Product details
Overview
TLV2775AIDR from Texas Instruments is a quad CMOS operational amplifier with rail-to-rail output, 5.1 MHz gain-bandwidth, 10.5 V/µs slew rate, and micropower shutdown mode (IDD < 1 µA). It operates from 2.5 V to 5.5 V single supply and delivers 360 µV max input offset voltage and 0.005% THD+N driving 600-Ω loads - ideal for precision analog front-ends in automotive sensor signal conditioning.
For engineers reviewing the TLV2775AIDR datasheet, TLV2775AIDR pinout, TLV2775AIDR application, or TLV2775AIDR equivalent, key selection criteria include its −40°C to 125°C extended temperature rating, 16-pin SOIC package with integrated shutdown control per channel, low 17 nV/√Hz input noise, and verified performance at 2.7 V and 5 V supplies for battery-powered industrial and automotive systems.
Technical Context
The TLV2775AIDR implements a CMOS input stage with 2 pA typical input bias current and 10¹² Ω differential input resistance, enabling high-impedance sensor interfacing. Its rail-to-rail output stage supports full-swing operation into 600-Ω loads while maintaining 0.005% THD+N at 1 kHz - critical for telecom line drivers and ADC reference buffers.
Each of the four amplifiers features independent shutdown control (pins 1/2SHDN and 3/4SHDN), allowing dynamic power management. The device is characterized across −40°C to 125°C with guaranteed 360 µV input offset voltage and 2 µV/°C drift, meeting Q100 requirements for automotive applications.

Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full 0 V to VDD range at 2.2 mA load - eliminates need for dual supplies in ADC driver stages |
| Quad independent shutdown | Four dedicated SHDN pins allow per-channel power gating - reduces system idle current by >99% vs. always-on operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2774AIDR | No shutdown functionality; identical pinout and electrical specs except missing SHDN pins | Suitable where continuous operation is required and power gating is unnecessary | Select TLV2774AIDR if system-level power sequencing eliminates need for per-channel shutdown control |
| OPA4340UA | Higher 5.5 MHz GBW but higher 750 µA/ch supply current; no shutdown mode; different pinout (14-pin SOIC) | Better high-frequency precision but incompatible PCB layout and higher quiescent power | Choose OPA4340UA only when 10x lower noise (8 nV/√Hz) justifies 75% higher supply current and board redesign |
Compared with TLV2774AIDR, TLV2775AIDR adds independent shutdown control per channel without sacrificing bandwidth or noise - making it superior for duty-cycled sensor arrays. Versus OPA4340UA, TLV2775AIDR trades 27 nV/√Hz higher input noise for 75% lower supply current and automotive temperature qualification.

FAQ
What is the operating temperature range for TLV2775AIDR?
The TLV2775AIDR is specified for operation from −40°C to 125°C, meeting AEC-Q100 Grade 2 requirements for automotive under-hood applications. This range is validated across all key parameters including input offset voltage, CMRR, and supply current - ensuring reliable performance in extreme thermal environments without derating.
Does TLV2775AIDR support true rail-to-rail input?
No, TLV2775AIDR features rail-to-rail *output* only. Its common-mode input voltage range extends from GND to VDD − 1.3 V (at VDD = 5 V), meaning it cannot accept signals within 1.3 V of the positive rail. This limitation is explicitly documented in the Recommended Operating Conditions table on page 5 of the SLOS209G datasheet.
How does the shutdown function work on TLV2775AIDR?
TLV2775AIDR has two dedicated shutdown pins: pins 1/2SHDN control channels 1 and 2, and pins 15/16 (3/4SHDN) control channels 3 and 4. Each pair is active-high; driving the pin to VDD enables the channel, while pulling it to GND disables it and reduces that channel's supply current to <1 µA. All four channels remain functional when all SHDN pins are high.
What is the maximum capacitive load TLV2775AIDR can drive stably?
TLV2775AIDR is characterized for stable operation with up to 100 pF capacitive load in unity-gain configuration, as confirmed by phase margin (46°) and gain margin (12 dB) measurements in the Operating Characteristics tables (pages 7 and 9). Driving larger loads requires external isolation resistors or compensation per TI Application Report SLOA020.
Is TLV2775AIDR pin-compatible with other TLV277x variants?
TLV2775AIDR shares the same 16-pin SOIC (D) package and pinout with TLV2774AIDR and TLV2775CDR, but is *not* pin-compatible with TLV2775AIP (16-pin PDIP) or any TSSOP/PW variants. The SOIC version maintains consistent pin mapping across C/I/AI temperature grades, enabling drop-in replacement within the same package footprint.
