AD9238 chip manual.

Part 2.1: Single-ended Input and Operational Amplifier

Circuit

The single-ended input AD1 and AD2 are input through two SMA headers,

J5 or J6, and the voltage of the single-ended input is -5V~+5V.

On the FPGA development board, the input voltage of -5V~+5V is reduced

to -1V~+1V through the AD8065 chip and voltage divider resistors. If the user

wants to input a wider range of voltage, just modify the resistance of the

front-end voltage divider resistor.

Conversion Formula: V

5/17

= (1.0/5.02)*V
