Product details
Overview
TLV2772CDR from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for single-supply operation (2.5 V to 5.5 V), delivering 10.5 V/µs slew rate and 5.1 MHz gain-bandwidth product while consuming only 1 mA per channel. It features 360 µV input offset voltage, 17 nV/√Hz input noise, and micropower shutdown mode (<1 µA), making it suitable for precision analog front-ends in portable instrumentation and automotive sensor signal conditioning.
For engineers reviewing the TLV2772CDR datasheet, TLV2772CDR pinout, TLV2772CDR application, or TLV2772CDR equivalent, key selection considerations include its rail-to-rail output swing into 600-Ω loads (0.005% THD+N), extended temperature range (0°C to 70°C), and availability in SOIC-8 package with verified pin compatibility across the TLV277x family.
Technical Context
The TLV2772CDR employs a CMOS input stage with 2 pA input bias current and high differential input resistance (>10¹² Ω), enabling low-error amplification of high-impedance sources. Its unity-gain-stable architecture supports capacitive loads up to 100 pF while maintaining 46° phase margin and 12 dB gain margin at 5 V supply.
It operates over a 2.5–5.5 V supply range with rail-to-rail output swing (within 100 mV of rails at 2.2 mA load) and specified common-mode input range from GND to VDD − 1.3 V. Input offset voltage drift is 2 µV/°C, and total harmonic distortion plus noise remains ≤0.005% driving 600-Ω at 1 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Pinout & Package
TLV2772CDR is packaged in an 8-pin SOIC (Small Outline Integrated Circuit) surface-mount package with standard JEDEC MS-012AC footprint (5.3 mm × 6.2 mm, 1.27 mm pitch). Pin 1 is marked by a beveled edge or molded dot.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input, Channel 1 | High-impedance node for feedback network connection; accepts signals down to GND. |
| 2 | Non-inverting Input, Channel 1 | High-Z input for reference or sensor signal; common-mode range extends to GND. |
| 3 | Output, Channel 1 | Rail-to-rail capable output; drives 600-Ω loads with <0.005% THD+N at 1 kHz. |
| 4 | Ground (GND) | Common return path for both channels; requires low-inductance PCB tie to system ground plane. |
| 5 | Non-inverting Input, Channel 2 | Independent high-Z input; electrically isolated from Channel 1 inputs per datasheet layout guidance. |
| 6 | Inverting Input, Channel 2 | Separate feedback node; supports independent gain configuration per channel. |
| 7 | Output, Channel 2 | Second rail-to-rail output; identical AC/DC specs to Pin 3; enables dual-path signal processing. |
| 8 | Positive Supply (VDD) | Single supply input; accepts 2.5–5.5 V; decoupling capacitor (0.1 µF) required adjacent to this pin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA | Higher 16 V/µs slew rate but higher 1.6 mA/channel supply current; no shutdown mode. | Better for wideband active filters; less suitable for battery-powered systems requiring ultra-low quiescent power. | Choose OPA2340UA when bandwidth >10 MHz and supply current <1.5 mA is not mandatory. |
| MCP6022-I/SN | Lower 2.8 MHz GBW and 1.5 V/µs slew rate; 170 µV max offset; 1.2 mA/channel. | Optimized for low-cost general-purpose use; insufficient for high-fidelity audio or fast-settling ADC drivers. | Select MCP6022-I/SN where cost sensitivity outweighs need for 5.1 MHz bandwidth and 10.5 V/µs slew rate. |
Compared with TLV2772CDR, OPA2340UA trades higher power for greater speed, while MCP6022-I/SN reduces cost and performance-making TLV2772CDR the optimal balance of precision, speed, and micropower efficiency in 0°C–70°C industrial and portable designs.

FAQ
What is the maximum operating temperature range for TLV2772CDR?
The TLV2772CDR is rated for operation from 0°C to 70°C (C-suffix), as confirmed in the "Recommended Operating Conditions" table of the SLOS209G datasheet. It is not qualified for extended temperature ranges like the I-suffix (−40°C to 125°C) or M-suffix (−55°C to 125°C) variants. This makes TLV2772CDR appropriate for commercial and industrial indoor applications but not under-hood automotive or military environments.
Does TLV2772CDR support shutdown mode?
No, TLV2772CDR does not include a shutdown function. The datasheet confirms that only TLV2770, TLV2773, and TLV2775 variants feature shutdown pins (e.g., SHDN on Pin 5 for TLV2770). TLV2772CDR has no dedicated shutdown terminal and draws ~1 mA per channel continuously when powered. For micropower shutdown capability, consider TLV2773CDR instead.
What is the input common-mode voltage range for TLV2772CDR?
Per the "Recommended Operating Conditions" section of the TLV2772CDR datasheet, the input common-mode voltage range is GND to VDD − 1.3 V at 2.7 V and 5 V supplies. For example, at VDD = 3.3 V, inputs may range from 0 V to 2.0 V. This excludes rail-to-rail input capability but supports ground-referenced sensor signals and mid-supply biasing schemes.
Is TLV2772CDR pin-compatible with other TLV277x family members in SOIC-8?
Yes, TLV2772CDR shares identical SOIC-8 pinout (D package) with TLV2772IDR and TLV2772AIDR, as shown in Figure 4 of SLOS209G. All TLV2772-x variants in D package use the same 1-IN−, 2-IN+, 3-OUT1, 4-GND, 5-IN+, 6-IN−, 7-OUT2, 8-VDD assignment. This allows drop-in replacement across temperature grades without PCB redesign.
What load drive capability does TLV2772CDR provide?
TLV2772CDR delivers ±50 mA short-circuit output current (absolute maximum rating) and sustains rail-to-rail swing into 600-Ω loads with 0.005% THD+N at 1 kHz. At 2.2 mA load, output voltage swings within 100 mV of each rail (e.g., 0.21 V low, 4.7 V high at VDD = 5 V), enabling direct interface with legacy telecom line standards and 12-bit ADC reference buffers.
