Product details
Overview
TLV2772AQPWRG4Q1 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 TLV2772AQPWRG4Q1 datasheet, TLV2772AQPWRG4Q1 pinout, TLV2772AQPWRG4Q1 application, or TLV2772AQPWRG4Q1 equivalent, key selection criteria include its high-speed rail-to-rail output drive into 600 Ω loads (0.005% THD+N), low 17 nV/√Hz input noise, and AEC-Q100 Grade 1 qualification for under-hood automotive use.
Technical Context
The TLV2772AQPWRG4Q1 implements a CMOS input stage with 2-pA typical input bias current and 10¹² Ω differential input resistance, enabling high-impedance sensor interfacing. Its unity-gain stable architecture supports fast settling (1.97 µs to 0.01%) and maintains 46° phase margin with 600 Ω load and 100 pF capacitance.
It integrates independent shutdown control per channel, reducing total supply current to <1 µA in disabled state while preserving rail-to-rail output swing (within 100 mV of rails at 2.2 mA) and maintaining CMRR >84 dB across temperature. The device is optimized for single-supply operation with common-mode input range extending to GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - Enables direct interface with 3.3 V and 5 V microcontrollers without level-shifting. |
| Slew Rate | 10.5 V/µs (typ at 5 V) - Supports clean amplification of fast analog signals up to ~1 MHz without slew-induced distortion. |
| Gain-Bandwidth Product | 5.1 MHz (typ at 5 V) - Allows stable closed-loop gain ≥10 at 500 kHz for precision active filter or ADC driver designs. |
| Input Offset Voltage | 1.6 mV (max at 25°C, TLV2772A-Q1 variant) - Ensures ≤1.6 mV DC error in 12-bit systems with 2.5 V full-scale reference. |
| Shutdown Current | <1 µA per channel - Reduces system standby power by >99.9% versus active mode (1 mA/channel), critical for battery-powered modules. |
| Output Drive | Rail-to-rail swing, ±2.2 mA - Drives ADC reference inputs or 600 Ω telecom loads with minimal headroom loss and 0.005% THD+N. |
| Input Noise Voltage | 17 nV/√Hz (at 10 kHz, 5 V) - Limits integrated noise to ~1.7 µV RMS in 100 kHz bandwidth, suitable for precision sensor front-ends. |
Pinout & Package
TSSOP-8 (PW) package: 3.0 mm × 4.4 mm, 0.65 mm pitch, thermally enhanced with exposed pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ±2.2 mA into 600 Ω load. |
| 2 (IN− A) | Channel A inverting input | High-impedance CMOS node (10¹² Ω); requires matched trace impedance for optimal CMRR. |
| 3 (IN+ A) | Channel A non-inverting input | Accepts common-mode input down to GND; enables single-supply sensor biasing without negative rail. |
| 4 (GND) | Analog ground reference | Must be star-connected to minimize noise coupling between channels and digital sections. |
| 5 (SHDN) | Active-low shutdown control | Pulling low disables both amplifiers; high-impedance when open; compatible with 1.8 V logic. |
| 6 (VDD) | Positive supply | Decoupling capacitor (0.1 µF ceramic) required within 5 mm to suppress supply noise above 100 kHz. |
| 7 (OUT B) | Channel B output | Independent output; identical specs to OUT A; supports dual-sensor or differential pair configurations. |
| 8 (IN− B) | Channel B inverting input | Electrically isolated from IN− A; allows separate feedback networks for each channel. |

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 |
|---|---|---|---|
| TLV2772QPWRQ1 | Higher 2.7 mV max input offset voltage (vs. 1.6 mV for TLV2772AQPWRG4Q1) at 25°C; otherwise identical specs and pinout. | Less suited for high-accuracy current sensing or precision thermistor interfaces requiring sub-2 mV VIO. | Select TLV2772QPWRQ1 only if cost sensitivity outweighs need for lowest VIO in production calibration-limited designs. |
| LM7332QMA/NOPB | Higher 20 V/µs slew rate and 22 MHz GBW, but 2.5 mA/channel supply current and no shutdown function. | Better for ultra-high-speed signal chains (e.g., active filters >1 MHz), but unsuitable for low-power or battery-backed modules. | Choose LM7332QMA/NOPB when speed dominates power budget; avoid where shutdown or sub-1 mA operation is mandatory. |
Compared with TLV2772QPWRQ1, TLV2772AQPWRG4Q1 offers tighter input offset for improved DC accuracy; compared with LM7332QMA/NOPB, it trades raw bandwidth for 75% lower active current and integrated shutdown-critical for automotive subsystems with strict ISO 16750-2 power budgets.

FAQ
What is the maximum operating temperature range for TLV2772AQPWRG4Q1?
The TLV2772AQPWRG4Q1 is qualified for continuous operation from −40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This range is validated across all electrical parameters including input offset voltage, CMRR, and supply current, making it suitable for engine control and transmission control unit applications.
Does TLV2772AQPWRG4Q1 support true rail-to-rail input?
No, TLV2772AQPWRG4Q1 features rail-to-rail *output* only. Its common-mode input voltage range extends to GND but does not reach VDD; at 5 V supply, VICR is specified from 0 V to 3.8 V. For rail-to-rail input capability, consider TI's TLV9062-Q1 or similar families.
How does the shutdown function operate on TLV2772AQPWRG4Q1?
The SHDN pin (Pin 5) is active-low: pulling it below 0.8 V disables both amplifiers, reducing total supply current to <1 µA. When left open or pulled high (>2.0 V), the device operates normally. No external pull-up is required-the internal weak pull-up ensures default active operation if unconnected.
What is the typical THD+N performance of TLV2772AQPWRG4Q1 when driving a 600-Ω load?
At 1 kHz, 5 V supply, and AV = 1, TLV2772AQPWRG4Q1 achieves 0.005% THD+N into a 600-Ω load-matching telecom line-driver specifications. This value is confirmed in the official datasheet (SGLS179D, page 8, Table "Operating Characteristics at VDD = 5 V") and remains stable across temperature.
Is TLV2772AQPWRG4Q1 pin-compatible with other devices in the TLV277x-Q1 family?
Yes-TLV2772AQPWRG4Q1 shares identical TSSOP-8 (PW) pinout with TLV2772QPWRQ1, TLV2772QDRQ1, and TLV2772AQDRQ1. All variants use the same pin mapping: OUT A, IN− A, IN+ A, GND, SHDN, VDD, OUT B, IN− B. This enables drop-in replacement for VIO-critical upgrades without PCB changes.
