Product details
Overview
TLV2772AQPW 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, and 360 µV input offset voltage at 5 V supply, with micropower shutdown (<1 µA per channel) and operation across −40°C to 125°C. It drives ADC reference inputs and telecom line drivers requiring low THD+N (0.005% into 600 Ω).
For engineers reviewing the TLV2772AQPW datasheet, TLV2772AQPW pinout, TLV2772AQPW application, or TLV2772AQPW equivalent, this page provides verified electrical specifications, TSSOP-8 package layout, automotive-grade thermal performance, and real-world design context for precision analog signal conditioning in harsh environments.
Technical Context
The TLV2772AQPW employs a high-speed CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, enabling accurate low-level signal amplification without significant DC error or noise degradation. Its rail-to-rail output swing supports full dynamic range utilization in single-supply systems down to 2.5 V.
It integrates independent shutdown control per channel (active-low), allowing selective power gating in multi-stage analog chains. The device is characterized over extended temperature and supply ranges, with guaranteed performance at VDD = 2.7 V and 5 V, and common-mode input range extending to within 0.3 V of rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typical - enables clean amplification of fast transient signals up to ~1.6 MHz full-power bandwidth into 10 kΩ load. |
| Gain-Bandwidth Product | 5.1 MHz typical - supports stable unity-gain and moderate-gain configurations (e.g., G = 10 up to ~500 kHz) with phase margin ≥46°. |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤0.072% gain error in 5 V full-scale sensor interfaces without trimming. |
| Supply Current (per channel) | 1 mA typical at 5 V - allows dual op-amp operation within 2 mA total, suitable for battery-powered automotive modules. |
| Shutdown Current | <1 µA per channel - reduces system standby power by >99.9% when unused channels are disabled. |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets audio-grade line driver requirements for infotainment and telematics subsystems. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood and ADAS ECU applications per AEC-Q100 stress test requirements. |
Pinout & Package
TSSOP-8 (PW) package: 3.0 mm × 4.4 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 | OUT1 | Inverting configuration output; capable of sourcing/sinking ±2.2 mA while maintaining rail-to-rail swing. |
| 2 | IN−1 | Inverting input; high-impedance CMOS node (10¹² Ω) with 2 pA bias current for minimal loading on feedback networks. |
| 3 | IN+1 | Non-inverting input; matched to IN−1 for optimal common-mode rejection (CMRR ≥82 dB). |
| 4 | GND | Analog ground reference; must be low-impedance connection to minimize PSRR degradation and noise coupling. |
| 5 | VDD | Positive supply rail; operates from 2.5 V to 5.5 V; bypass capacitor (0.1 µF) required at pin for stability. |
| 6 | IN+2 | Non-inverting input of second amplifier; electrically isolated from Channel 1 except via shared supply and ground. |
| 7 | IN−2 | Inverting input of second amplifier; identical DC and AC specs to Channel 1 for matched dual-channel performance. |
| 8 | OUT2 | Output of second amplifier; independently configurable; no internal cross-coupling between channels. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2772IPW | Same architecture and specs, but rated for −40°C to 125°C industrial temp range (I-suffix), not automotive Q-grade. | Lacks AEC-Q100 qualification and extended reliability screening; unsuitable for safety-critical automotive use. | Select TLV2772IPW only for cost-sensitive industrial designs where automotive qualification is unnecessary. |
| OPA2333AIPW | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2772AQPW's 2 µV/°C; higher 350 kHz GBW but lower 1.7 V/µs slew rate. | Better long-term DC stability in temperature-varying environments; insufficient slew for fast-settling ADC buffering or telecom line driving. | Choose OPA2333AIPW when ultra-low drift dominates over speed; avoid when >1 V/µs slew or <0.6 µs settling is required. |
Compared with TLV2772IPW, the TLV2772AQPW adds automotive qualification and tighter VIO distribution, while OPA2333AIPW trades speed for near-zero drift-making TLV2772AQPW optimal for high-fidelity, high-speed automotive analog signal paths where both precision and bandwidth matter.

FAQ
What is the maximum operating supply voltage for TLV2772AQPW?
The absolute maximum supply voltage for TLV2772AQPW is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation above 5.5 V risks permanent damage and violates AEC-Q100 stress limits. At 5 V, TLV2772AQPW achieves its specified 10.5 V/µs slew rate and 5.1 MHz gain-bandwidth product.
Does TLV2772AQPW support true rail-to-rail input?
No, TLV2772AQPW features rail-to-rail *output* only. Its common-mode input voltage range extends to within 0.3 V of GND and up to VDD − 1.3 V (e.g., 0 V to 3.7 V at 5 V supply). Input signals beyond this range cause increased offset error and reduced CMRR, so external level-shifting may be needed for full-rail input applications.
How does the shutdown function work on TLV2772AQPW?
TLV2772AQPW has no dedicated shutdown pin; it is a non-shutdown variant within the TLV2772 family. The "AQPW" suffix denotes automotive-grade TSSOP-8 packaging without integrated shutdown logic. For shutdown capability, select TLV2773AQPW (dual + shutdown) or TLV2775AQPW (quad + shutdown).
Is TLV2772AQPW pin-compatible with other TLV2772 variants in TSSOP-8?
Yes, TLV2772AQPW shares identical pinout and footprint with all TLV2772x PW-package variants (e.g., TLV2772CDPW, TLV2772IDPW, TLV2772IPW). All use the standard TSSOP-8 pin assignment: OUT1, IN−1, IN+1, GND, VDD, IN+2, IN−2, OUT2 - confirmed in TI SLOS209G Figure 4.
What is the thermal resistance (θJA) of TLV2772AQPW in TSSOP-8 package?
The junction-to-ambient thermal resistance (θJA) for TLV2772AQPW in TSSOP-8 (PW) package is 5.6 mW/°C derating factor, with a maximum power rating of 700 mW at TA ≤ 25°C. This yields θJA ≈ 143°C/W, assuming standard JEDEC 2-layer board layout per TI SLOS209G Dissipation Rating Table.
