10-bit high-speed Analog-to-Digital
Converter (ADC)
The analog, digital and output supplies should be separated and decoupled.
(1) Single-ended clock signals can be applied if required.
(2) R1 and R2 must be determined in order to obtain a middle voltage of 3.6 V; see common mode input voltage.
(3) V
In addition, the minimum current into these resistors should be about 1 mA in order to ensure a sufficient analog input stability.
