The EVAL-ADA4620-1ARZ is an evaluation board designed for the ADA4620-1, a 36 V, precision, low noise, low offset drift, JFET op amp, available in an 8-lead SOIC package. The ADA4620-1 is preconfigured on this board as a unity-gain follower buffer. This four-layer evaluation board includes edge-mounted subminiature version A (SMA) connectors on both the inputs and output, facilitating efficient connections to the test and measurement equipment or external circuits.
The evaluation board's ground plane, component placement, and power supply decoupling are optimized for maximum circuit flexibility and performance. Additionally, the evaluation board features a variety of unpopulated resistor and capacitor pads, offering multiple choices and extensive flexibility for various application circuits and configurations, such as active loop filter, transimpedance amplifier (TIA), and charge amplifier. Furthermore, a combination of test points and edge-mounted SMA connectors are utilized for inputs, output, and signal measurements.
The evaluation board includes provisions for photodiode footprint, facilitating easy configuration of a TIA. Additionally, the evaluation board offers provisions for constructing various types of filters.
