3.3V 10BIT ANALOGTODIGITAL CONVERTERS
WITH SERIAL CONTROL AND 11 ANALOG INPUTS
SLAS072E DECEMBER 1992 REVISED JANUARY 2004

NOTES: A. To minimize errors caused by noise at CS, the internal circuitry waits for a set up time plus two falling edges of the internal system
clock after CS
↓ before responding to control input signals. No attempt should be made to clock in an address until the minimum
chip CS setup time has elapsed.
B. The eleventh rising edge of the I/O CLOCK sequence must occur before the conversion is complete to prevent losing serial
interface synchronization.

NOTES: A. The eleventh rising edge of the I/O CLOCK sequence must occur before the conversion is complete to prevent losing serial
interface synchronization.
B. The I/O CLOCK sequence is exactly 16 clock pulses long.
