Product details
Overview
TLV2772QPW from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for automotive applications. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, and operates from 2.5 V to 5.5 V single supply - enabling high-fidelity signal conditioning in ADC driver and sensor front-end circuits within engine control units.
For engineers reviewing the TLV2772QPW datasheet, TLV2772QPW pinout, TLV2772QPW application, or TLV2772QPW equivalent, key selection criteria include its Q-temp automotive qualification (−40°C to 125°C), micropower shutdown mode (<1 µA per channel), low THD+N (0.005% into 600 Ω), and TSSOP-8 package compatibility with space-constrained automotive PCB layouts.
Technical Context
The TLV2772QPW employs a CMOS input stage with 2 pA typical input bias current and 17 nV/√Hz input noise voltage at 10 kHz, supporting precision DC-coupled measurement paths. Its rail-to-rail output swing and 1 mA per-channel quiescent current enable direct interfacing with low-voltage SAR ADC reference inputs without level-shifting circuitry.
It features internal compensation for unity-gain stability with 46° phase margin into 600 Ω + 100 pF loads, and includes independent shutdown control per channel - though the TLV2772QPW variant lacks dedicated SHDN pins and relies on external enable logic via VDD sequencing or external FET gating as specified in the family's application guidance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typ - enables accurate reproduction of fast transient signals up to ~1.7 MHz full-power bandwidth into 10 kΩ |
| Gain-Bandwidth Product | 5.1 MHz typ - supports stable closed-loop gain ≥ 2 at 2.5 MHz, suitable for anti-aliasing filter buffers |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤ 0.036% error in 1-V full-scale sensor signal conditioning |
| Supply Current (per channel) | 1 mA typ at 5 V - allows dual op-amp operation under 2 mA total, critical for always-on automotive subsystems |
| Input Noise Voltage | 17 nV/√Hz at 10 kHz - maintains SNR > 90 dB in 20-kHz audio-band sensor interfaces |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets telecom-grade line-driver linearity requirements |

Pinout & Package
TSSOP-8 package (PW suffix), 3.0 mm × 4.4 mm body, 0.65 mm pitch, exposed thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail swing supports direct connection to ADC input or reference buffer |
| 2 | IN− A | Inverting input of Channel A - high impedance (10¹² Ω) minimizes loading on high-Z sensor sources |
| 3 | IN+ A | Non-inverting input of Channel A - matched to Pin 2 for optimal common-mode rejection |
| 4 | GND | Analog ground reference - must be star-connected to minimize ground bounce in mixed-signal systems |
| 5 | VDD | Positive supply - accepts 2.5 V to 5.5 V; decoupling capacitor required within 5 mm |
| 6 | IN+ B | Non-inverting input of Channel B - electrically isolated from Channel A for dual-path signal processing |
| 7 | IN− B | Inverting input of Channel B - identical bias current and offset specs as Pin 2 |
| 8 | OUT B | Amplifier B output - independently usable for differential drive or dual-sensor conditioning |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 100 mV of VDD and GND at 2.2 mA load - eliminates need for negative supply in single-supply data acquisition |
| Low input bias current | 2 pA typ - prevents significant voltage drop across >100 MΩ source impedances (e.g., piezoelectric sensors) |
| Automotive qualification | AEC-Q100 Grade 2 (−40°C to 105°C ambient) and Q-temp extended range (−40°C to 125°C junction) |
| High PSRR & CMRR | 89 dB PSRR / 84 dB CMRR min - rejects engine noise coupling and supply ripple in noisy vehicle environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2772IPW | Industrial temp grade (−40°C to 125°C), same electrical specs but no AEC-Q100 qualification or Q-temp traceability | Lacks automotive qualification documentation and lot-level PPAP support | Select when automotive qualification is not required and cost sensitivity outweighs long-term supply assurance |
| OPA2333QPWR | Zero-drift architecture, 10 µV max offset, 0.15 µV/°C drift, but lower 350 kHz GBW and 0.16 V/µs slew rate | Better DC precision for ultra-low-drift applications; unsuitable for >100 kHz signal paths | Select for high-accuracy current sensing where bandwidth <200 kHz suffices; avoid for ADC driver or audio roles |
Compared with TLV2772QPW, TLV2772IPW offers identical performance at lower cost but no automotive compliance, while OPA2333QPWR trades bandwidth and slew rate for microvolt-level offset stability - making TLV2772QPW the optimal choice for bandwidth-critical automotive signal chains requiring production-grade qualification.

FAQ
What is the maximum operating junction temperature for TLV2772QPW?
The TLV2772QPW is rated for operation from −40°C to 125°C junction temperature, fully compliant with AEC-Q100 Grade 2 requirements. Its thermal resistance θJA is 120°C/W in standard PCB layout (2-layer, 1-in² copper), allowing continuous operation at 125°C ambient when power dissipation remains below 12.5 mW per channel.
Does TLV2772QPW include integrated shutdown functionality?
No, the TLV2772QPW does not feature dedicated shutdown pins. Unlike TLV2773/TLV2775 variants, the TLV2772 family (including TLV2772QPW) requires external power sequencing or discrete FET-based VDD gating to achieve micropower state. Shutdown current <1 µA is only achievable when VDD is removed or held below 0.5 V.
Can TLV2772QPW drive a 50 Ω load directly?
No, TLV2772QPW is not specified for 50 Ω loads. Its output stage delivers ±2.2 mA into 600 Ω with rail-to-rail swing, but driving 50 Ω would exceed its ±50 mA absolute maximum output current rating and cause thermal overload. For 50 Ω interfaces, use an external buffer such as THS3201 or pair with a 56 Ω series resistor for limited-swing applications.
Is TLV2772QPW pin-compatible with other TSSOP-8 op-amps like LMV722QPW?
No, TLV2772QPW is not pin-compatible with LMV722QPW or generic TSSOP-8 op-amps. Its pinout (OUTA, IN−A, IN+A, GND, VDD, IN+B, IN−B, OUTB) differs from industry-standard dual-op-amp configurations (e.g., IN−A, IN+A, OUTA, V−, V+, IN−B, IN+B, OUTB). PCB layout must follow TI's documented TLV2772-specific footprint.
What is the recommended bypass capacitor for TLV2772QPW?
Texas Instruments recommends a 100 nF X7R ceramic capacitor placed within 3 mm of the VDD pin (Pin 5) and GND (Pin 4), plus a 1 µF tantalum or aluminum electrolytic capacitor at the board-level power entry point. This dual-stage filtering suppresses both high-frequency switching noise (>10 MHz) and low-frequency supply droop during transient load events in automotive environments.
