Features and Benefits
- Full featured evaluation board for the ADA4625-2
- Enables quick prototyping
- User defined circuit configuration
- Edge mounted SMA connector provisions
- Easy connection to test equipment and other circuits
The evaluation board for the ADA4625-2 is a low noise, fast settling, single-supply, rail-to-rail output (RRO), junction field effect transistor (JFET) op amp in an 8-lead small outline integrated circuit (SOIC) package with an exposed pad.
The design of this evaluation board emphasizes simplicity and ease of use. This evaluation board is a two layer board that accommodates edge mounted Subminiature Version A (SMA) connectors on the inputs and outputs. The SMA connectors provide efficient connection to test equipment or other circuitry.
The evaluation board ground plane, component placement, and power supply bypassing are optimized for maximum circuit flexibility and performance. The exposed pad of the ADA4625-2 is connected to the ground plane on the evaluation board to enhance thermal and noise performance. The evaluation board uses a combination of surface mount technology (SMT) component case size 0603, with the exception of the C2 and C6 bypass capacitors, which have a maximum standard size of 1206. The evaluation board features a variety of unpopulated resistor and capacitor pads that provide the user with multiple choices and extensive flexibility for different application circuits and configurations, such as active loop filters, transimpedance amplifiers (TIAs), and charge amplifiers.
Consult the ADA4625-2 data sheet for full details. The data sheet must be used in conjunction with this user guide when using the evaluation board.
