Product details
Overview
TLV2775AIN from Texas Instruments is a quad-channel, rail-to-rail output CMOS operational amplifier optimized for automotive and industrial applications. It delivers 5.1 MHz gain-bandwidth, 10.5 V/µs slew rate, 360 µV input offset voltage (typ), 1 mA per channel supply current, 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.
For engineers reviewing the TLV2775AIN datasheet, TLV2775AIN pinout, TLV2775AIN application, or TLV2775AIN equivalent, this page provides verified electrical specifications, temperature-rated performance (−40°C to 125°C), shutdown functionality (IDD < 1 µA), and package-specific layout guidance for the 16-pin PDIP (N) variant.
Technical Context
The TLV2775AIN implements a CMOS input stage with 2 pA 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 enables full dynamic range utilization when driving SAR or sigma-delta ADC reference inputs.
It features independent shutdown control for channels 1/2 and 3/4 (pins 8 and 15), allowing selective power gating without affecting active amplifiers. The device is characterized across −40°C to 125°C and qualified to AEC-Q100 for automotive use.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2775IDR | Same electrical specs but in 16-pin SOIC (D) package; no through-hole mounting. | Preferred for automated SMT assembly; not suitable for prototyping or legacy through-hole PCBs. | Select TLV2775IDR only if board design uses SOIC footprint and reflow capability exists. |
| OPA2377AIDR | Lower 3.5 MHz GBW, 1.5 V/µs slew rate, but lower 7 nV/√Hz noise and 10 µV offset (max). | Better for ultra-low-noise DC applications; insufficient for >200-kHz signal bandwidths. | Choose OPA2377AIDR when offset and noise dominate over speed; avoid for ADC driver roles requiring >500-kHz settling. |
Compared with TLV2775IDR, TLV2775AIN offers identical AC/DC performance but enables manual assembly and high-voltage creepage in legacy designs; versus OPA2377AIDR, it trades noise/offset for 3× higher bandwidth and 7× faster slew rate - critical for time-domain fidelity in sensor sampling.

FAQ
What is the maximum operating temperature for TLV2775AIN?
The TLV2775AIN is rated for continuous operation from −40°C to +125°C ambient temperature. This specification is validated per AEC-Q100 Grade 2 requirements and applies across the full 2.5 V to 5.5 V supply range. Thermal derating begins above 70°C per the dissipation rating table in the datasheet, with 92 mW maximum power at 125°C for the N-package.
Does TLV2775AIN support true rail-to-rail input?
No, TLV2775AIN features rail-to-rail *output* only. Its common-mode input voltage range extends from GND to VDD − 1.3 V (at 2.7 V supply), meaning the input cannot accept signals within 1.3 V of VDD. For example, at 5 V supply, valid input range is 0 V to 3.7 V. This limitation is explicitly defined in the "Recommended Operating Conditions" table of the TLV2775AIN datasheet.
How does the shutdown function work on TLV2775AIN?
The TLV2775AIN has two independent shutdown pins: pin 8 (1/2SHDN) disables Channels 1 and 2, while pin 15 (3/4SHDN) disables Channels 3 and 4. A logic-high voltage (>2.0 V at VDD = 5 V) activates shutdown, reducing supply current per channel to <1.5 µA (typ). Both outputs go to high-impedance state; inputs remain active. Full functionality resumes within 1.9 µs after shutdown deactivation.
Can TLV2775AIN drive a 600-Ω load with low distortion?
Yes, TLV2775AIN is specifically characterized for 600-Ω loads: at 1 kHz, it achieves 0.005% THD+N (typ) with AV = 1, and 0.016% THD+N (typ) with AV = 10 at 5 V supply. This performance meets telecom line-driver requirements and supports high-fidelity signal routing to test equipment inputs without external buffering.
What is the input bias current specification for TLV2775AIN?
The TLV2775AIN exhibits 2 pA typical input bias current (IIB) at 25°C, with a maximum of 100 pA across the full −40°C to +125°C operating range. This ultra-low value enables accurate amplification of high-impedance sources such as photodiodes, piezoelectric sensors, and thermocouples without significant voltage error or drift.
