Product details
Overview
TLV2775CN from Texas Instruments is a quad-channel, rail-to-rail output CMOS operational amplifier optimized for single-supply operation (2.5 V to 5.5 V), delivering 5.1 MHz gain-bandwidth, 10.5 V/µs slew rate, and 360 µV input offset voltage - enabling high-fidelity signal conditioning in portable medical sensors and automotive analog front-ends.
For engineers reviewing the TLV2775CN datasheet, TLV2775CN pinout, TLV2775CN application, or TLV2775CN equivalent, this device supports precision low-voltage sensing, ADC driver stages with 600-Ω load capability, micropower shutdown mode (<1 µA per channel), and extended temperature operation up to 125°C - critical for industrial data acquisition and battery-powered instrumentation.
Technical Context
The TLV2775CN integrates four independent high-speed CMOS op-amps with rail-to-rail output swing, micropower shutdown control per pair (pins 1/2SHDN and 3/4SHDN), and robust dc precision including 2 pA input bias current and 17 nV/√Hz input noise voltage at 10 kHz. It operates across −40°C to 125°C with guaranteed performance at 2.7 V and 5 V supplies.
Its architecture enables stable unity-gain operation into 600-Ω loads with 0.005% THD+N, while maintaining 46° phase margin and 12 dB gain margin - making it suitable for driving SAR and sigma-delta ADC reference inputs without external buffering.

Pinout & Package
TLV2775CN is housed in a 16-pin plastic DIP (N) package with through-hole mounting and 0.3-inch body width. Pin 1 is located at the left end of the top row, identified by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1/2 Shutdown Control | Active-low enable for channels 1 and 2; pulls supply current to <1 µA when driven low. |
| 2 | 1OUT | Inverting amplifier output for channel 1; rail-to-rail swing supports full-scale ADC input drive. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad CMOS op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464CDR | Lower slew rate (1.6 V/µs), no shutdown, higher supply current (550 µA/channel), rail-to-rail I/O. | Better suited for general-purpose low-speed signal routing where power is not constrained. | Select TLV2464CDR only if shutdown functionality and >5-MHz bandwidth are unnecessary. |
| OPA4340UA | Higher precision (125 µV VIO), lower noise (7 nV/√Hz), no shutdown, 5.5-V max supply, SO-14 package. | Preferred for ultra-low-noise medical imaging front-ends requiring <0.1 µV/°C drift. | Choose OPA4340UA when dc accuracy outweighs micropower shutdown and 5.5-V operation. |
Compared with TLV2775CN, TLV2464CDR trades bandwidth and power control for cost and simplicity, while OPA4340UA prioritizes dc precision and noise over supply flexibility and integrated shutdown - making TLV2775CN optimal for battery-operated, wide-temperature, medium-bandwidth sensor interfaces.

FAQ
What is the maximum operating temperature for TLV2775CN?
The TLV2775CN is rated for continuous operation from −40°C to +125°C, meeting industrial and automotive under-hood requirements. Its electrical characteristics are fully specified across this range, including input offset voltage, CMRR, and supply current - ensuring reliable performance in harsh thermal environments without derating.
Does TLV2775CN support true rail-to-rail input?
No, TLV2775CN features rail-to-rail *output* swing only. Its common-mode input voltage range extends from GND to VDD − 1.3 V (at 2.7 V supply), meaning it cannot accept signals within 1.3 V of the positive rail. This limitation must be considered when designing single-supply non-inverting amplifiers with high gain.
How does the shutdown function work on TLV2775CN?
TLV2775CN has two independent shutdown controls: pin 1 (1/2SHDN) disables channels 1 and 2, and pin 13 (3/4SHDN) disables channels 3 and 4. Both are active-low; pulling either pin below 0.8 V (at VDD = 5 V) reduces the respective pair's supply current to <1 µA while preserving output state until re-enabled.
Can TLV2775CN drive a 600-Ω load with low distortion?
Yes, TLV2775CN delivers 0.005% THD+N when driving a 600-Ω load at 1 kHz with AV = 1, verified at 5 V supply. Its 10.5 V/µs slew rate and 2.2 mA output current capability ensure clean signal reproduction - making it suitable for telecom line drivers and audio codec interfacing where harmonic fidelity is critical.
What is the input bias current specification for TLV2775CN?
The TLV2775CN specifies a typical input bias current of 2 pA at 25°C, with a maximum of 100 pA across the full −40°C to +125°C temperature range. This ultra-low value minimizes voltage errors in high-impedance sensor interfaces, such as photodiode transimpedance amplifiers or pH electrode circuits.
