NC
GND
CS
Not Connected.
Ground.
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 RDAC latch.
Active low preset to midscale; sets RDAC
registers to 80H.
Positive power supply, specified for
operation at both +3 V or +5 V. (Sum of
|V
DD
| + |V
SS
| <5.5 V.)
Active low input. Terminal A open-circuit.
Shutdown controls Variable Resistors #1
through #4.
Serial Data Input. MSB First.
Serial Clock Input, positive edge triggered.
Serial Data Output, Open Drain transistor
requires pull-up resistor.
Negative Power Supply, specified for
operation at both 0 V or –2.7 V. (Sum of
