Functional Pin Descriptions
Potentiometers Pins
RHI AND RLI
The high (RHi, i = 0, 1) and low (RLi, i = 0,1) terminals of the
ISL23325 are equivalent to the fixed terminals of a mechanical
potentiometer. RHi and RLi are referenced to the relative position
of the wiper and not the voltage potential on the terminals. With
WRi set to 255 decimal, the wiper will be closest to RHi, and with
the WR set to 0, the wiper is closest to RLi.
RWI
RWi (i = 0,1) is the wiper terminal, and it is equivalent to the
movable terminal of a mechanical potentiometer. The position of
the wiper within the array is determined by the WRi register.
VCC
Power terminal for the potentiometer section analog power
source. Can be any value needed to support voltage range of DCP
pins, from 1.7V to 5.5V, independent of the VLOGIC voltage.
Bus Interface Pins
SERIAL DATA INPUT/OUTPUT (SDA)
The SDA is a bi-directional serial data input/output pin for I2C
interface. It receives device address, wiper address and data
from an I2C external master device at the rising edge of the serial
clock SCL, and it shifts out data after each falling edge of the
serial clock.
SDA requires an external pull-up resistor, since it is an open drain
input/output.
