A Terminal RDAC #2
Wiper RDAC #2, addr = 01
Analog Ground #4*
B Terminal RDAC #4
A Terminal RDAC #4
Wiper RDAC #4, addr = 11
Digital Ground*
Active Low Input. Terminal A open circuit.
Shutdown controls Variable Resistors #1
through #4.
Chip Select Input, Active Low. When CS
returns high data in the serial input register
is decoded based on the address bits and
loaded into the target DAC register.
Serial Data Input
Serial Data Output. Open drain transistor
requires pull-up resistor.
Serial Clock Input, positive edge triggered.
Active low reset to midscale; sets RDAC
registers to 20
Positive power supply, specified for opera-
tion at both +3 V and +5 V.
