Product details
Overview
OPA2607IDGKR from Texas Instruments is a dual-channel, decompensated CMOS operational amplifier optimized for cost-sensitive, low-power, high-bandwidth applications. It delivers 50-MHz gain-bandwidth product, 3.8 nV/√Hz input voltage noise, rail-to-rail output swing within 8 mV of rails, and operates from 2.2 V to 5.5 V supply - enabling precision signal conditioning in portable current-sensing and ultrasonic transducer interfaces.
For engineers reviewing the OPA2607IDGKR datasheet, OPA2607IDGKR pinout, OPA2607IDGKR application, or OPA2607IDGKR equivalent, this device is selected for high-impedance sensor interfacing (e.g., piezoelectric transducers), battery-powered handheld test equipment, and PM2.5 particle sensor front-ends where low quiescent current (900 µA per channel) and stable ≥6 V/V gain configuration are critical.
Technical Context
The OPA2607IDGKR employs a decompensated CMOS architecture requiring minimum closed-loop gain of 6 V/V for stability, enabling its 50-MHz GBW while maintaining only 900 µA quiescent current per amplifier. Its high-impedance CMOS inputs (10 pA max bias current) and rail-to-rail output support single-supply operation down to 2.2 V with full dynamic range utilization into ADCs.
Each channel features independent power-down control (PD1/PD2 pins), reducing quiescent current to ≤1 µA per channel when disabled. The device is fully specified across –40°C to +125°C and supports robust performance in safety-critical industrial sensing - including light curtains and optical modules - with 1.5 µV/°C max input offset drift and 120 µV typical offset voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 50 MHz - enables stable high-gain (>6 V/V) signal amplification up to ~8 MHz small-signal bandwidth at G = 20 V/V. |
| Quiescent Current | 900 µA per channel - allows dual-amplifier operation on coin-cell or Li-ion battery for >1-year runtime in portable sensors. |
| Input Voltage Noise | 3.8 nV/√Hz - preserves SNR in low-level transducer signals (e.g., ultrasonic flow meters, sonar preamps). |
| Rail-to-Rail Output | Swings within 8 mV of supply rails - maximizes usable ADC input range in 3.3-V or lower systems. |
| Supply Range | 2.2 V to 5.5 V - supports direct interface with modern low-voltage MCUs and ADCs without level-shifting. |
| Input Offset Drift | 1.5 µV/°C max - ensures <1.2 µV total drift over 0–70°C ambient, critical for uncalibrated industrial temperature ranges. |
| Power-Down Current | ≤1 µA per channel - enables selective channel shutdown in multi-channel sensor arrays to extend system battery life. |
Pinout & Package
VSSOP-8 (DGK) package: 3.00 mm × 3.00 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected), RoHS-compliant, moisture sensitivity level 2a.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| IN1+ (Pin 3) | Noninverting input, Channel 1 | Direct connection point for high-Z sensors (e.g., photodiodes, piezoelectrics); common-mode range extends to VS−. |
| OUT1 (Pin 1) | Output, Channel 1 | Rail-to-rail capable (8 mV from rails); drives 10-kΩ loads with 24 V/µs slew rate and 1-µs 0.1% settling time. |
| VS− (Pin 4) | Negative supply / ground reference | Reference for single-supply operation; also serves as PD logic low threshold (0.2 × VS). |
| VS+ (Pin 8) | Positive supply | Accepts 2.2–5.5 V; powers both amplifiers and internal bias circuitry; sets PD logic-high threshold (0.7 × VS). |

Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-noise, rail-to-rail output op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2365AIDR | Unity-gain stable (vs OPA2607IDGKR's min 6 V/V), lower GBW (50 MHz vs 50 MHz), higher IQ (1.6 mA vs 0.9 mA), no power-down pins. | Better for variable-gain or unity-gain buffer stages; unsuitable for fixed high-gain stable designs requiring minimal current draw. | Select OPA2365AIDR only if gain flexibility or absence of power-down control is acceptable and board space permits larger SOIC-8. |
| LMV797MMX/NOPB | Lower GBW (88 MHz), higher noise (5.5 nV/√Hz), no power-down, wider supply (2.7–5.5 V), not specified beyond 85°C. | Suitable for non-automotive, room-temperature instrumentation; lacks extended temp rating and low-noise advantage for sensor front-ends. | Choose LMV797MMX/NOPB only for cost-driven, non-extended-temp applications where 5.5 nV/√Hz noise is tolerable and power-down is unnecessary. |
Compared with OPA2365AIDR and LMV797MMX/NOPB, the OPA2607IDGKR uniquely combines decompensated 50-MHz GBW, 3.8-nV/√Hz noise, dual independent power-down, and –40°C to +125°C qualification - making it optimal for battery-powered, high-reliability industrial sensing where gain stability, thermal robustness, and ultra-low standby current are mandatory.

FAQ
What is the minimum stable gain for OPA2607IDGKR?
The OPA2607IDGKR is decompensated and requires a minimum closed-loop gain of 6 V/V for stability. This architecture enables its 50-MHz gain-bandwidth product while maintaining low 900 µA quiescent current per channel. Attempting unity-gain or gains below 6 V/V may cause oscillation or phase margin degradation. Always verify stability with actual load and PCB parasitics using TI's TINA-TI simulation models for OPA2607IDGKR.
Does OPA2607IDGKR support true single-supply operation?
Yes, OPA2607IDGKR supports true single-supply operation from 2.2 V to 5.5 V. Its input common-mode voltage range extends to the negative rail (VS−), and its rail-to-rail output swings within 8 mV of both supply rails. This allows direct interface with microcontrollers and ADCs operating at 3.3 V or lower without level-shifting circuitry - a key enabler for compact, low-cost sensor nodes using OPA2607IDGKR.
How does the power-down feature work on OPA2607IDGKR?
OPA2607IDGKR provides two independent power-down pins: PD1 (pin 4 on X2QFN, not present on DGK) and PD2 (pin 6 on X2QFN). In the VSSOP-8 (DGK) package used for OPA2607IDGKR, power-down is not implemented - PD1 and PD2 pins are omitted. Therefore, OPA2607IDGKR operates continuously and does not support power-down mode. For power-down capability, select OPA2607IRUGR (X2QFN-10) instead.
What is the maximum capacitive load OPA2607IDGKR can drive stably?
OPA2607IDGKR can drive up to 100 pF capacitive load stably at G = 6 V/V with adequate phase margin (>45°), as verified in Figure 7-16 of the datasheet. For loads exceeding 100 pF, TI recommends adding an isolation resistor (RISO) between the output and load - values range from ~10 Ω (at 10 pF) to ~80 Ω (at 10 nF) depending on gain, per Figure 7-18. Always validate stability under actual board conditions using OPA2607IDGKR SPICE models.
Is OPA2607IDGKR suitable for transimpedance amplifier (TIA) applications?
Yes, OPA2607IDGKR is well-suited for TIA applications due to its 10 pA max input bias current, 3.8 nV/√Hz input voltage noise, and high 50-MHz GBW - all critical for preserving signal integrity in photodiode or piezoelectric sensor interfaces. Its CMOS input stage avoids leakage-induced errors, and rail-to-rail output maximizes dynamic range into downstream ADCs. Use with appropriate feedback capacitance (e.g., 2.5 pF per datasheet) to ensure stability in OPA2607IDGKR TIA configurations.
