PIN CONFIGURATION
PIN NAMES
PRINCIPLES OF OPERATION
The X9430 is an integrated microcircuit incorporating two
digitally controlled potentiometers, two operational
amplifiers and their associated registers and counters;
and the serial interface logic providing direct communica-
tion between the host and the digitally controlled
potentiometers.
Serial Interface
The X9430 supports the SPI interface hardware con-
ventions. The device is accessed via the SI input with
data clocked in on the rising edge of SCK. CS must be
LOW and the HOLD and WP pins must be HIGH dur-
ing the entire operation.
