Product details
Overview
TLV2772QDRQ1 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 battery monitoring circuits.
For engineers reviewing the TLV2772QDRQ1 datasheet, TLV2772QDRQ1 pinout, TLV2772QDRQ1 application, or TLV2772QDRQ1 equivalent, key selection criteria include its high-speed rail-to-rail output drive into 600 Ω loads, low 17 nV/√Hz input noise, and AEC-Q100 Grade 1 qualification for under-hood signal conditioning.
Technical Context
The TLV2772QDRQ1 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 0.005% THD+N at 1 kHz driving 600 Ω, with phase margin of 46° and gain margin of 12 dB under capacitive load conditions.
It features independent shutdown control per channel in SOIC-8 packaging, supporting power-gating in multi-stage analog front-ends. The device maintains rail-to-rail output swing (within 100 mV of rails at 2.2 mA) and common-mode input range extending to GND, making it suitable for single-supply data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typ at VDD = 5 V - enables fast settling for 12-bit ADC driver applications with ≤ 1.97 µs to 0.01%. |
| Gain-Bandwidth Product | 5.1 MHz typ - supports stable closed-loop operation up to ~1 MHz with moderate gain (e.g., AV = 5). |
| Input Offset Voltage | 0.36 mV typ (max 1.6 mV for A-grade) at 25°C, VDD = 5 V - ensures ≤ 0.03% error in precision current-sense amplification. |
| Supply Current per Channel | 1 mA typ at VDD = 5 V - allows dual-channel operation within 2 mA total, ideal for low-power automotive modules. |
| Shutdown Current | < 1 µA - reduces system standby power by >99.9% when unused channels are disabled. |
| Input Noise Voltage | 17 nV/√Hz at 1 kHz - preserves SNR in wideband sensor signal chains (e.g., piezoelectric or microphone preamps). |
| Operating Temperature | −40°C to +125°C - qualified per AEC-Q100 Grade 1 for engine control units and transmission control modules. |
Pinout & Package
TLV2772QDRQ1 is housed in an 8-pin SOIC (D) package with standard pinout and thermal pad omitted. Pin functions are validated per TI SGLS179D datasheet Figure 3 (TLV2772 D/PW top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Inverting amplifier output; rail-to-rail swing supports full-scale ADC reference buffering. |
| 2 | IN1− | Inverting input; high 1012 Ω impedance minimizes loading on high-Z feedback networks. |
| 3 | IN1+ | Non-inverting input; common-mode range includes GND, enabling single-supply transducer interfaces. |
| 4 | GND | Analog ground reference; separate from digital ground in mixed-signal PCB layouts. |
| 5 | VDD | Positive supply; accepts 2.5–5.5 V; internal regulation ensures stable bias over automotive battery variation. |
| 6 | OUT2 | Second amplifier output; independently usable for dual-path signal conditioning (e.g., differential pair). |
| 7 | IN2− | Second inverting input; matched offset and drift to IN1− enable precision dual-opamp configurations. |
| 8 | IN2+ | Second non-inverting input; identical specs to IN1+; supports parallel or cascaded gain stages. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 100 mV of VDD/GND at 2.2 mA load - eliminates level-shifting in 3.3 V microcontroller ADC interfaces. |
| Micropower shutdown | IDD < 1 µA per channel - enables dynamic power gating in wake-on-event sensor nodes without external FETs. |
| Low THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets telecom line-driver requirements per ITU-T G.712. |
| High CMMR | 84 dB min at 25°C (VDD = 2.7 V) - rejects common-mode noise in motor current sensing with shunt resistors. |
| AEC-Q100 qualified | Grade 1 (−40°C to +125°C), HTOL tested - certified for safety-critical automotive subsystems without derating. |

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 |
|---|---|---|---|
| TLV2772AQDRQ1 | Lower max input offset voltage (1.6 mV vs. 2.7 mV), same package and pinout. | Better suited for ultra-precision current sensing where offset error must be minimized. | Select TLV2772AQDRQ1 when VIO budget is ≤ 1.6 mV; otherwise TLV2772QDRQ1 offers cost-optimized performance. |
| LM7332QMA/NOPB | Higher slew rate (18 V/µs), higher supply current (2.3 mA/ch), no shutdown, wider VDD range (2.7–36 V). | Preferred for high-voltage industrial motor control, not automotive-qualified. | Choose LM7332QMA/NOPB only if >10.5 V/µs slew rate is required and AEC-Q100 compliance is not mandatory. |
Compared with TLV2772AQDRQ1, the TLV2772QDRQ1 trades 1.1 mV higher VIO for lower cost and identical footprint; versus LM7332QMA/NOPB, it provides AEC-Q100 qualification and shutdown at the expense of slew rate and supply voltage headroom.

FAQ
What is the maximum operating supply voltage for TLV2772QDRQ1?
The absolute maximum supply voltage for TLV2772QDRQ1 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 permanent damage and invalidates AEC-Q100 qualification. At 5 V, TLV2772QDRQ1 achieves optimal slew rate (10.5 V/µs) and THD+N (0.005%).
Does TLV2772QDRQ1 support true rail-to-rail input?
No, TLV2772QDRQ1 features rail-to-rail *output* only. Its common-mode input voltage range extends to GND but does not reach VDD - specified as 0 V to (VDD − 1.3 V) at 25°C. For rail-to-rail input capability, consider TI's TLV9062-Q1, which is not pin-compatible with TLV2772QDRQ1.
How does the shutdown function operate on TLV2772QDRQ1?
TLV2772QDRQ1 has no dedicated shutdown pin; it is a non-shutdown variant within the TLV277x-Q1 family. The part number TLV2772QDRQ1 corresponds to the base dual op-amp without shutdown logic. For shutdown capability, use TLV2773QDRQ1 (dual with shared shutdown) or TLV2775QPWRQ1 (quad with individual shutdown pins).
What is the thermal resistance (θJA) of TLV2772QDRQ1 in SOIC-8 package?
The junction-to-ambient thermal resistance (θJA) for TLV2772QDRQ1 in SOIC-8 (D) package is 172.4°C/W, derived from its 725 mW power rating at TA ≤ 25°C and 5.8 mW/°C derating factor. This value assumes standard JEDEC 2-layer board layout; actual θJA improves with copper pour and thermal vias.
Is TLV2772QDRQ1 compatible with lead-free reflow profiles?
Yes, TLV2772QDRQ1 is RoHS-compliant and qualified for standard lead-free reflow per J-STD-020. Its moisture sensitivity level (MSL) is 2a, with floor life of 1 year at ≤30°C/60% RH. Peak reflow temperature is rated at 260°C for 10 seconds, matching IPC/JEDEC Class 3 requirements.
