Active low input. Terminal A
open-circuit. Shutdown controls.
Variable Resistors of RDAC.
Serial Clock Input, positive edge
triggered.
Serial Data Input
Chip Select Input, Active Low.
When
CS
returns high, data will
be loaded into the RDAC register.
Active low preset to mid-scale; sets
RDAC registers to 80

.
Ground
Negative Power Supply, specified
for operation from 0 V to –5 V.
Logic Supply Voltage, needs to be
same voltage as the digital logic
controlling the AD5260.
No Connect (Users should not
connect anything other than dummy
pad on this pin)
Serial Data Output, Open Drain
transistor requires pull-up resistor.
