Product details
Overview
TLV2770AID from Texas Instruments is a single-channel, rail-to-rail output CMOS operational amplifier optimized for automotive and industrial applications requiring high ac performance at low power. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage (max 1.6 mV over −40°C to 125°C), 2 pA input bias current, and operates from 2.5 V to 5.5 V supply - enabling precision signal conditioning in ADC driver and sensor front-end roles.
For engineers reviewing the TLV2770AID datasheet, TLV2770AID pinout, TLV2770AID application, or TLV2770AID equivalent, this page provides verified electrical specifications, MSOP-8 package details, temperature-rated performance data, and real-world design context for automotive-grade analog signal chains.
Technical Context
The TLV2770AID employs a CMOS input stage with micropower shutdown (IDD < 1 µA), enabling system-level power gating. Its rail-to-rail output swing supports full dynamic range utilization when driving SAR or sigma-delta ADC reference inputs across 2.5–5.5 V supplies.
Specified over −40°C to +125°C, it maintains 0.005% THD+N into 600 Ω and 17 nV/√Hz input noise voltage - making it suitable for high-fidelity analog paths in engine control units and battery management systems where dc precision and ac fidelity coexist under thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typ - enables accurate reproduction of fast transients in motor current sensing or active filter stages. |
| Gain-Bandwidth Product | 5.1 MHz typ - supports stable unity-gain buffer configurations up to ~5 MHz without phase margin degradation. |
| Input Offset Voltage | Max 1.6 mV over −40°C to 125°C - ensures ≤0.032% error in 50 mV sensor signal amplification at automotive extremes. |
| Supply Current per Channel | 1 mA typ at 2.7 V - allows integration into always-on subsystems with sub-10 µA quiescent budget per channel. |
| Rail-to-Rail Output | Swings within 100 mV of rails at 2.2 mA load - maximizes SNR when interfacing with 12-bit+ ADCs powered from same rail. |
| Input Bias Current | 2 pA max - preserves accuracy in high-impedance pH or thermocouple interfaces without external guard traces. |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets telecom-grade line driver requirements for voice-band signal integrity. |
Pinout & Package
TLV2770AID is housed in an 8-pin MSOP (DGK) package with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm. Pin 1 is marked by a beveled edge or molded dot; the device features no internal connection on pins 1, 5, and 8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - left unconnected; no routing required. |
| 2 | IN− | Inverting input - connects to feedback network or differential sensor leg. |
| 3 | IN+ | Non-inverting input - accepts high-impedance sensor or reference voltage. |
| 4 | GND | Analog ground reference - must tie to clean local ground plane beneath thermal pad. |
| 5 | NC | No internal connection - unused; avoid solder bridging. |
| 6 | VDD | Positive supply rail - decoupled with 100 nF ceramic capacitor placed ≤2 mm from pin. |
| 7 | OUT | Amplifier output - drives ADC input, filter stage, or low-side current sense node. |
| 8 | NC | No internal connection - electrically isolated; no PCB trace needed. |
Key Features

| Micropower shutdown mode | IDD < 1 µA enables firmware-controlled power cycling in battery-backed modules without leakage-induced drain. |
| Rail-to-rail output swing | Delivers >98% of full-scale output range into 2.2 mA loads - eliminates need for dual-supply generation in portable diagnostics. |
| Automotive temperature rating | Qualified per AEC-Q100 Grade 1 (−40°C to +125°C) - validated for under-hood ECU and ADAS sensor signal conditioning. |
| Low input noise voltage | 17 nV/√Hz at 10 kHz - preserves resolution in 24-bit delta-sigma ADC front-ends for precision current measurement. |
| High CMRR & PSRR | Min 70 dB CMRR and 70 dB PSRR over full temp range - rejects engine noise coupling and supply ripple in noisy vehicle environments. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2770ID | Same silicon, rated for −40°C to +125°C but with 2.5 mV max VIO (vs. 1.6 mV for TLV2770AID). | Acceptable for non-safety-critical automotive modules where tighter offset is not required. | Select TLV2770ID if cost sensitivity outweighs need for guaranteed 1.6 mV VIO in production BOMs. |
| OPA333AIDBVR | Zero-drift architecture; 10 µV max VIO, 0.1 µV/°C drift, but lower 350 kHz GBW and 0.16 V/µs slew rate. | Better for ultra-low-offset dc applications (e.g., strain gauge bridges), unsuitable for fast transient capture. | Choose OPA333AIDBVR only when dc stability dominates ac response requirements - not for ADC driver or PWM sensing. |
Compared with TLV2770ID, TLV2770AID offers tighter input offset (1.6 mV vs. 2.5 mV) critical for high-gain sensor interfaces; versus OPA333AIDBVR, it trades zero-drift precision for 15× higher slew rate and 14× greater bandwidth - making TLV2770AID optimal for mixed-signal automotive timing and transient capture.

FAQ
What is the maximum operating temperature range for TLV2770AID?
The TLV2770AID is qualified for continuous operation from −40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements for automotive under-hood applications. This rating is confirmed in the "recommended operating conditions" table of the SLOS209G datasheet, and applies across all electrical parameters unless otherwise noted in test conditions.
Does TLV2770AID support rail-to-rail input common-mode voltage range?
No, TLV2770AID does not support rail-to-rail input. Its common-mode input voltage range extends from GND to VDD − 1.3 V (e.g., 0 V to 3.7 V at VDD = 5 V), as specified in the "recommended operating conditions" section of the datasheet. The rail-to-rail capability applies only to the output stage, not the input stage.
What is the shutdown current consumption of TLV2770AID?
The TLV2770AID draws less than 1 µA per channel in shutdown mode (IDD(SHDN) = 0.8–1.5 µA typical, 1.3–2 µA max over −40°C to +125°C), as documented in the electrical characteristics tables for TLV277xAI grade devices. This enables ultra-low-power wake-up architectures in always-on automotive subsystems.
Which package variants are available for TLV2770AID?
The TLV2770AID is available exclusively in the 8-pin MSOP (DGK) package, as confirmed in the "TLV2770 and TLV2771 AVAILABLE OPTIONS" table on page 2 of SLOS209G. No SOIC, SOT-23, or PDIP variants are offered for the 'A' grade temperature version - only the DGK package is listed for TLV2770AID.
How does TLV2770AID's input offset voltage compare to TLV2770CD?
TLV2770AID guarantees a maximum input offset voltage of 1.6 mV over −40°C to +125°C, whereas TLV2770CD (commercial grade) specifies 2.5 mV max over 0°C to +70°C. This tighter 1.6 mV spec makes TLV2770AID suitable for high-accuracy automotive sensor interfaces where thermal drift must be minimized across full operating range.
