OPA607IDCKR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA607IDCKR is a single-channel, low-power, rail-to-rail output CMOS operational amplifier from Texas Instruments. It features a gain-bandwidth product of 50 MHz and a slew rate of 24 V/µs. The device operates on a supply voltage range of 2.2 V to 5.5 V with a typical quiescent current of 900 µA per channel. Key electrical characteristics include a maximum input bias current of 10 pA, a typical offset voltage of 120 µV, and broadband noise of 3.8 nV/√Hz. It is housed in a compact SC-70 (DCK) package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Decompensated architecture optimized for stability at gains of 6 V/V or higher, enabling high bandwidth and low distortion.
• Rail-to-rail output capability maximizes dynamic range by swinging within millivolts of the supply rails.
• High-impedance CMOS inputs provide minimal loading on signal sources, ideal for interfacing with high-output impedance sensors.
• Integrated power-down mode reduces quiescent current to less than 1 µA when disabled.

Instrumentation, Op Amps, Buffer Amps Applications

• Current-sensing circuits
• Fish finders and sonar systems
• Ultrasonic flow meters
• Handheld test equipment
• Optical modules

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the specific application circuit maintains a closed-loop gain of at least 6 V/V to ensure stability, as this component utilizes a decompensated design. Confirm that the PCB layout accommodates the SC-70 package dimensions and adheres to thermal dissipation guidelines for the operating temperature range. Ensure the power supply voltage remains within the specified 2.2 V to 5.5 V limits during operation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a balance between cost, low power consumption, and moderate speed is required. It is suitable for applications needing rail-to-rail output swing and low noise without the complexity of bipolar amplifiers. Consider the minimum stable gain requirement of 6 V/V; if lower gains are necessary, alternative family members like the OPAx365 should be evaluated instead.

Instrumentation, Op Amps, Buffer Amps Part Context
