Mnemonic
Description
1
AGND2
Analog Ground 2.
2
B2
Terminal B RDAC 2.
3
A2

B4
Terminal B RDAC 4.
7
A4
Terminal A RDAC 4.
8
W4
Wiper RDAC 4, Addr = 11
9
DGND
Digital Ground.
10
SHDN
Active Low Input. Terminal A open circuit. Shutdown controls Variable Resistor 1 through Variable Resistor 4.
11
CS
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.
12
SDI
Serial Data Input.
13
SDO
Serial Data Output. Open drain transistor requires a pull-up resistor.
14
CLK
Serial Clock Input, Positive Edge Triggered.
15
RS
Active Low Reset to Midscale. Sets RDAC registers to 80
16
V
Positive Power Supply. Specified for operation at both 3 V and 5 V.
