Description
A Terminal
Wiper Terminal
B Terminal
Positive power supply, specified
for operation at both 5 V or 15 V.
(Sum of |V
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.

Description
Serial Data Output, Open Drain
transistor requires pull-up resistor.
A Terminal RDAC #1
Wiper RDAC #1, address A0 = 0
B Terminal RDAC #1
Positive power supply, specified for
operation at both 5 V or 15 V.
(Sum of |V
Active low input. Terminal A
open-circuit. Shutdown controls
Variable Resistors #1 through #2.
Serial Clock Input, positive edge
triggered.
Serial Data Input.
Chip Select Input, Active Low.
When CS returns high, data in
the serial input register is decoded,
based on the address Bit A
loaded into the target RDAC register.
Active low preset to mid-scale sets
RDAC registers to 80
Ground
Negative Power Supply, specified
for operation at both 0 V or –5 V
(Sum of |V
Logic Supply Voltage, needs to be
