Product details
Overview
OPA607IDCKR from Texas Instruments is a single-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 supply rails, and operates from 2.2 V to 5.5 V - enabling precision signal conditioning in portable current-sensing and ultrasonic transducer interfaces.
For engineers reviewing the OPA607IDCKR datasheet, OPA607IDCKR pinout, OPA607IDCKR application, or OPA607IDCKR equivalent, key selection criteria include minimum stable gain (≥6 V/V), power-down mode (<1 µA quiescent current), input offset drift (≤1.5 µV/°C), and SC70-6 package compatibility with space-constrained PCB layouts.
Technical Context
The OPA607IDCKR uses a decompensated CMOS architecture requiring minimum closed-loop gain of 6 V/V for stability, enabling high GBW (50 MHz) with low quiescent current (900 µA). Its high-impedance CMOS inputs (≤10 pA bias current) and rail-to-rail output support direct interfacing with high-Z sensors like piezoelectric transducers and photodiodes.
Integrated power-down functionality (PD pin) reduces quiescent current to ≤1 µA, while maintaining fast turn-on/turn-off times (15 µs / 0.5 µs). The device is fully specified from –40°C to +125°C and supports single-supply operation down to 2.2 V, making it suitable for battery-powered industrial and safety-critical sensing systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA365AIDBVR | Unity-gain stable (vs OPA607IDCKR's min 6 V/V), 50-MHz GBW, 4.5 nV/√Hz noise, 1.6-mA IQ | Better for unity-gain buffers and low-impedance source driving; higher power disqualifies ultra-low-power use cases | Select OPA365AIDBVR when gain <6 V/V is required or when lower input capacitance (1.2 pF) is critical for stability |
| OPA837IDBVR | Bipolar input (vs CMOS), 50-MHz GBW, 4.7 nV/√Hz, 0.6-mA IQ, unity-gain stable, 105 V/µs slew rate | Superior speed and drive strength but higher input bias current (100 nA) limits high-Z sensor use | Select OPA837IDBVR for high-speed, low-distortion applications with resistive sources (e.g., DAC outputs), not piezoelectric sensors |
Compared with OPA365AIDBVR and OPA837IDBVR, the OPA607IDCKR uniquely balances low-noise CMOS input, rail-to-rail output, and sub-1-mA quiescent current - making it the only choice among the three for battery-powered, high-impedance sensor front-ends requiring ≥6 V/V gain.

FAQ
What is the minimum stable gain for OPA607IDCKR?
The OPA607IDCKR is decompensated and requires a minimum closed-loop gain of 6 V/V for stability. This design enables its 50-MHz gain-bandwidth product while maintaining low quiescent current. Attempting unity-gain or gains below 6 V/V may cause oscillation or degraded phase margin. Always verify stability with load and layout parasitics using TI's TINA-TI simulation models for OPA607IDCKR.
Does OPA607IDCKR support true single-supply operation?
Yes, OPA607IDCKR supports true single-supply operation from 2.2 V to 5.5 V. Its input common-mode range extends to the negative rail (VS−), and its rail-to-rail output swings within 8 mV of both supply rails. This allows direct interfacing with sensors referenced to ground in 3.3-V or lower systems - a key enabler for OPA607IDCKR use in portable PM2.5 sensors and garden tool controllers.
How does the power-down feature work on OPA607IDCKR?
The PD pin on OPA607IDCKR is active-low: connecting it to VS− disables the amplifier and reduces quiescent current to ≤1 µA; leaving it floating or connecting to VS+ enables normal operation (900 µA typ). No external pull-up is required. Turn-on delay is ≤15 µs, and turn-off delay is ≤0.5 µs - making OPA607IDCKR suitable for microcontroller-gated operation in battery-powered sonar burst modes.
What is the input offset voltage drift specification for OPA607IDCKR?
The OPA607IDCKR has a maximum input offset voltage drift of ±1.5 µV/°C over the full –40°C to +125°C operating range. This tight drift spec ensures predictable, low-drift performance in automotive and industrial environments - critical for OPA607IDCKR deployment in current-sensing circuits where thermal gradients affect shunt measurement accuracy without recalibration.
Which package does OPA607IDCKR use, and what are its board-level implications?
OPA607IDCKR uses the SC70-6 (DCK) package: 2.00 mm × 1.25 mm, 0.65-mm pitch. Its small footprint saves PCB area in dense layouts (e.g., optical modules), while its thermal resistance (RθJA = 219.7°C/W) demands careful attention to copper pour and thermal vias. The exposed pad variant is not offered - so OPA607IDCKR relies on trace conduction and ambient convection for thermal management in continuous high-output-current operation.
