Product details
Overview
TLV2774CD from Texas Instruments is a quad CMOS rail-to-rail output operational amplifier optimized for single-supply portable and precision analog signal conditioning. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, 1 mA per-channel supply current, and operates from 2.5 V to 5.5 V - enabling high-fidelity sensor front-ends and ADC driver stages in battery-powered medical and industrial data acquisition systems.
For engineers reviewing the TLV2774CD datasheet, TLV2774CD pinout, TLV2774CD application, or TLV2774CD equivalent, key selection considerations include its rail-to-rail output swing into 600-Ω loads (0.005% THD+N), −55°C to 125°C military-grade temperature characterization, micropower shutdown mode (<1 µA/channel), and SOIC-14 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2774CD employs a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, supporting high-impedance sensor interfacing without significant loading or noise degradation. Its unity-gain-stable architecture achieves 46° phase margin driving 600-Ω loads with 100 pF capacitive load, ensuring robust settling (0.6 µs to 0.01%) in closed-loop configurations.
Designed for single-supply operation, the device features rail-to-rail output swing (within 100 mV of rails at 2.2 mA load) and common-mode input range extending to GND, eliminating level-shifting requirements when interfacing with low-voltage microcontrollers and SAR ADC reference inputs.

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 |
|---|---|---|---|
| TLV2474CD | Lower slew rate (1.5 V/µs), I/O rail-to-rail, higher supply current (600 µA/channel), no shutdown | Better DC precision (250 µV VIO), but insufficient speed for >100 kHz sensor signals or ADC drivers | Select TLV2474CD only when ultra-low offset dominates over bandwidth and power constraints |
| OPA4340UA | Higher precision (125 µV VIO), lower noise (11 nV/√Hz), no shutdown, SOIC-14, 5.5 V max supply | Superior for high-resolution data loggers; lacks micropower shutdown and military temp range | Choose OPA4340UA when 16-bit+ resolution is mandatory and shutdown functionality is unnecessary |
Compared with TLV2474CD and OPA4340UA, the TLV2774CD uniquely balances high-speed (5.1 MHz GBW), micropower shutdown (<1 µA), and extended temperature operation (−55°C to 125°C) - making it the only option among the three qualified for automotive under-hood and military embedded use cases requiring both performance and ruggedness.

FAQ
What is the maximum supply voltage for TLV2774CD?
The absolute maximum supply voltage for TLV2774CD 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 TI's specified conditions; design margins should maintain VDD ≤ 5.5 V under all transient and steady-state conditions. The TLV2774CD datasheet confirms reliable operation at 2.7 V and 5 V, with full parameter characterization across that span.
Does TLV2774CD support true rail-to-rail input?
No, TLV2774CD features rail-to-rail *output* but not rail-to-rail *input*. Its common-mode input voltage range extends to GND but stops 1.3 V below VDD (e.g., 0 V to 3.7 V at VDD = 5 V). This allows GND-referenced sensor interfaces but excludes direct sensing of signals near VDD without attenuation or level shifting. The TLV2774CD specification sheet explicitly defines VICR as "GND to VDD − 1.3 V" under recommended operating conditions.
Is TLV2774CD pin-compatible with other TLV277x variants?
TLV2774CD is pin-compatible with TLV2774ID and TLV2774AID in the same SOIC-14 package, but not with TLV2772 (8-pin) or TLV2775 (16-pin) variants. Pinouts differ across channel count and shutdown capability - e.g., TLV2775 adds dedicated shutdown pins, while TLV2774CD has no shutdown function (as confirmed by "-" in the FAMILY PACKAGE TABLE for TLV2774 under SHUTDOWN column). Always verify pin mapping using the official TLV2774CD pinout diagram, not generic family diagrams.
What is the typical input bias current of TLV2774CD?
The typical input bias current of TLV2774CD is 2 pA at 25°C, with a maximum of 100 pA across the full operating temperature range (0°C to 70°C for C-suffix). This ultra-low value minimizes voltage errors in high-impedance sensor circuits (e.g., pH electrodes or piezoelectric transducers) and enables stable operation with feedback resistors up to 10 MΩ without significant offset drift. The TLV2774CD datasheet specifies this under "Electrical Characteristics at VDD = 2.7 V".
Can TLV2774CD drive a 600-Ω load with low distortion?
Yes, TLV2774CD is specifically characterized to drive 600-Ω loads with 0.005% THD+N at 1 kHz, as stated in the datasheet's "Operating Characteristics" table. This performance is achieved using its rail-to-rail output stage and high slew rate (10.5 V/µs), making it suitable for telecom line drivers and audio applications where harmonic fidelity is critical. Load testing was performed under VDD = 5 V with AV = 1 configuration, confirming usability in legacy analog infrastructure interfaces.
