Product details
Overview
TLV2770AIDR from Texas Instruments is a single-channel, rail-to-rail output CMOS operational amplifier optimized for precision, low-power, and high-speed analog signal conditioning. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage (max), 1 mA supply current per channel, and operates from 2.5 V to 5.5 V - enabling use in battery-powered sensor front-ends and automotive ADC driver circuits.
For engineers reviewing the TLV2770AIDR datasheet, TLV2770AIDR pinout, TLV2770AIDR application, or TLV2770AIDR equivalent, key selection considerations include its −40°C to 125°C extended temperature rating, micropower shutdown mode (<1 µA), 17 nV/√Hz input noise, and compatibility with 600-Ω telecom loads at 0.005% THD+N.
Technical Context
The TLV2770AIDR employs a CMOS input stage with 2 pA typical input bias current and 10¹² Ω differential input resistance, supporting high-impedance sensor interfacing. Its rail-to-rail output stage drives ±2.2 mA into 600 Ω while maintaining 0.005% THD+N at 1 kHz - critical for high-fidelity signal acquisition.
It features an integrated micropower shutdown control (SHDN pin) that reduces supply current to <1 µA, with fast turnon/turnoff times of 1.2 µs and 335 ns respectively. The device is characterized across −40°C to 125°C and qualified for automotive applications per AEC-Q100 requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typ - enables accurate reproduction of fast-changing signals up to ~1.7 MHz full-power bandwidth |
| Gain-Bandwidth Product | 5.1 MHz typ - supports stable unity-gain and moderate closed-loop gains (e.g., G = 10 up to 500 kHz) |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤0.07% error in 0.5 V full-scale 12-bit measurement systems |
| Supply Current | 1 mA per channel - allows dual-channel operation within 2 mA total, suitable for portable instrumentation |
| Input Noise Voltage | 17 nV/√Hz at 10 kHz - minimizes contribution to system noise floor in precision amplification stages |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets telecom-grade linearity for voice/data interface circuits |
| Operating Temp Range | −40°C to 125°C - validated for under-hood automotive and industrial control environments |
Pinout & Package
TLV2770AIDR is packaged in an 8-pin SOIC (D package) with exposed pad (not thermally enhanced). Pinout follows standard single-amplifier configuration with dedicated shutdown control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must be left floating or tied to GND per layout best practice |
| 2 | IN− | Inverting input - high-impedance CMOS node (2 pA bias current); sensitive to PCB leakage |
| 3 | IN+ | Non-inverting input - matched to IN− for optimal common-mode rejection |
| 4 | GND | Analog ground reference - requires low-impedance connection to system AGND plane |
| 5 | SHDN | Active-low shutdown enable - pulls IDD to <1 µA when driven low; high-Z when open |
| 6 | VDD | Positive supply - accepts 2.5 V to 5.5 V; bypass with 0.1 µF ceramic capacitor to GND |
| 7 | OUT | Amplifier output - rail-to-rail swing (within 100 mV of rails at 2.2 mA load) |
| 8 | NC | No internal connection - must be left floating or tied to GND |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 100 mV of VDD and GND at 2.2 mA load - maximizes dynamic range in single-supply systems |
| Micropower shutdown | IDD < 1 µA in shutdown - extends battery life in intermittent-sampling sensor nodes |
| Low distortion at 600 Ω | 0.005% THD+N - preserves signal integrity in telecom line drivers and CODEC interfaces |
| High CMMR & PSRR | 84 dB CMRR / 89 dB PSRR - rejects power supply ripple and common-mode interference in noisy environments |
| Extended temperature grade | Qualified from −40°C to 125°C - supports automotive engine control, ADAS sensor signal chains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture; 0.1 µV/°C offset drift vs. TLV2770AIDR's 2 µV/°C; 17 µV max VIO vs. 360 µV | Better DC accuracy for long-term stable measurements; lower 1/f noise but 3.8 MHz GBW vs. 5.1 MHz | Choose OPA333AIDBVR for ultra-low drift applications (e.g., precision weigh scales); TLV2770AIDR preferred where speed/noise trade-off favors higher slew rate and lower cost |
| LMV721IDBVR | Lower supply current (425 µA vs. 1 mA); 1.5 V/µs slew rate; no shutdown function; 1.8 V to 5.5 V supply | Optimized for ultra-low-power sensor nodes without shutdown need; insufficient slew for fast-settling ADC drivers | Choose LMV721IDBVR only for always-on, low-bandwidth (<200 kHz), sub-500 µA systems; TLV2770AIDR required when shutdown, speed, or THD+N specs are mandatory |
Compared with OPA333AIDBVR and LMV721IDBVR, TLV2770AIDR uniquely balances 5.1 MHz bandwidth, 10.5 V/µs slew rate, rail-to-rail output, and micropower shutdown - making it the only option among the three qualified for automotive AEC-Q100 and capable of driving 600-Ω loads at 0.005% THD+N.

FAQ
What is the maximum operating temperature range for TLV2770AIDR?
The TLV2770AIDR is rated for continuous operation from −40°C to +125°C ambient temperature. This extended range is verified per TI's characterization data and qualifies the device for under-hood automotive applications and industrial control environments where thermal stress is significant. The "I" suffix explicitly denotes this industrial/automotive grade.
Does TLV2770AIDR support true rail-to-rail input?
No, TLV2770AIDR features rail-to-rail *output* only. Its common-mode input voltage range extends from GND to VDD − 1.3 V (at VDD = 2.7 V), meaning it cannot accept signals within 1.3 V of the positive rail. Input common-mode range is not rail-to-rail, unlike some newer TI amplifiers such as the TLV9061.
What is the typical supply current of TLV2770AIDR in active mode?
The TLV2770AIDR draws 1 mA typical supply current per channel at VDD = 2.7 V and TA = 25°C, with a maximum of 2 mA across the full −40°C to 125°C temperature range and supply voltage (2.5 V to 5.5 V). This value is confirmed in the Electrical Characteristics tables on pages 6 and 8 of the SLOS209G datasheet.
Can TLV2770AIDR drive a 600-Ω load with low distortion?
Yes - the TLV2770AIDR is specifically characterized for 600-Ω loading, delivering 0.005% THD+N at 1 kHz with AV = 1. This performance is guaranteed across temperature and supply voltage, making it suitable for telecom line drivers and audio interface circuits where harmonic distortion must remain below −86 dBc.
Is TLV2770AIDR pin-compatible with other TLV277x family members?
No - TLV2770AIDR (single-channel, 8-pin SOIC with SHDN) is not pin-compatible with TLV2771 (5-pin SOT-23), TLV2772 (dual, 8-pin SOIC), or TLV2774 (quad, 14-pin SOIC). Its 8-pin D-package pinout (NC, IN−, IN+, GND, SHDN, VDD, OUT, NC) is unique to the TLV2770 variant and requires dedicated PCB layout.
