Pin Descriptions
Potentiometers Pins
RWI (I = 0, 1, 2 OR 3)
RWi is the wiper terminal and is equivalent to the movable
terminal of a mechanical potentiometer. The position of the
wiper within the array is determined by the WRi register.
SHDN
The SHDN pin forces the resistor to end-to-end open circuit
condition and shorts all RWi to GND. When SHDN is
returned to logic high, the previous latch settings put RWi at
the same resistance setting prior to shutdown. This pin is
logically AND with SHDN bit in ACR register. I2C interface is
still available in shutdown mode and all registers are
accessible. This pin must remain HIGH for normal operation.
Bus Interface Pins
SERIAL DATA INPUT/OUTPUT (SDA)
The SDA is a bidirectional serial data input/output pin for I2C
interface. It receives device address, operation code, 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.
