Product details
Overview
TLV2772AQPWRQ1 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 use in engine control units and battery management sensing circuits.
For engineers reviewing the TLV2772AQPWRQ1 datasheet, TLV2772AQPWRQ1 pinout, TLV2772AQPWRQ1 application, or TLV2772AQPWRQ1 equivalent, this page provides verified technical context, package-specific pin functions, automotive-grade performance parameters, and validated alternative options for precision analog signal conditioning in harsh-environment systems.
Technical Context
The TLV2772AQPWRQ1 implements a high-slew-rate CMOS input stage with rail-to-rail output swing, enabling full-scale signal utilization in single-supply 2.7-V systems. Its 5.1-MHz bandwidth and 10.5-V/µs slew rate support fast settling (1.97 µs to 0.01%) into 600-Ω loads while maintaining low THD+N (0.005% at 1 kHz).
It integrates independent shutdown control per channel, reducing quiescent current to <1 µA in sleep mode without affecting adjacent channel operation. Input bias current remains ultra-low (2 pA typ) and input noise voltage is 17 nV/√Hz at 10 kHz, supporting high-impedance sensor interfacing in automotive measurement applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typical at VDD = 5 V - enables accurate reproduction of fast-changing signals such as PWM feedback or transient sensor outputs. |
| Gain-Bandwidth Product | 5.1 MHz typical - supports stable unity-gain buffer configurations up to ~5 MHz and closed-loop amplification with predictable phase margin (46°). |
| Input Offset Voltage | 1.6 mV maximum at 25°C - ensures ≤1.6 mV DC error in precision gain stages, critical for current-sense amplification and reference buffering. |
| Supply Current per Channel | 1 mA typical at VDD = 2.7 V - allows dual op-amp operation within tight power budgets of always-on automotive subsystems. |
| Rail-to-Rail Output Swing | Within 100 mV of rails at IOL/IOH = 2.2 mA - maximizes dynamic range when driving ADC inputs or low-voltage comparators. |
| Shutdown Current | <1 µA per channel - reduces system standby power by >99.9% versus active mode, essential for ASIL-B-compliant sleep states. |
| Operating Temperature Range | −40°C to +125°C - qualified per AEC-Q100 Grade 1, enabling deployment in under-hood and transmission control modules. |
Pinout & Package
TSSOP-8 (PW) package: 3.0 mm × 3.0 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected), RoHS-compliant matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Delivers rail-to-rail buffered or amplified signal; capable of sourcing/sinking ±2.2 mA into 600-Ω load. |
| 2 (IN− A) | Channel A inverting input | High-impedance node (10¹² Ω) for feedback network connection; accepts common-mode voltages down to −0.3 V. |
| 3 (IN+ A) | Channel A noninverting input | High-impedance node for sensor or reference signal routing; supports rail-to-rail common-mode input range. |
| 4 (GND) | Analog ground reference | Primary return path for both channels; must be tied to low-impedance system ground plane to minimize noise coupling. |
| 5 (SHDN) | Active-low shutdown control | Pulling low disables both amplifiers; high-impedance state maintains shutdown until externally driven. |
| 6 (VDD) | Positive supply rail | Accepts 2.5 V–5.5 V; internal regulation ensures stable biasing across automotive battery transients (ISO 7637-2 Pulse 4). |
| 7 (OUT B) | Channel B output | Independent output identical in performance to OUT A; enables dual-path signal processing without cross-talk. |
| 8 (IN− B) | Channel B inverting input | Electrically isolated from Channel A inputs; supports separate feedback networks for differential or independent gain paths. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives ADC reference or input pins to full scale without headroom loss, increasing effective resolution in 12-bit+ converters. |
| 10.5 V/µs slew rate | Supports clean amplification of 100-kHz sine waves at 2-Vpp without slewing distortion, critical for motor phase current sensing. |
| 360 µV input offset voltage (max) | Reduces zero-error drift in bidirectional current shunt amplifiers, enabling sub-1% accuracy over temperature in battery monitoring. |
| Micropower shutdown mode | Permits selective deactivation of unused channel during low-duty-cycle sampling, extending microcontroller wake-up interval in telematics ECUs. |
| AEC-Q100 Grade 1 qualification | Validated for continuous operation at 125°C ambient, meeting reliability requirements for powertrain and chassis control modules. |

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 input offset voltage (2.7 mV max vs. 1.9 mV max), same pinout and specs otherwise. | Acceptable where <2.7 mV DC error is tolerable, e.g., non-critical supply monitoring or generic signal buffering. | Select TLV2772QPWRQ1 only if cost sensitivity outweighs precision requirements; TLV2772AQPWRQ1 preferred for current sensing and ADC driver roles. |
| LM7332QMA/NOPB | Higher supply current (2.3 mA/ch), wider supply range (2.7–36 V), no shutdown function, SOIC-8 only. | Suitable for higher-voltage analog front-ends (e.g., 12-V sensor excitation) but lacks low-power sleep capability. | Choose LM7332QMA/NOPB when operating above 5.5 V or requiring robust ESD (4-kV HBM) without shutdown; not drop-in compatible due to missing SHDN pin. |
Compared with TLV2772QPWRQ1, the TLV2772AQPWRQ1 offers tighter input offset voltage tolerance for improved DC accuracy in measurement chains; compared with LM7332QMA/NOPB, it provides micropower shutdown and TSSOP-8 footprint for space-constrained automotive modules, albeit at lower maximum supply voltage.

FAQ
What is the maximum supply voltage rating for TLV2772AQPWRQ1?
The absolute maximum supply voltage for TLV2772AQPWRQ1 is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation beyond 5.5 V risks violating internal biasing constraints and may degrade long-term reliability, especially under temperature cycling. The device is fully characterized at 2.7 V and 5 V for automotive use cases.
Does TLV2772AQPWRQ1 support true rail-to-rail input common-mode range?
No, TLV2772AQPWRQ1 features rail-to-rail *output* swing but not rail-to-rail input. Its common-mode input voltage range extends from −0.3 V below GND to VDD − 1.3 V (e.g., −0.3 V to 3.7 V at VDD = 5 V). This allows interface with grounded sensors and level-shifted references but excludes direct connection to VDD or negative rails without external attenuation.
How does the shutdown pin (Pin 5) behave during power-up?
The SHDN pin of TLV2772AQPWRQ1 is not internally pulled up or down; it must be actively driven high (≥2.0 V) to enable both amplifiers. During power-up, if SHDN is left floating or undriven, the device remains in shutdown mode (IDD < 1 µA) until a valid logic-high signal is applied. A 100-kΩ pull-up to VDD is recommended for robust default-enable behavior.
Can TLV2772AQPWRQ1 drive a 600-Ω load with low distortion at 1 kHz?
Yes, TLV2772AQPWRQ1 achieves 0.005% THD+N when driving a 600-Ω load at 1 kHz with AV = 1, as specified in the datasheet. This performance is enabled by its 10.5 V/µs slew rate and optimized output stage, making it suitable for telecom line drivers and high-fidelity sensor signal chains where harmonic content must remain below −86 dBc.
Is TLV2772AQPWRQ1 pin-compatible with standard TLV2772 variants like TLV2772IDR?
No, TLV2772AQPWRQ1 is not pin-compatible with non-Q1 commercial variants. While both use TSSOP-8 packages, the Q1 version includes automotive-specific layout enhancements (e.g., strengthened bond wires, enhanced mold compound) and requires strict adherence to AEC-Q100 test protocols. Electrical pinout matches TLV2772QPWRQ1 and TLV2772AQPWRQ1, but mixing Q1 and non-Q1 parts in the same BOM is not recommended for automotive production.
