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 OR’d with SHDN bit in ACR register. I
2
C interface is
still available in shutdown mode and all registers are
accessible. This pin must remain HIGH for normal operation.
