DESCRIPTION
The X9430 is a monolithic CMOS IC that incorporates
two operational amplifiers and two nonvolatile digitally
controlled potentiometers. The amplifiers are CMOS
differential input voltage operational amplifiers with
near rail-to-rail outputs. All pins for the two amplifiers
are brought out of the package to allow combining
them with the potentiometers or using them as com-
plete stand-alone amplifiers.
The digitally controlled potentiometers consist of a
series string of 63 polycrystalline resistors that behave
as standard integrated circuit resistors. The SPI serial
port, common to both pots, allows the user to program
the connection of the wiper output to any of the resis-
tor nodes in the series string. The wiper position is
saved in the on board E2 memory to allow for nonvola-
tile restoration of the wiper position.
A wide variety of applications can be implemented
using the potentiometers and the amplifiers. A typical
application is to implement the amplifier as a wiper
buffer in circuits that use the potentiometer as a voltage
reference. The potentiometer can also be combined
with the amplifier yielding a digitally programmable gain
amplifier or programmable current source.
