The ADC voltage reference and sampling clock input type can be selected using the CTRL pin. Even though there is an internal 100kΩ pull-up resistor to AVDD, the CTRL pin should be set to a voltage externally and not left floating. When using a voltage divider to set the CTRL pin voltage, resistor values less than 5kΩ should be used.
CTRL PIN VOLTAGE | VOLTAGE REFERENCE OPTION | CLOCKING TYPE |
---|---|---|
> 1.7V (Default) | External reference | Differential clock input |
0.5 - 0.7V | Internal reference | Differential clock input |
< 0.1V | Internal reference | Single-ended clock input |
