Product details
Overview
TLV2774CN from Texas Instruments is a quad CMOS rail-to-rail output operational amplifier optimized for single-supply portable and automotive systems. 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 signal conditioning in ADC driver and telecom line-driver applications.
For engineers reviewing the TLV2774CN datasheet, TLV2774CN pinout, TLV2774CN application, or TLV2774CN equivalent, key selection considerations include its 14-pin PDIP package, −40°C to 125°C temperature range (I-suffix), rail-to-rail output swing into 600-Ω loads, 0.005% THD+N at 1 kHz, and micropower shutdown mode (<1 µA per channel).
Technical Context
The TLV2774CN uses a CMOS input stage with 2 pA typical input bias current and 17 nV/√Hz input noise voltage, supporting precision measurement and low-noise analog front-ends. Its unity-gain-stable architecture achieves 46° phase margin with 600-Ω load and 100-pF capacitive load, ensuring robust stability in sensor interface and active filter designs.
It features independent shutdown control for channels 1/2 and 3/4 (pins 8 and 15), enabling dynamic power management in multi-stage signal chains. The device is characterized across extended temperature ranges and supports rail-to-rail output swing within 100 mV of each rail at 2.2 mA load - critical for low-voltage data acquisition systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2774IDR | Same electrical specs, but in 14-pin SOIC package with surface-mount footprint and higher thermal performance (θJA = 120°C/W vs. 70°C/W for PDIP) | Better suited for space-constrained PCBs and automated assembly; not compatible with through-hole layouts | Select TLV2774IDR for new SMT designs requiring improved power dissipation and smaller board area |
| OPA4340UA | Lower input offset (125 µV max), lower noise (8 nV/√Hz), but higher supply current (750 µA/channel) and no shutdown function | Preferred for ultra-precision DC-coupled applications where power budget allows; lacks dynamic power control | Choose OPA4340UA when sub-200 µV offset and <10 nV/√Hz noise are mandatory, and shutdown is unnecessary |
Compared with TLV2774IDR, TLV2774CN offers proven mechanical reliability in legacy through-hole systems and simplified hand-soldering, while OPA4340UA trades power efficiency for superior DC precision - making TLV2774CN optimal for cost-sensitive, thermally stable, and maintenance-friendly industrial modules.

FAQ
What is the maximum supply voltage rating for TLV2774CN?
The absolute maximum supply voltage for TLV2774CN is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation above 5.5 V risks parametric degradation and reduced reliability. All electrical characteristics in the datasheet are specified between 2.7 V and 5 V, with guaranteed performance across this band at temperatures from −40°C to +125°C. Exceeding 5.5 V voids warranty and may cause permanent damage.
Does TLV2774CN support true rail-to-rail input operation?
No, TLV2774CN features rail-to-rail *output* swing only. Its input common-mode voltage range extends from GND to VDD − 1.3 V (e.g., 0 V to 3.7 V at 5 V supply), meaning it cannot accept signals at the positive rail. This limitation is clearly defined in the "Recommended Operating Conditions" table. For full rail-to-rail input capability, TI recommends alternatives such as the TLV2464 or OPA4340 - but TLV2774CN's output stage remains fully rail-to-rail, delivering 0 V to VDD swing under 2.2 mA load.
How does the shutdown function work on TLV2774CN?
TLV2774CN has two independent shutdown pins: pin 8 (1/2SHDN) controls Channels 1 and 2, and pin 15 (3/4SHDN) controls Channels 3 and 4. Driving either pin low (≤0.8 V) enables the corresponding pair; driving it high (≥2.0 V) places those amplifiers into micropower shutdown with IDD < 1 µA per channel. Both shutdown paths are internally pulled down, so unconnected pins default to active mode. No external pull-up is required unless active-low logic control is needed.
Can TLV2774CN drive a 600-Ω load at full rail-to-rail swing?
Yes, TLV2774CN is explicitly characterized driving 600-Ω loads with 0.005% THD+N at 1 kHz and maintains rail-to-rail output swing within 100 mV of each rail at ±2.2 mA output current. At 5 V supply, VOH ≥ 4.7 V and VOL ≤ 0.21 V are guaranteed under these conditions. This makes TLV2774CN suitable for telecom line drivers, audio codecs, and other applications requiring low-distortion, high-current output into standard impedances - without external buffer stages.
Is TLV2774CN qualified for automotive applications?
Yes, TLV2774CN is offered in the I-suffix grade (TLV2774IN), which is qualified to AEC-Q100 Grade 2 (−40°C to +105°C) and supports extended operation up to +125°C. While the CN suffix denotes commercial temperature range (0°C to 70°C), the I-suffix variant shares identical electrical specs and pinout. For automotive use, specify TLV2774IN - not TLV2774CN - to ensure qualification documentation, PPAP support, and guaranteed lot traceability per automotive quality standards.
