12-bit high-speed Analog-to-Digital
Converter (ADC)
The analog, digital and output supplies should be separated and decoupled.
(1) At power-up a high level clock must be provided within less than 1 s or a pull-up resistor must be connected between CLK and V
(2) R1, and R2 must be determined in order to obtain a voltage of 2.5 V on V
(3) V
V CCA
minimum current into these resistors must be about 1 mA.
