Product details
Overview
TLV2772QPWRG4Q1 from Texas Instruments is an automotive-qualified dual 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 specified across −40°C to 125°C for engine control and battery monitoring circuits.
For engineers reviewing the TLV2772QPWRG4Q1 datasheet, TLV2772QPWRG4Q1 pinout, TLV2772QPWRG4Q1 application, or TLV2772QPWRG4Q1 equivalent, key selection criteria include AEC-Q100 qualification, 2-channel rail-to-rail output drive into 600 Ω with 0.005% THD+N, low 17 nV/√Hz input noise, and TSSOP-8 package compatibility with space-constrained automotive PCB layouts.
Technical Context
The TLV2772QPWRG4Q1 implements a high-slew-rate CMOS input stage with rail-to-rail output swing enabled by complementary push-pull output transistors. Its 5.1 MHz bandwidth and 10.5 V/µs slew rate support fast settling (1.97 µs to 0.01%) in closed-loop configurations driving capacitive loads up to 100 pF.
It features independent shutdown control per channel, characterized input bias current of 2 pA (max), and common-mode input range extending to GND. The device maintains 60 dB CMRR and 70 dB SVR across its full operating temperature range, enabling stable performance in noisy automotive power domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct connection to 3.3 V or 5 V automotive rails without regulation |
| Slew Rate | 10.5 V/µs typ at VDD = 5 V - enables accurate reproduction of fast analog signals in sensor front-ends |
| Gain-Bandwidth Product | 5.1 MHz typ - allows stable unity-gain buffer or ≥10× closed-loop gain up to ~500 kHz |
| Input Offset Voltage | 0.36 mV max at 25°C, VDD = 5 V - ensures ≤1.8 mV error in 5 V full-scale precision measurement paths |
| Shutdown Current | < 1 µA per channel - reduces system standby power in battery-backed modules |
| Input Noise Voltage | 17 nV/√Hz at 10 kHz - preserves signal integrity in low-level sensor amplification stages |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets telecom-grade line driver requirements |
Pinout & Package
TSSOP-8 package (PW), 3.0 mm × 4.4 mm, 0.65 mm pitch, exposed thermal pad (not electrically connected).

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2772QPWRQ1 | No G4 suffix; identical electrical specs but lacks TI's enhanced green packaging (lead-free, RoHS-compliant finish) | Same AEC-Q100 qualification and TSSOP-8 footprint - suitable where RoHS compliance is not mandated | Select TLV2772QPWRQ1 only if legacy board designs require exact historical revision matching |
| LM7332QMA/NOPB | Higher 25 V/µs slew rate, 24 MHz GBW, ±15 V supply capable; no shutdown function; SOIC-8 only | Targeted at higher-voltage industrial motor control, not automotive 3.3/5 V domains | Choose LM7332QMA/NOPB only when >10 V/µs slew and dual-supply operation are mandatory |
Compared with TLV2772QPWRQ1, TLV2772QPWRG4Q1 adds RoHS-compliant surface finish and tighter process controls for automotive green manufacturing; compared with LM7332QMA/NOPB, it trades bandwidth and voltage range for lower quiescent current, smaller TSSOP-8 footprint, and integrated shutdown-making it optimal for space- and power-constrained automotive ECUs.

FAQ
What is the maximum operating temperature for TLV2772QPWRG4Q1?
The TLV2772QPWRG4Q1 is qualified for continuous operation from −40°C to +125°C ambient temperature per AEC-Q100 Grade 1 requirements. Electrical parameters including input offset voltage, CMRR, and supply current are fully characterized across this range, making TLV2772QPWRG4Q1 suitable for under-hood engine control applications where junction temperatures may exceed 125°C with proper thermal design.
Does TLV2772QPWRG4Q1 support true rail-to-rail input?
No, TLV2772QPWRG4Q1 features rail-to-rail *output* only. Its common-mode input voltage range extends to GND but does not reach VDD - it is specified as 0 V to (VDD − 1.3 V) at 25°C. This allows direct interfacing with ground-referenced sensors while maintaining dc precision, but requires level-shifting for signals near VDD. TLV2772QPWRG4Q1's input stage is optimized for low bias current (2 pA) rather than full rail-to-rail input swing.
How does the shutdown function operate on TLV2772QPWRG4Q1?
The SHDN pin (Pin 5) is active-low: pulling it below 0.8 V disables both amplifiers and reduces total supply current to <1 µA. During shutdown, outputs enter high-impedance state - they do not clamp or short. TLV2772QPWRG4Q1 achieves full turn-on within 1.5 µs after SHDN rises above 2.0 V, enabling rapid wake-up in duty-cycled automotive subsystems like tire pressure monitors.
Is TLV2772QPWRG4Q1 pin-compatible with standard TLV2772 variants?
Yes, TLV2772QPWRG4Q1 uses the same TSSOP-8 (PW) package and identical pinout as TLV2772QPWRQ1 and TLV2772IDR. All share the 1-OUTA, 2-IN−A, 3-IN+A, 4-GND, 5-SHDN, 6-VDD, 7-IN−B, 8-IN+B configuration. The G4 suffix denotes TI's enhanced green packaging (lead-free, halogen-free) but does not affect pin assignment, electrical behavior, or PCB layout - TLV2772QPWRG4Q1 is a drop-in replacement for legacy TLV2772QPWRQ1 in new designs.
What load capacitance can TLV2772QPWRG4Q1 safely drive without instability?
TLV2772QPWRG4Q1 is stable driving up to 100 pF capacitive load with 600 Ω series resistance, as verified by phase margin (46°) and gain margin (12 dB) measurements in the datasheet. For loads exceeding 100 pF, a 10 Ω to 22 Ω isolation resistor should be placed in series with the output to maintain stability. This capability makes TLV2772QPWRG4Q1 suitable for driving ADC input capacitors and long PCB traces in automotive domain controllers.
