PIN
NAME
FUNCTION
1
HA
Resistor A High Terminal. The voltage at HA can be higher or lower than the voltage at LA. Current
can flow into or out of HA.
2
WA
Resistor A Wiper Terminal
3
LA
Resistor A Low Terminal. The voltage at LA can be higher or lower than the voltage at HA. Current
can flow into or out of LA.
4
HB
Resistor B High Terminal. The voltage at HB can be higher or lower than the voltage at LB. Current
can flow into or out of HB.
5
WB
Resistor B Wiper Terminal
6
LB
Resistor B Low Terminal. The voltage at LB can be higher or lower than the voltage at HB. Current
can flow into or out of LB.
7
BYP
Internal Power-Supply Bypass. For additional charge-pump filtering, bypass to GND with a capaci-
tor close to the device.
8
I.C.
Internally Connected. Connect to GND.
9
GND
Ground
10
A2
Address Input 2. Connect to V_DD or GND.
11
A1
Address Input 1. Connect to VDD or GND.
12
A0
Address Input 0. Connect to VDD or GND.
13
SDA
I²C-Compatible Serial-Data Input/Output. A pullup resistor is required.
14
SCL
I²C-Compatible Serial-Clock Input. A pullup resistor is required.
15
N.C.
No Connection. Not internally connected.
16
VDD
Power-Supply Input. Bypass VDD to GND with a 0.1FF capacitor close to the device.
