Product details
Overview
TLV2772CDGKR from Texas Instruments is a dual 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 at 5 V. It operates from 2.5 V to 5.5 V single supply and delivers low distortion (0.005% THD+N into 600 Ω) for precision signal conditioning in ADC driver and telecom interface circuits.
For engineers reviewing the TLV2772CDGKR datasheet, TLV2772CDGKR pinout, TLV2772CDGKR application, or TLV2772CDGKR equivalent, this device is selected for high-speed, low-power, rail-to-rail output amplification where input offset voltage (360 µV max), noise (17 nV/√Hz), and temperature stability (−40°C to 125°C) are critical design constraints.
Technical Context
The TLV2772CDGKR implements a CMOS input stage with 2 pA typical input bias current and 17 nV/√Hz input voltage noise at 10 kHz, enabling high-impedance sensor interfacing. Its unity-gain stable architecture supports 5.1 MHz bandwidth while maintaining 46° phase margin into 600 Ω with 100 pF capacitive load.
Rail-to-rail output swing (within 100 mV of rails at 2.2 mA) and micropower shutdown mode (<1 µA per channel) allow operation in portable and automotive systems requiring dynamic power control and wide dynamic range analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - enables direct integration with 3.3 V and 5 V logic domains without level-shifting. |
| Gain-Bandwidth Product | 5.1 MHz - supports stable closed-loop operation up to ~400 kHz at gain = 12 for anti-aliasing filter applications. |
| Slew Rate | 10.5 V/µs - ensures <0.6 µs settling to 0.01% for 2 V step, suitable for fast-settling data acquisition channels. |
| Input Offset Voltage | 360 µV max - minimizes DC error in precision transducer amplification and reference buffering. |
| THD+N @ 1 kHz | 0.005% into 600 Ω - meets telecom line-driver spectral purity requirements without external compensation. |
| Shutdown Current | <1 µA per channel - reduces system standby power by >99.9% versus active mode (1 mA). |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive and industrial control environments. |
Pinout & Package
TLV2772CDGKR is housed in an 8-pin MSOP (DGK) package with 0.65 mm pitch, 3.0 mm × 3.0 mm footprint, and exposed thermal pad (not electrically connected). Pin 1 is marked by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must be left floating or tied to GND for mechanical stability only. |
| 2 | Inverting Input (Ch1) | High-impedance CMOS node (10¹² Ω) - requires guarded trace routing to minimize leakage-induced offset drift. |
| 3 | Non-inverting Input (Ch1) | Matches Pin 2 impedance - balanced layout critical for common-mode rejection above 60 dB. |
| 4 | GND | Analog ground reference - must connect directly to low-impedance PCB ground plane, separate from digital return. |
| 5 | Shutdown (Ch1) | Active-high logic control - drives channel 1 into sub-µA shutdown when pulled ≥1.4 V (VDD-dependent threshold). |
| 6 | VDD | Positive supply - requires local 100 nF ceramic decoupling within 5 mm of pin to suppress 10.5 V/µs transient currents. |
| 7 | Inverting Input (Ch2) | Independent of Ch1 inputs - allows differential pair configuration without crosstalk (typical PSRR >70 dB). |
| 8 | Non-inverting Input (Ch2) | Electrically identical to Pin 3 - supports matched dual-channel instrumentation topologies. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 100 mV of VDD/GND at ±2.2 mA - eliminates need for negative supply in single-supply data acquisition systems. |
| Micropower shutdown | Reduces IDD to <1 µA per channel - enables battery-powered devices to extend runtime during idle intervals. |
| Low input bias current | 2 pA typical - preserves signal integrity in high-Z pH sensors, photodiode transimpedance, and piezoelectric interfaces. |
| Low THD+N | 0.005% into 600 Ω - satisfies ITU-T G.712 telecom linearity specs without post-amplifier filtering. |
| Extended temperature range | Specified from −40°C to 125°C - supports AEC-Q100 Grade 2 compliance for engine control and ADAS subsystems. |

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 |
|---|---|---|---|
| TLV2462CDR | Lower slew rate (1.6 V/µs), higher supply current (550 µA), I/O rail-to-rail, 6.4 MHz GBW | Better DC precision (250 µV VIO) but insufficient speed for >100 kHz closed-loop use | Select when ultra-low offset and lower power dominate over speed; not suitable for ADC driving above 200 kSPS. |
| OPA2350UA | Higher slew rate (20 V/µs), higher supply current (4.9 mA), rail-to-rail output only, 38 MHz GBW | Superior AC performance but 5× higher quiescent power and no shutdown mode | Choose for high-fidelity audio or fast pulse amplification where power budget allows; incompatible with battery-operated designs. |
Compared with TLV2772CDGKR, TLV2462CDR trades speed for lower offset and power, while OPA2350UA delivers 2× slew rate and 7× bandwidth at the cost of 5× supply current and no power-down capability - making TLV2772CDGKR optimal for cost-sensitive, thermally constrained, or duty-cycled applications.

FAQ
What is the maximum operating temperature range for the TLV2772CDGKR?
The TLV2772CDGKR is rated for operation from −40°C to +125°C ambient temperature, meeting industrial and automotive Grade 2 requirements. This range is validated per the datasheet's recommended operating conditions and applies to the C-suffix commercial-grade variant packaged in MSOP (DGK). Derating curves for power dissipation are provided in the Dissipation Rating Table.
Does the TLV2772CDGKR support true rail-to-rail input operation?
No, the TLV2772CDGKR features rail-to-rail *output* swing but not rail-to-rail input. Its common-mode input voltage range extends from GND to VDD − 1.3 V at 2.7 V supply, meaning the upper limit is 1.4 V - not the full rail. For full rail-to-rail input capability, consider TI's TLV2472 or OPA2320 families.
How does the shutdown function operate on the TLV2772CDGKR?
The TLV2772CDGKR has independent shutdown control for each channel via Pin 5 (Ch1) and Pin 10 (Ch2, though not present in DGK package). For TLV2772CDGKR (8-pin MSOP), only Channel 1 shutdown is accessible. The threshold is approximately 1.4 V at 2.7 V supply and scales with VDD; asserting ≥1.4 V places that channel in sub-1 µA shutdown state while leaving the other channel active.
Can the TLV2772CDGKR drive a 10 kΩ load with rail-to-rail output swing?
Yes - the TLV2772CDGKR guarantees rail-to-rail output swing into 10 kΩ loads (VOH ≥ VDD − 100 mV and VOL ≤ 100 mV at 2.2 mA). However, into 600 Ω, output swing is reduced to ~VDD − 200 mV / 200 mV due to internal output stage headroom limitations. Load impedance directly impacts achievable swing and THD+N performance.
Is the TLV2772CDGKR pin-compatible with other TLV277x variants in MSOP packages?
Yes - all TLV277x dual-channel variants (TLV2772x) in 8-pin MSOP (DGK) share identical pinout: Pins 1–8 correspond to NC, IN−(Ch1), IN+(Ch1), GND, SHDN(Ch1), VDD, IN−(Ch2), IN+(Ch2). This allows drop-in replacement between TLV2772CDGKR, TLV2772IDGKR, and TLV2772AQDGKR, provided temperature and offset specifications align with system requirements.
