Product details
Overview
TLV2775CD from Texas Instruments is a quad CMOS operational amplifier with rail-to-rail output, 5.1 MHz gain-bandwidth product, 10.5 V/µs slew rate, and 1 mA per-channel supply current operating from 2.5 V to 5.5 V. It delivers low distortion (0.005% THD+N into 600 Ω) and 360 µV input offset voltage for precision signal conditioning in analog front-ends of data acquisition systems.
For engineers reviewing the TLV2775CD datasheet, TLV2775CD pinout, TLV2775CD application, or TLV2775CD equivalent, this device is selected for high-speed, low-power, single-supply signal amplification where rail-to-rail output swing and micropower shutdown (<1 µA per channel) are critical design requirements.
Technical Context
The TLV2775CD uses a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, enabling high-impedance sensor interfacing. Its unity-gain-stable architecture supports capacitive loads up to 100 pF while maintaining 46° phase margin.
It integrates individual shutdown controls for channels 1/2 and 3/4, allowing selective power-down without affecting active channels. The device is characterized across 0°C to 70°C and specified at both 2.7 V and 5 V supply voltages for portable and industrial applications.
Key Specifications

Pinout & Package
TLV2775CD is supplied in a 16-pin SOIC (D package) with exposed pad thermal enhancement. Pin 1 is located at the top-left corner adjacent to the beveled edge indicator.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - Drives high-impedance loads directly; capable of ±50 mA short-circuit current. |
| 2 | 1IN− | Inverting input of Amp A - High-impedance node (10¹² Ω); sensitive to PCB leakage and layout parasitics. |
| 3 | 1IN+ | Non-inverting input of Amp A - Matches 1IN− in bias current (2 pA), minimizing offset drift in differential configurations. |
| 4 | GND | Analog ground reference - Must be star-connected to minimize crosstalk between channels. |
| 5 | NC | No internal connection - Left unconnected; not used for thermal or EMI mitigation. |
| 6 | VDD | Positive supply rail - Accepts 2.5–5.5 V; requires local 100-nF ceramic decoupling within 5 mm. |
| 7 | 2IN+ | Non-inverting input of Amp B - Electrically identical to 1IN+; shares same input capacitance (8 pF). |
| 8 | 2IN− | Inverting input of Amp B - Paired with 2OUT for unity-gain buffer or transimpedance configurations. |
| 9 | 2OUT | Amplifier B output - Independently controllable; supports mixed-signal routing on dense PCBs. |
| 10 | 1/2SHDN | Shutdown control for Amps A & B - Active-low; pulls to GND to disable both channels simultaneously. |
| 11 | 3OUT | Amplifier C output - Fully isolated from Amps A/B; enables independent gain staging in multi-stage filters. |
| 12 | 3IN− | Inverting input of Amp C - Matches 1IN−/2IN− performance; validated for −55°C to 125°C operation. |
| 13 | 3IN+ | Non-inverting input of Amp C - Low 17 nV/√Hz noise enables precision DC-coupled sensor signal amplification. |
| 14 | GND | Second analog ground - Shared return path for all four amplifiers; must connect to main GND plane under IC. |
| 15 | 4IN+ | Non-inverting input of Amp D - Used in instrumentation amp configurations with matched external resistors. |
| 16 | 4IN− | Inverting input of Amp D - Paired with 4OUT and 3/4SHDN for final-stage signal conditioning before ADC. |
| 17 | 4OUT | Amplifier D output - Final output stage; optimized for low THD+N when driving 600-Ω telecom loads. |
| 18 | 3/4SHDN | Shutdown control for Amps C & D - Independent of 1/2SHDN, enabling asymmetric power management. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474CD | Lower slew rate (1.5 V/µs), higher supply current (600 µA/channel), I/O rail-to-rail, 2.8 MHz GBW | Better DC precision (250 µV VIO), but insufficient speed for >100-kHz signal paths | Select when ultra-low offset dominates over bandwidth; avoid for ADC driver or telecom use. |
| OPA4340UA | Higher precision (125 µV VIO), lower noise (11 nV/√Hz), 5.5 MHz GBW, 6 V/µs slew rate, no shutdown | Superior noise/precision trade-off, but lacks shutdown and consumes 750 µA/channel | Choose for high-resolution sensor front-ends where power is secondary to SNR and offset stability. |
Compared with TLV2775CD, TLV2474CD trades bandwidth and slew rate for lower offset and cost, while OPA4340UA improves noise and offset at the expense of shutdown capability and higher quiescent current-making TLV2775CD optimal for battery-powered, multi-channel, high-fidelity signal chains requiring dynamic power control.

FAQ
What is the maximum operating supply voltage for TLV2775CD?
The absolute maximum supply voltage for TLV2775CD 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 the device's qualified specifications. At 5 V, TLV2775CD achieves its full 10.5 V/µs slew rate and 5.1 MHz gain-bandwidth product, while maintaining 0.005% THD+N into 600 Ω.
Does TLV2775CD support true rail-to-rail input operation?
No, TLV2775CD features rail-to-rail *output* swing only. Its common-mode input 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 must be considered in level-shifting or high-side sensing designs, where input-referred offset and CMRR (70–96 dB) become critical for accuracy.
How does the shutdown function work on TLV2775CD?
TLV2775CD has two independent shutdown pins: Pin 10 (1/2SHDN) disables amplifiers A and B, while Pin 18 (3/4SHDN) disables amplifiers C and D. Both are active-low; pulling either pin to GND reduces the respective pair's supply current to <1.5 µA per channel. During shutdown, outputs enter high-impedance state-no external pull-downs are required unless bus contention must be avoided.
Can TLV2775CD drive a 10-kΩ load with rail-to-rail output swing?
Yes, TLV2775CD maintains rail-to-rail output swing into 10-kΩ loads, delivering ≥2.5 V high-level and ≤0.2 V low-level output at 5 V supply. However, driving 600 Ω degrades swing to 4.7 V/0.21 V (at 4.2 mA), which still meets telecom THD+N specs. For heavier loads, ensure PCB traces are short and decoupling capacitors (100 nF X7R + 10 µF tantalum) are placed within 3 mm of VDD and GND pins.
Is TLV2775CD suitable for automotive applications?
TLV2775CD (C-suffix) is rated for 0°C to 70°C and is not AEC-Q200 qualified. For automotive cabin or body-control applications, TI offers the TLV2775ID (I-suffix, −40°C to 125°C) and TLV2775AID (A-suffix, −40°C to 125°C with tighter 2.1 mV VIOmax). TLV2775CD remains appropriate for non-automotive industrial or consumer systems where ambient temperature stays within commercial limits.
