Product details
Overview
TLV2772CDGK from Texas Instruments is a dual-channel CMOS rail-to-rail output operational amplifier optimized for single-supply operation (2.5 V to 5.5 V), delivering 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, and 360 µV input offset voltage. It drives 600-Ω loads with 0.005% THD+N and supports automotive-grade temperature range (−40°C to 125°C) in an 8-pin MSOP package.
For engineers reviewing the TLV2772CDGK datasheet, TLV2772CDGK pinout, TLV2772CDGK application, or TLV2772CDGK equivalent, key selection considerations include its micropower shutdown mode (<1 µA per channel), low 17 nV/√Hz input noise, and compatibility with precision analog front-ends in portable instrumentation and automotive sensor signal conditioning.
Technical Context
The TLV2772CDGK employs a CMOS input stage with 2 pA input bias current and rail-to-rail output swing, enabling full dynamic range utilization in low-voltage systems. Its high slew rate and bandwidth are achieved without compromising dc precision-evidenced by 360 µV max input offset and 84 dB CMRR at 25°C.
It operates across a wide supply range (2.5 V–5.5 V) and features internal compensation for unity-gain stability with 600-Ω load and 100-pF capacitive load. The device includes no shutdown functionality in the CDGK variant (C-suffix, DGK package), distinguishing it from TLV2772 variants with SHDN pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typ - enables fast settling for 12-bit ADC driving at ≥100 kSPS |
| Gain-Bandwidth Product | 5.1 MHz typ - supports closed-loop gains up to 10× with >500 kHz small-signal bandwidth |
| Input Offset Voltage | 360 µV max - ensures ≤0.01% error in 3.3-V full-scale precision sensor amplification |
| Supply Current (per channel) | 1 mA typ - allows dual op-amp operation within 2 mA total budget for battery-powered devices |
| Input Noise Voltage | 17 nV/√Hz @ 10 kHz - preserves SNR in audio and sensor signal chains above 1 kHz |
| THD+N | 0.005% @ 1 kHz, RL = 600 Ω - meets telecom line-driver distortion requirements |
| Rail-to-Rail Output | Swings within 100 mV of rails @ 1.3 mA - maximizes usable output range in 3.3-V or 5-V systems |
Pinout & Package
TLV2772CDGK is housed in an 8-pin MSOP (DGK) package with exposed thermal pad (not electrically connected). Pin 1 is marked by a beveled edge or molded dot; the package measures 3.0 mm × 3.0 mm × 1.0 mm (max height).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must be left floating or grounded per layout best practice |
| 2 | IN− (Ch1) | Inverting input for Channel 1 - high-impedance CMOS node (2 pA bias current) |
| 3 | IN+ (Ch1) | Non-inverting input for Channel 1 - referenced to GND or bias network |
| 4 | GND | Analog ground reference - requires low-impedance connection to system ground plane |
| 5 | VDD | Positive supply (2.5 V–5.5 V) - bypass with 100 nF ceramic capacitor near pin |
| 6 | OUT (Ch1) | Channel 1 output - capable of ±50 mA short-circuit current, rail-to-rail swing |
| 7 | IN− (Ch2) | Inverting input for Channel 2 - independent of Ch1; shares same VDD/GND |
| 8 | IN+ (Ch2) | Non-inverting input for Channel 2 - fully differential dual-channel configuration |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full 0–VDD dynamic range at 1.3 mA load, critical for maximizing ADC input utilization |
| Low input bias current (2 pA) | Minimizes voltage error in high-impedance sensor interfaces (e.g., pH electrodes, photodiode transimpedance) |
| High slew rate + bandwidth synergy | 10.5 V/µs slew with 5.1 MHz GBW enables accurate reproduction of fast 100-kHz sine waves |
| Specified over −40°C to 125°C | Validated performance for under-hood automotive applications and industrial control environments |
| Low THD+N into 600 Ω | 0.005% distortion supports clean signal transmission in telecom line drivers and audio buffers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462CDR | Lower slew rate (1.6 V/µs), higher supply current (550 µA/ch), I/O rail-to-rail, wider VDD (2.7–6 V) | Better dc precision (250 µV VIO), but insufficient bandwidth for >100-kHz signal paths | Select when ultra-low offset and lower power dominate over speed; not suitable for ADC driver or telecom roles. |
| OPA2340UA | Higher slew rate (6 V/µs), lower noise (12 nV/√Hz), same 5.5-V max VDD, SO-8 package only | Superior ac performance but lacks extended temperature rating (−40°C to 125°C not guaranteed) | Prefer for lab-grade instrumentation where ambient temperature is controlled; avoid for automotive deployment. |
Compared with TLV2772CDGK, TLV2462CDR trades bandwidth for lower offset and power, while OPA2340UA improves noise and speed but sacrifices automotive qualification - making TLV2772CDGK the only option qualified for both high-speed precision and harsh-environment operation.

FAQ
What is the operating temperature range for TLV2772CDGK?
The TLV2772CDGK is rated for operation from 0°C to 70°C (C-suffix). This commercial-grade temperature range is validated per the datasheet SLOS209G and applies to all electrical specifications unless otherwise noted. It is not rated for automotive (−40°C to 125°C) or military (−55°C to 125°C) extremes - those require TLV2772IDGK or TLV2772MDGK variants respectively.
Does TLV2772CDGK include a shutdown feature?
No, TLV2772CDGK does not include a shutdown function. The CDGK variant uses the standard 8-pin MSOP pinout without SHDN terminals. Shutdown capability is present only in TLV2772 variants with "S" suffixes (e.g., TLV2772CDSG) or in the TLV2773/TLV2775 families. For TLV2772CDGK, supply current remains at ~1 mA per channel during active operation.
What is the maximum capacitive load TLV2772CDGK can drive while remaining stable?
TLV2772CDGK is unity-gain stable driving up to 100 pF with a 600-Ω load, as verified in the datasheet's operating characteristics (SLOS209G, page 9). Driving >100 pF requires external isolation resistance (e.g., 10–50 Ω in series with the output) to maintain phase margin >46° and prevent peaking or oscillation.
Can TLV2772CDGK operate from a 2.5-V supply?
Yes, TLV2772CDGK is fully specified and functional at VDD = 2.5 V. Key parameters-including 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth, and rail-to-rail output swing-are characterized down to 2.5 V (see datasheet Sections 6–9). Input common-mode range extends to GND, and output swings within 100 mV of each rail at 1.3 mA load.
Is TLV2772CDGK pin-compatible with other TLV277x variants in MSOP-8?
Yes, TLV2772CDGK shares identical pinout and footprint with all TLV2772 variants in DGK (MSOP-8) packaging-including TLV2772IDGK and TLV2772AQDGK. All use the same 8-pin configuration: NC, IN−, IN+, GND, VDD, OUT, IN−, IN+. However, absolute maximum ratings and operating conditions differ by temperature grade, so electrical validation per application environment remains essential.
