Product details
Overview
TLV2772AQDRG4Q1 from Texas Instruments is a dual-channel, automotive-qualified CMOS operational amplifier with rail-to-rail output, 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, and micropower shutdown mode (IDD < 1 µA). It operates from 2.5 V to 5.5 V, delivers 360 µV max input offset voltage, and is characterized across −40°C to 125°C for engine control and ADAS sensor signal conditioning.
For engineers reviewing the TLV2772AQDRG4Q1 datasheet, TLV2772AQDRG4Q1 pinout, TLV2772AQDRG4Q1 application, or TLV2772AQDRG4Q1 equivalent, this page provides verified electrical specs, SOIC-8 package layout, automotive-grade thermal performance, and validated alternatives for precision analog front-end design in safety-critical systems.
Technical Context
The TLV2772AQDRG4Q1 implements a high-slew-rate CMOS input stage with rail-to-rail output swing, enabling full-scale signal fidelity into ADC reference or analog input stages. Its 17 nV/√Hz input noise voltage and 2 pA input bias current support low-noise, high-impedance sensing in medical and industrial measurement circuits.
It features integrated shutdown control (SHDN pin), allowing dynamic power management in battery-powered automotive subsystems. The device maintains stable phase margin (46°) and low THD+N (0.005% at 1 kHz, 600 Ω load), making it suitable for telecom line drivers and audio preamplifiers requiring clean signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typical at VDD = 5 V - enables fast settling for pulse-amplified sensor signals without distortion |
| Gain-Bandwidth Product | 5.1 MHz typical - supports closed-loop gains up to ~10 at 500 kHz while maintaining stability |
| Input Offset Voltage | 1.6 mV max at 25°C (TLV2772A-Q1 variant) - reduces DC error in precision instrumentation amplifiers |
| Supply Current per Channel | 1 mA typical at VDD = 2.7 V - allows dual op-amp operation within 2 mA total budget for low-power ECUs |
| Rail-to-Rail Output | Swings within 100 mV of VDD and GND at IOL/IOH = 2.2 mA - maximizes dynamic range when driving SAR ADC inputs |
| Shutdown Current | < 1 µA - cuts quiescent draw during sleep modes in always-on vehicle networks |
| Operating Temperature | −40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood and transmission control applications |
Pinout & Package
TLV2772AQDRG4Q1 is housed in an 8-pin SOIC (D) package with standard 1.27 mm pitch, 3.91 mm × 4.90 mm body size, and exposed pad not present. Pin numbering follows JEDEC MS-012AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output; drives loads up to ±50 mA with rail-to-rail swing |
| 2 | IN− A | Inverting input; high-impedance CMOS node (10¹² Ω) for precision feedback networks |
| 3 | IN+ A | Non-inverting input; common-mode range extends to GND − 0.3 V and VDD + 1.3 V |
| 4 | GND | Analog ground reference; must be low-impedance path to minimize PSRR degradation |
| 5 | SHDN | Active-low shutdown control; pulls IDD below 1 µA when driven ≤ 0.8 V |
| 6 | VDD | Positive supply rail; accepts 2.5–5.5 V; decoupling capacitor required at pin |
| 7 | IN− B | Inverting input for second channel; electrically isolated from Channel A |
| 8 | IN+ B | Non-inverting input for second channel; shares same VDD/GND rails as Channel A |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 certified - meets reliability and stress-test requirements for production automotive electronics |

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 |
|---|---|---|---|
| TLV2772QDRQ1 | Higher max input offset voltage (2.7 mV vs. 1.9 mV) and no A-grade trimming; otherwise identical pinout, specs, and qualification. | Acceptable for cost-sensitive ECU modules where 0.3% additional DC error is tolerable. | Select TLV2772QDRQ1 when absolute minimum offset isn't required and BOM cost reduction is prioritized. |
| OPA2333AIDRGT | Zero-drift architecture; 0.02 µV/°C offset drift vs. 2 µV/°C; higher supply current (17 µA/ch); no shutdown pin. | Better long-term DC stability in temperature-varying environments but lacks power-gating capability. | Choose OPA2333AIDRGT only when ultra-low drift dominates over shutdown functionality and quiescent power. |
Compared with TLV2772AQDRG4Q1, TLV2772QDRQ1 trades tighter offset for lower cost without altering layout or firmware, while OPA2333AIDRGT eliminates drift-induced calibration but increases system power and removes dynamic power control-making TLV2772AQDRG4Q1 optimal for balanced performance in automotive signal chains.

FAQ
What is the maximum supply voltage for TLV2772AQDRG4Q1?
The absolute maximum supply voltage for TLV2772AQDRG4Q1 is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation above 5.5 V risks permanent damage and violates AEC-Q100 stress limits. At 5 V, TLV2772AQDRG4Q1 achieves its full 10.5 V/µs slew rate and 5.1 MHz gain-bandwidth product while maintaining rail-to-rail output swing.
Does TLV2772AQDRG4Q1 support true rail-to-rail input?
No, TLV2772AQDRG4Q1 features rail-to-rail *output* only. Its input common-mode voltage range extends from GND − 0.3 V to VDD + 1.3 V (at VDD = 5 V), meaning it accepts inputs slightly beyond the supply rails but does not operate with inputs at the full VDD or GND extremes. This is sufficient for most sensor interface applications where signals are biased within the supply range.
How does the shutdown function work on TLV2772AQDRG4Q1?
The SHDN pin (Pin 5) is active-low: driving it ≤ 0.8 V places both amplifiers into micropower shutdown, reducing total supply current to < 1 µA. Pulling SHDN ≥ 2.0 V (at VDD = 5 V) enables normal operation. No external pull-up is required, but a 10 kΩ pull-up to VDD ensures robust default-enable behavior during power-up sequencing in automotive microcontrollers.
Is TLV2772AQDRG4Q1 pin-compatible with TLV2772QDRQ1?
Yes, TLV2772AQDRG4Q1 and TLV2772QDRQ1 share identical SOIC-8 (D) package dimensions, pinout, and footprint. Both devices use the same pin assignments for OUT A, IN− A, IN+ A, GND, SHDN, VDD, IN− B, and IN+ B - enabling drop-in replacement without PCB modifications when upgrading from standard to A-grade offset performance.
What is the typical input bias current of TLV2772AQDRG4Q1 at 125°C?
The typical input bias current of TLV2772AQDRG4Q1 is 2 pA at 25°C and rises to ≤ 350 pA across the full −40°C to +125°C operating range. This remains exceptionally low compared to bipolar-input op-amps, preserving high-impedance sensor node accuracy even at elevated temperatures encountered near powertrain components.
