Maxim MAX11664 Low-Power 10-Bit ADC
The MAX11664 ADC integrated into the peripheral shield provides high-resolution analog-to-digital conversion, making it ideal for applications requiring precise signal processing. With its 10-bit resolution and sampling rate of up to 500ksps, the MAX11664 ensures accurate and efficient conversion of analog signals into digital data for FPGA-based applications.
The ADC features dual single-ended analog inputs connected via SMA ports, as well as a potentiometer joystick for generating analog signals. Users can select the input source using a jumper-based configuration mechanism. The 3x2 jumper header on the shield determines the ADC input channel and source according to the table:
| Joystick Input | ADC Input CH1 | SMA Input ADC 1 |
| Joystick Input | ADC Input CH2 | SMA Input ADC 2 |
| Peripheral | DE10-Lite Port |
|---|---|
| SCLK | PIN_AA7 |
| ADC_CS | PIN_AA8 |
| ADC_CHSEL | PIN_AA9 |
| ADC_DOUT | PIN_AB10 |
