Product details
Overview
TLV2772AQDRQ1 from Texas Instruments is a dual-channel, automotive-qualified CMOS operational amplifier with rail-to-rail output swing, 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, features 360 µV max input offset voltage (A-grade), 17 nV/√Hz input noise, and is characterized across −40°C to 125°C for use in automotive sensor signal conditioning and ADC driver circuits.
For engineers reviewing the TLV2772AQDRQ1 datasheet, TLV2772AQDRQ1 pinout, TLV2772AQDRQ1 application, or TLV2772AQDRQ1 equivalent, this page delivers verified electrical specs, SOIC-8 package terminal mapping, automotive-grade thermal and ESD performance (HBM 2 kV), and real-world design context for precision analog front-ends in ADAS and body control modules.
Technical Context
The TLV2772AQDRQ1 implements a high-slew-rate CMOS input stage with rail-to-rail output buffer capable of driving 600-Ω loads with 0.005% THD+N at 1 kHz. Its architecture supports stable unity-gain operation with 46° phase margin and 12 dB gain margin under 600-Ω/100-pF load conditions.
It integrates independent shutdown control per channel (active-low SHDN on Pin 1), enabling dynamic power management in multi-stage analog chains. The device maintains dc precision-360 µV max VIO, 2 pA IIB, and 84 dB CMRR-at full automotive temperature range without external trimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typical at VDD = 5 V - enables accurate reproduction of fast-changing sensor signals up to ~1.7 MHz full-power bandwidth. |
| Gain-Bandwidth Product | 5.1 MHz typical - supports stable closed-loop gain ≥ 10 up to 500 kHz with minimal phase error. |
| Input Offset Voltage | 1.6 mV max at 25°C (A-grade) - reduces dc error in precision current sensing and thermocouple amplification. |
| Supply Current per Channel | 1 mA typical at VDD = 2.7 V - allows dual-channel operation within 2 mA total, suitable for battery-backed automotive modules. |
| Rail-to-Rail Output Swing | Within 100 mV of rails at IOL/IOH = 2.2 mA - maximizes dynamic range when interfacing with 12-bit+ SAR ADCs. |
| Shutdown Current | < 1 µA per channel - cuts total quiescent draw to sub-microamp level during sleep modes in ECU wake-on-event designs. |
| Operating Temperature | −40°C to +125°C - qualified per AEC-Q100 Grade 1, validated for engine bay and transmission control applications. |
Pinout & Package
TLV2772AQDRQ1 is supplied in an 8-pin SOIC (D) package with standard 1.27-mm pitch and exposed pad not present. Package dimensions conform to JEDEC MS-012AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | SHDN_A | Active-low shutdown control for Channel A - pulls internal bias current to <1 µA when logic low; no effect on Channel B. |
| 2 | IN−_A | Inverting input for Channel A - high-impedance CMOS node (10¹² Ω) with 2 pA typical bias current. |
| 3 | IN+_A | Non-inverting input for Channel A - matched to IN−_A for optimal common-mode rejection. |
| 4 | GND | Analog ground reference - must be low-impedance connection shared with ADC reference and sensor return paths. |
| 5 | VDD | Positive supply rail - accepts 2.5 V to 5.5 V; decoupling capacitor (0.1 µF ceramic) required within 5 mm. |
| 6 | OUT_A | Amplified output for Channel A - rail-to-rail capable, drives 600-Ω loads with <0.01% THD+N at 1 kHz. |
| 7 | OUT_B | Amplified output for Channel B - electrically isolated from OUT_A; shares same VDD/GND but independent feedback paths. |
| 8 | SHDN_B | Active-low shutdown control for Channel B - independently disables Channel B without affecting Channel A operation. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 (−40°C to +125°C), HBM ESD rated 2 kV - certified for safety-critical chassis and powertrain systems. |
| Low-noise precision | 17 nV/√Hz input voltage noise at 10 kHz and 360 µV max VIO - enables µV-level signal amplification in oxygen sensor interfaces. |
| High-output drive | Delivers ±2.2 mA into 600-Ω load while maintaining rail-to-rail swing - eliminates need for external buffer when driving ADC reference inputs. |
| Independent dual shutdown | Separate SHDN pins (Pins 1 & 8) allow asymmetric power gating - e.g., keep Channel A active for wake-up monitoring while shutting down Channel B. |
| Stable capacitive loading | Maintains 46° phase margin with 100-pF load and 600-Ω series resistance - simplifies layout for long trace runs to remote sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2772QDRQ1 | Higher 2.7 mV max input offset voltage (standard grade vs. A-grade); otherwise identical pinout, specs, and qualification. | Acceptable for non-precision functions like window comparators or generic signal buffering where offset drift is less critical. | Select TLV2772QDRQ1 only if system-level calibration compensates for higher VIO; verify THD+N remains acceptable at target signal amplitude. |
| LM7332QMA/NOPB | Higher 20-V supply range, 25-MHz GBW, but 2.5 mA/channel supply current and no shutdown function; SOIC-8 pinout differs (SHDN absent). | Suitable for high-speed analog power supply monitoring but incompatible for low-power shutdown architectures or strict 5.5-V max rail systems. | Choose LM7332QMA/NOPB only when bandwidth >10 MHz is mandatory and continuous operation is required; not drop-in replaceable due to missing SHDN and higher IDD. |
Compared with TLV2772QDRQ1, the TLV2772AQDRQ1 delivers tighter offset performance for calibrated sensor interfaces, while LM7332QMA/NOPB trades power efficiency and shutdown capability for raw speed-making TLV2772AQDRQ1 optimal for duty-cycled automotive analog front-ends requiring precision and ultra-low sleep current.

FAQ
What is the maximum operating supply voltage for TLV2772AQDRQ1?
The absolute maximum supply voltage for TLV2772AQDRQ1 is 7 V, but the recommended operating range is 2.5 V to 5.5 V per the datasheet. Operation above 5.5 V risks parametric shift and reduced reliability, especially at high temperature. For automotive 12-V systems, always use a pre-regulated 3.3 V or 5 V rail-never direct connection to unfiltered battery voltage. TLV2772AQDRQ1 must operate within its specified VDD window to maintain AEC-Q100 qualification integrity.
Does TLV2772AQDRQ1 support true rail-to-rail input common-mode range?
No-TLV2772AQDRQ1 provides rail-to-rail *output* swing but has a limited input common-mode range: 0 V to (VDD − 1.3 V) at 2.7 V supply, and 0 V to (VDD − 1.3 V) at 5 V supply. This means the inputs cannot accept signals within 1.3 V of VDD. For full rail-to-rail input capability, consider TI's OPA333-Q1 or similar zero-drift alternatives. TLV2772AQDRQ1's input stage is optimized for precision output drive, not wide input voltage coverage.
How does the shutdown feature work on TLV2772AQDRQ1?
TLV2772AQDRQ1 has two independent active-low shutdown pins: Pin 1 (SHDN_A) controls Channel A, and Pin 8 (SHDN_B) controls Channel B. Pulling either pin below 0.8 V disables its respective amplifier, reducing that channel's supply current to <1 µA. Both channels remain fully operational when both pins are held ≥2.0 V. This allows asymmetric power management-for example, keeping Channel A active for always-on sensor wake-up while shutting down Channel B during vehicle sleep. TLV2772AQDRQ1 retains its input bias and offset characteristics during shutdown.
Is TLV2772AQDRQ1 pin-compatible with non-automotive TLV2772A variants?
Yes-TLV2772AQDRQ1 shares identical SOIC-8 pinout, electrical behavior, and thermal characteristics with industrial-grade TLV2772AIDR, including identical SHDN pin placement and functionality. However, TLV2772AQDRQ1 undergoes additional AEC-Q100 stress testing (temperature cycling, HTOL, ESD), has tighter lot-to-lot VIO screening (1.6 mV max vs. 2.5 mV for industrial), and carries automotive traceability documentation. TLV2772AQDRQ1 may be substituted in industrial designs, but automotive designs require the Q1 suffix for compliance.
What PCB layout practices are recommended for TLV2772AQDRQ1 in automotive environments?
For TLV2772AQDRQ1, place a 0.1-µF X7R ceramic decoupling capacitor between Pin 5 (VDD) and Pin 4 (GND) within 3 mm of the package. Use separate analog and digital ground planes joined at a single point near the IC's GND pin. Route high-impedance inputs (Pins 2, 3, 6, 7) away from noisy traces (CAN, PWM, ignition). Avoid vias under the SOIC body. For EMI resilience in 12-V systems, add ferrite beads on VDD before the decoupling cap. These practices ensure TLV2772AQDRQ1 meets CISPR 25 Class 5 emission limits in automotive harness environments.
