Description
1
A
Resistor Terminal A.
2
W
Wiper Terminal W.
3
B
Resistor Terminal B.
4
VDD
Positive Power Supply. Specified for
operation from 5 V to 15 V (sum of |VDD|
+ |VSS| ≤ 15 V).
5
SHDN
Active Low, Asynchronous Connection
of Wiper W to Terminal B and Open
Circuit of Terminal A. RDAC register
contents unchanged. SHDN should tie
to VL if not used. Can also be used as a
programmable preset in power-up.
6
SCL
Serial Clock Input.
7
SDA
Serial Data Input/Output.
8
AD0
Programmable Address Bit 0 for
Multiple Package Decoding. Bit AD0
and Bit AD1 provide four possible
addresses.
9
AD1
Programmable Address Bit 1 for
Multiple Package Decoding. Bit AD0
and Bit AD1 provide four possible
addresses.
10
GND
Common Ground.
11
VSS
Negative Power Supply. Specified for
operation from 0 V to 5 V (sum of |VDD|
+ |VSS| ≤ 15 V).
12
O2
Logic Output Terminal O2.
13
VL
Logic Supply Voltage. Needs to be less
than or equal to VDD and at the same
voltage as the digital logic controlling
the AD5280.
14
O1
Logic Output Terminal O1.
