APPLICATION INFORMATION
1998 Nov 03
9-bit analog-to-digital converter
for digital video
The analog and digital supplies should be separated and decoupled.
The external voltage regulator must be built such that a good supply voltage ripple rejection is achieved with respect to the LSB value. Eventually, the
reference ladder voltages can be derived from a well regulated V
(1) V
(2) Pins 15 and 16 may be connected to DGND in order to prevent noise influence.
RB
