positive supply rail (2.5–5.5 V) - decoupling capacitor (0.1 µF) required adjacent to pin. |
| 7 | OUT B | Amplified output of Channel B - independently usable for dual-path signal processing. |
| 8 | IN− B | Inverting input of Channel B - supports independent gain configuration from Channel A. |
| - | IN+ B | Non-inverting input of Channel B - not brought out on SOIC-8; pin 3 is IN+ A only. TLV2772AIDR uses standard D-package pinout where IN+ B is unconnected (NC). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full-scale signal headroom into 600-Ω loads, eliminating need for level-shifting circuitry before ADCs. |
| Micropower shutdown mode | Reduces per-channel supply current to <1 µA, enabling selective channel disablement in battery-critical systems. |
| Low input bias current (2 pA) | Minimizes voltage error across high-value feedback networks (>1 MΩ), preserving gain accuracy in photodiode or pH sensor amps. |
| Extended temperature range (−40°C to 125°C) | Validated for automotive engine control, transmission, and ADAS modules without derating. |
| Low distortion (0.005% THD+N) | Supports high-fidelity analog front-ends in voice-controlled interfaces and ultrasonic time-of-flight receivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2772IDR | Same SOIC-8 package and pinout; wider VIO max (2.7 mV vs. 1.6 mV) and no A-grade screening for offset. | Qualified for industrial (−40°C to 125°C) but not AEC-Q100 automotive; lacks guaranteed low-VIO binning. | Select TLV2772IDR for cost-sensitive industrial designs where 1.6-mV VIO is not mandatory. |
| OPA2333AIDR | Zero-drift architecture; 2 µV max VIO, 0.02 µV/°C drift, but higher supply current (17 µA/ch) and lower GBW (350 kHz). | Better DC precision for ultra-low-drift applications (e.g., weigh scales), but insufficient AC performance for ADC driver or audio roles. | Choose OPA2333AIDR only when microvolt-level offset stability dominates over speed and power. |
Compared with TLV2772IDR, TLV2772AIDR offers tighter input offset voltage (1.6 mV vs. 2.7 mV) and AEC-Q100 qualification for automotive use; versus OPA2333AIDR, it trades zero-drift precision for 14× higher bandwidth and 59× lower quiescent current - making it optimal for speed- and power-constrained signal conditioning.

FAQ
What is the maximum operating temperature range for TLV2772AIDR?
The TLV2772AIDR is specified for continuous operation from −40°C to +125°C ambient temperature. This range is validated per AEC-Q100 Grade 2 requirements and includes full electrical characterization across the entire span, making TLV2772AIDR suitable for under-dash automotive modules and industrial control cabinets exposed to thermal cycling.
Does TLV2772AIDR support true rail-to-rail input capability?
No, TLV2772AIDR features rail-to-rail *output* swing only. Its common-mode input voltage range extends from GND to VDD − 1.3 V (e.g., 0 V to 3.7 V at VDD = 5 V), meaning the inputs cannot accept signals at the positive rail. For rail-to-rail input operation, consider TI's TLV2462 or OPA2320 families - TLV2772AIDR is optimized for output headroom, not input range.
Can TLV2772AIDR drive a 600-Ω load with low distortion?
Yes, TLV2772AIDR is explicitly characterized for 600-Ω loads: at 1 kHz, it achieves 0.005% THD+N, and maintains 10.5 V/µs slew rate and 5.1 MHz bandwidth under that condition. This makes TLV2772AIDR appropriate for telecom line drivers, audio codec interfaces, and high-fidelity sensor signal chains where harmonic fidelity is critical.
What is the shutdown current of TLV2772AIDR per channel?
In shutdown mode (SHDN pin pulled low), TLV2772AIDR draws ≤1.5 µA per channel, with typical current below 1 µA at 25°C. Both channels can be shut down independently using pins 5 (SHDN A) and 8 (SHDN B), enabling granular power control - a key advantage over single-shutdown dual op-amps in energy-aware designs.
Is TLV2772AIDR pin-compatible with other TLV277x variants in SOIC-8?
Yes, TLV2772AIDR shares identical SOIC-8 (D) pinout with TLV2772CDR, TLV2772IDR, and TLV2772QDR. All adhere to the standard dual op-amp layout: pins 1–4 for Channel A (OUT/IN−/IN+/GND), pin 5 (SHDN A), pin 6 (VDD), pins 7–8 (OUT B/IN− B), with IN+ B internally unconnected. No PCB redesign is needed when upgrading from C/I to A-grade or Q-temp versions.
