Product details
Overview
TLV2772QDRG4Q1 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 TLV2772QDRG4Q1 datasheet, TLV2772QDRG4Q1 pinout, TLV2772QDRG4Q1 application, or TLV2772QDRG4Q1 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 analog front-ends.
Technical Context
The TLV2772QDRG4Q1 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 achieves 46° phase margin with 600 Ω load and 100 pF capacitance, supporting robust driving of ADC reference inputs without external compensation.
It integrates independent shutdown control per channel via dedicated SHDN pins, reducing total supply current to <1 µA in sleep mode while maintaining fast wake-up response. The device's rail-to-rail output swing (within 100 mV of rails at 2.2 mA) and wide common-mode input range (to within 0.3 V of VDD) support single-supply operation in space-constrained automotive modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel automotive op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2772AQDRQ1 | Lower 1.6 mV max input offset voltage (vs. 2.5 mV for TLV2772QDRG4Q1) at 25°C; same package, pinout, and temperature range | Better suited for ultra-precision current sensing where sub-mV offset is critical | Select TLV2772AQDRQ1 when VIO budget is ≤1.6 mV; otherwise TLV2772QDRG4Q1 offers cost advantage |
| LM7332QMA/NOPB | Higher 20 V/µs slew rate but 2.2 mA/channel supply current; SOIC-8, AEC-Q100 Grade 1, 2.7–36 V supply | Required for higher-voltage battery monitoring (e.g., 12 V/24 V systems) with faster transient response | Choose LM7332QMA/NOPB only when supply exceeds 5.5 V or slew rate >10.5 V/µs is mandatory |
Compared with TLV2772AQDRQ1, TLV2772QDRG4Q1 trades 0.9 mV higher VIO for lower cost in volume production; versus LM7332QMA/NOPB, it reduces quiescent current by 55% at 5 V but lacks high-voltage tolerance - making it optimal for 3.3 V/5 V automotive subsystems prioritizing power efficiency.

FAQ
What is the maximum operating supply voltage for TLV2772QDRG4Q1?
The absolute maximum supply voltage for TLV2772QDRG4Q1 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 exceeding safe power dissipation limits and may compromise AEC-Q100 reliability margins. TLV2772QDRG4Q1 must be used within 2.5–5.5 V for guaranteed performance across −40°C to 125°C.
Does TLV2772QDRG4Q1 support true rail-to-rail input?
No, TLV2772QDRG4Q1 features rail-to-rail *output* only. Its common-mode input voltage range extends from GND to VDD − 0.3 V, meaning the inputs cannot accept signals within 0.3 V of VDD. This limitation is documented in the electrical characteristics table for VICR. TLV2772QDRG4Q1 remains suitable for most single-supply sensor interfaces where the signal stays below VDD − 0.3 V.
How does the shutdown function operate on TLV2772QDRG4Q1?
TLV2772QDRG4Q1 does not integrate a shutdown pin - the part number TLV2772QDRG4Q1 corresponds to the standard TLV2772-Q1 variant without shutdown capability. Shutdown functionality is available only on TLV2770-Q1, TLV2773-Q1, and TLV2775-Q1 variants. TLV2772QDRG4Q1 draws 1 mA per channel continuously and requires external power gating for low-current states.
What is the thermal resistance θJA for TLV2772QDRG4Q1 in SOIC-8 package?
The junction-to-ambient thermal resistance (θJA) for TLV2772QDRG4Q1 in the SOIC-8 (D) package is 120°C/W, as specified in the Dissipation Rating Table of the datasheet. This value assumes standard JEDEC 2-layer board conditions. With 2 mA total supply current at 5.5 V, power dissipation is ~11 mW, resulting in <1.4°C junction-to-ambient rise - well within safe limits for operation up to 125°C ambient.
Is TLV2772QDRG4Q1 pin-compatible with other TLV277x-Q1 family members?
TLV2772QDRG4Q1 is pin-compatible with TLV2772AQDRQ1 and TLV2772QPWRQ1 (TSSOP-8), sharing identical SOIC-8 pinout and function mapping. However, it is *not* pin-compatible with TLV2770-Q1, TLV2771-Q1, TLV2773-Q1, or TLV2774-Q1 due to differing channel counts, shutdown pin presence, and pin assignments. Always verify pinout diagrams before PCB layout reuse.
