подскожите бедному учащемуся что обозначают вывода потенциометра analog device
1 AGND Analog Ground*
2 B2 Terminal B RDAC #2
3 A2 Terminal A RDAC #2
4 W2 Wiper RDAC #2, Addr = 012.
5 DGND Digital Ground*
6 SHDN Terminal A Open Circuit. Shutdown controls
Variable Resistors #1 and #2.
7 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.
8 SDI Serial Data Input
9 CLK Serial Clock Input, Positive Edge Triggered.
10 RS Active low reset to midscale; sets RDAC
registers to 80H.
11 VDD Positive power supply, specified for operation
at both 3 V and 5 V.
12 W1 Wiper RDAC #1, Addr = 002.
13 A1 Terminal A RDAC #1
14 B1 Terminal B RDAC #1
Analog Ground #2*
2 B2 Terminal B RDAC #2
3 A2 Terminal A RDAC #2
4 W2 Wiper RDAC #2, Addr = 012.
5 AGND4 Analog Ground #4*
6 B4 Terminal B RDAC #4
7 A4 Terminal A RDAC #4
8 W4 Wiper RDAC #4, Addr = 112.
9 DGND Digital Ground*
10 SHDN Active Low Input. Terminal A open circuit.
Shutdown controls Variable Resistors #1
through #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 pull-up resistor.
14 CLK Serial Clock Input, Positive Edge Triggered
15 RS Active Low reset to midscale; sets RDAC
registers to 80H.
16 VDD Positive power supply, specified for
operation at both 3 V and 5 V.
17 AGND3 Analog Ground #3*
18 W3 Wiper RDAC #3, Addr = 102
19 A3 Terminal A RDAC #3
20 B3 Terminal B RDAC #3
21 AGND1 Analog Ground #1*
22 W1 Wiper RDAC #1, Addr = 002
23 A1 Terminal A RDAC #1
24 B1 Terminal B RDAC #1

спасибо заранее
