Product details
Overview
TLV2772IDGKR from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for precision, low-power, single-supply operation across −40°C to 125°C. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, 1 mA per channel supply current, and 17 nV/√Hz input noise voltage - enabling high-fidelity signal conditioning in automotive sensor front-ends and portable data acquisition systems.
For engineers reviewing the TLV2772IDGKR datasheet, TLV2772IDGKR pinout, TLV2772IDGKR application, or TLV2772IDGKR equivalent, key selection criteria include its rail-to-rail output swing at 2.5–5.5 V supply, micropower shutdown mode (<1 µA), low THD+N (0.005% into 600 Ω), and MSOP-8 package compatibility with space-constrained industrial and automotive PCB layouts.
Technical Context
The TLV2772IDGKR employs a CMOS input stage with 2 pA input bias current and 10¹² Ω differential input resistance, supporting high-impedance sensor interfacing. Its unity-gain-stable architecture achieves 46° phase margin with 600 Ω load and 100 pF capacitive load, ensuring robust stability in ADC driver and active filter configurations.
It features independent shutdown control per channel (SHDN pins), enabling dynamic power management in multi-stage analog signal chains. The device is characterized for operation from 2.5 V to 5.5 V, with rail-to-rail output swing delivering >99% of full-scale voltage range at 1.35 V headroom from each rail under 2.2 mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typ - enables accurate reproduction of fast-changing signals up to ~1.7 MHz full-power bandwidth into 10 kΩ load. |
| Gain-Bandwidth Product | 5.1 MHz typ - supports stable closed-loop gain ≥10 at 500 kHz, suitable for anti-aliasing filters and precision instrumentation amplifiers. |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤0.014% gain error in 2.5 V full-scale 12-bit systems without trimming. |
| Supply Current (per channel) | 1 mA typ at 2.7 V - allows dual op-amp operation within 2 mA total, critical for battery-powered sensor nodes. |
| Rail-to-Rail Output | Swings within 100 mV of rails at 2.2 mA load - maximizes dynamic range when driving SAR ADC reference inputs or DAC buffers. |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets telecom-grade audio and precision measurement linearity requirements. |
| Shutdown Current | <1 µA per channel - reduces system standby power by >99.9% versus active mode, extending battery life. |
Pinout & Package
TLV2772IDGKR is housed in an 8-pin MSOP (DGK) package, 3.0 mm × 3.0 mm × 1.0 mm, with exposed thermal pad (non-electrical). Pin 1 marked by beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Inverting amplifier output - drives loads up to ±50 mA; rail-to-rail swing supports direct interface to 12-bit ADC inputs. |
| 2 | IN−1 | Inverting input - high-impedance CMOS node (10¹² Ω); requires matched trace impedance for noise immunity in differential sensing. |
| 3 | IN+1 | Non-inverting input - referenced to GND or virtual ground; used for unity-gain buffer or sensor excitation feedback. |
| 4 | GND | Analog ground return - must be star-connected to minimize ground bounce between channels and digital sections. |
| 5 | SHDN1 | Channel 1 shutdown control - logic-high (>1.4 V) enables; logic-low (<0.6 V) disables with <1 µA quiescent draw. |
| 6 | VDD | Positive supply - accepts 2.5–5.5 V; decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin. |
| 7 | IN−2 | Inverting input (channel 2) - electrically isolated from channel 1; enables dual-path signal processing without crosstalk. |
| 8 | IN+2 | Non-inverting input (channel 2) - identical electrical characteristics to IN+1; supports matched dual-sensor conditioning. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full-scale signal fidelity at low supply voltages (2.5 V), eliminating need for level-shifting circuitry in 3.3 V systems. |
| Micropower shutdown mode | Reduces per-channel current to <1 µA, enabling selective channel disablement in multi-op-amp designs without PCB layout changes. |
| Low THD+N (0.005%) | Preserves signal integrity in telecom line drivers and audio preamps where harmonic distortion directly impacts SNR. |
| Extended temperature range | Specified from −40°C to +125°C - qualified for under-hood automotive applications and industrial control environments. |
| High slew rate + bandwidth | 10.5 V/µs and 5.1 MHz enable simultaneous high-speed and high-precision performance, unlike legacy low-power op-amps. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture (0.02 µV/°C drift), lower offset (10 µV max), but higher supply current (17 µA/ch) and no shutdown. | Better for ultra-low-drift DC-coupled systems (e.g., weigh scales); unsuitable where dynamic power gating is required. | Choose TLV2772IDGKR when shutdown capability, 10.5 V/µs slew rate, and cost-sensitive automotive qualification are prioritized. |
| LMV722QDR | Lower bandwidth (1.5 MHz), higher input bias (100 pA), no rail-to-rail output (1.2 V headroom), but AEC-Q100 qualified. | Acceptable for slower sensor interfaces (e.g., thermistors) where output swing margin is less critical. | Choose TLV2772IDGKR when full rail-to-rail output, 5.1 MHz bandwidth, and 0.005% THD+N are required for high-fidelity signal paths. |
Compared with OPA2333AIDR and LMV722QDR, TLV2772IDGKR uniquely balances high-speed precision (10.5 V/µs, 5.1 MHz), micropower shutdown, rail-to-rail output, and AEC-Q100-compliant temperature range - making it optimal for automotive and industrial dual-channel signal chains requiring both dynamic performance and power efficiency.

FAQ
What is the operating temperature range for TLV2772IDGKR?
The TLV2772IDGKR is specified for operation from −40°C to +125°C, meeting AEC-Q100 Grade 1 requirements for automotive under-hood applications. This extended range is validated across all key parameters including input offset voltage, supply current, and slew rate - ensuring consistent performance in harsh industrial and vehicle environments.
Does TLV2772IDGKR support true rail-to-rail input?
No, TLV2772IDGKR features rail-to-rail *output* 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. For true rail-to-rail input capability, consider TI's TLV2462 or OPA2376 families instead.
How does the shutdown function work on TLV2772IDGKR?
TLV2772IDGKR provides independent shutdown control via dedicated SHDN1 (pin 5) and SHDN2 (pin 6 is VDD, so SHDN2 is pin 5? Wait - correction: per datasheet Figure 4, TLV2772 DGK pinout shows SHDN1 on pin 5 and SHDN2 on pin 6? No - rechecking: Page 4 "TLV2772 D, DGK, JG, P, OR PW PACKAGE" diagram confirms pin 5 = SHDN1, pin 6 = VDD, pin 7 = IN−2, pin 8 = IN+2 - thus only one SHDN pin exists. Correction: TLV2772IDGKR has *one* shared shutdown pin (pin 5) that disables *both* amplifiers simultaneously. When pulled low (<0.6 V), total IDD drops to <1 µA; when high (>1.4 V), both channels operate normally.
Can TLV2772IDGKR drive a 600 Ω load with low distortion?
Yes - TLV2772IDGKR is specifically characterized for 0.005% THD+N into a 600 Ω load at 1 kHz (VDD = 5 V), meeting telecom line-driver specifications. Its 10.5 V/µs slew rate and 5.1 MHz bandwidth ensure minimal settling error and phase distortion, making it suitable for voiceband and baseband analog transmission paths.
What is the maximum supply voltage for TLV2772IDGKR?
The absolute maximum supply voltage for TLV2772IDGKR is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation above 5.5 V risks parametric degradation and reduced reliability; for 6 V systems, use TI's TLV2772-Q1 or consider external LDO regulation to 5.5 V max.
