Product details
Overview
TLV2772QPWRG4 from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for automotive applications. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, and operates from 2.5 V to 5.5 V single supply - enabling high-fidelity signal conditioning in ADC driver and sensor front-end circuits within engine control units and ADAS modules.
For engineers reviewing the TLV2772QPWRG4 datasheet, TLV2772QPWRG4 pinout, TLV2772QPWRG4 application, or TLV2772QPWRG4 equivalent, key selection criteria include its Q-temp automotive qualification (−40°C to 125°C), micropower shutdown mode (<1 µA per channel), low THD+N (0.005% into 600 Ω), and MSOP-8 package compatibility with space-constrained automotive PCB layouts.
Technical Context
The TLV2772QPWRG4 employs a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, supporting precision DC-coupled measurement paths. Its rail-to-rail output stage drives loads up to ±50 mA while maintaining linearity across the full supply range.
Designed for single-supply operation, it features internal compensation for unity-gain stability with 100 pF capacitive load, and includes independent shutdown control per channel - critical for power sequencing in automotive domain controllers where dynamic channel enablement reduces system-level quiescent current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typ - enables accurate reproduction of fast transient signals in motor position feedback loops. |
| Gain-Bandwidth Product | 5.1 MHz typ - supports closed-loop gains up to 10 at 500 kHz without phase margin degradation. |
| Input Offset Voltage | 360 µV max at 25°C - ensures <±1 LSB error when driving 12-bit SAR ADCs with 3.3 V reference. |
| Supply Current (per channel) | 1 mA typ at 2.7 V - allows dual op-amp operation within 2 mA total budget for battery-backed subsystems. |
| Shutdown Current | <1 µA per channel - reduces standby power in infotainment audio amplifiers during sleep mode. |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets telecom-grade analog signal integrity requirements in telematics modems. |
| Operating Temperature | −40°C to +125°C - qualified per AEC-Q100 Grade 2 for under-hood engine management applications. |
Pinout & Package
TLV2772QPWRG4 is housed in an 8-pin MSOP (PW) package with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm. The package supports automated optical inspection and provides enhanced thermal dissipation over SOT-23 alternatives.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Inverting amplifier output - directly interfaces with ADC input or transimpedance feedback node. |
| 2 | IN−A | Inverting input - connects to feedback network or current-sense resistor in precision current monitoring. |
| 3 | IN+A | Non-inverting input - accepts sensor bridge output or reference voltage with minimal loading (2 pA bias). |
| 4 | GND | Analog ground reference - must be star-connected to minimize ground bounce in mixed-signal domains. |
| 5 | VDD | Positive supply - accepts 2.5–5.5 V; decoupling capacitor required within 5 mm for EMI suppression. |
| 6 | IN+B | Non-inverting input (Channel B) - isolated from Channel A for differential sensor pair processing. |
| 7 | IN−B | Inverting input (Channel B) - enables matched gain configuration with Channel A for common-mode rejection. |
| 8 | OUTB | Output (Channel B) - independently routable for dual-path signal conditioning without crosstalk. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 100 mV of VDD/GND at 2.2 mA load - eliminates level-shifting ICs in 3.3 V systems interfacing with ADCs. |
| Micropower shutdown mode | Reduces IDD to <1 µA per channel - enables firmware-controlled channel disable in always-on vehicle networks. |
| Low distortion into 600 Ω | 0.005% THD+N at 1 kHz - preserves signal fidelity in analog voice/data channels for rear-seat entertainment systems. |
| High CMRR (84 dB min) | Rejects engine harness noise coupled onto differential sensor lines - critical for crankshaft position sensing. |
| Q-temp automotive qualification | Tested per AEC-Q100 with extended temperature cycling and HTOL - ensures reliability in powertrain ECUs. |

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 |
|---|---|---|---|
| TLV2772IDR | Same silicon, industrial temp range (−40°C to 125°C) but non-automotive qualified; no AEC-Q100 testing. | Lacks Q-temp documentation and traceability - unsuitable for safety-critical powertrain functions. | Select only for non-automotive industrial controls where cost sensitivity outweighs qualification requirements. |
| LM7332MA/NOPB | Higher supply current (2.3 mA/ch), wider VDD range (2.7–36 V), no shutdown mode, higher VIO (1.8 mV). | Supports high-voltage battery monitoring but lacks micropower shutdown and automotive qualification. | Prefer for 12/24 V automotive subsystems requiring wide supply tolerance, not for low-power sensor nodes. |
Compared with TLV2772QPWRG4, TLV2772IDR omits automotive qualification and traceability while retaining identical electrical specs, whereas LM7332MA/NOPB trades micropower operation and low offset for high-voltage robustness - making TLV2772QPWRG4 the sole choice for AEC-Q100-compliant, low-quiescent dual op-amp needs.

FAQ
What is the operating temperature range for TLV2772QPWRG4?
The TLV2772QPWRG4 is qualified for operation from −40°C to +125°C and meets AEC-Q100 Grade 2 requirements. This range is validated through extended temperature cycling, high-temperature operating life (HTOL), and thermal shock testing - ensuring reliability in under-hood automotive environments where ambient temperatures exceed 105°C.
Does TLV2772QPWRG4 support rail-to-rail input as well as output?
No, TLV2772QPWRG4 features rail-to-rail output only. Its common-mode input voltage range extends from GND to VDD − 1.3 V at 2.7 V supply, meaning it cannot accept signals within 1.3 V of VDD. This limitation is explicitly defined in the recommended operating conditions table and must be accounted for in sensor interface design.
How does the shutdown function operate on TLV2772QPWRG4?
The TLV2772QPWRG4 does not include dedicated shutdown pins. Shutdown functionality is implemented via external circuitry controlling VDD - when VDD is pulled below 1.5 V, supply current drops to <1 µA per channel. This differs from TLV2773/TLV2775 variants which feature active-low SHDN pins.
What is the maximum capacitive load TLV2772QPWRG4 can drive stably?
TLV2772QPWRG4 is unity-gain stable with up to 100 pF capacitive load, as verified in the operating characteristics section. Driving larger loads requires isolation resistors (≥10 Ω) in series with the output to maintain phase margin above 46° and prevent oscillation in ADC driver configurations.
Is TLV2772QPWRG4 pin-compatible with other TLV277x variants in MSOP-8?
Yes, TLV2772QPWRG4 shares identical pinout with TLV2772CDGK, TLV2772IDGK, and TLV2772AIDGK in the MSOP-8 (PW/DGK) package. Pin assignments for OUTA, IN−A, IN+A, GND, VDD, IN+B, IN−B, and OUTB are consistent across all TLV2772 variants in this footprint.
