SMBus to Analog Interface
TM
DESCRIPTION
The LX1800 bridges the analog and
digital world. The analog interface
contains and eight bit ADC and 8 bit
DAC and the digital interface is a
serial data SMBus interface. The
LX1800 works well in a feedback
control system such as an LCD
backlight system where the analog
output of an ambient light sensor such
as the LX1972 can be digitized
allowing the micro controller to adjust
the
analog
dimming
signal
accordingly.
The LX1800 has an internal bandgap
reference and also allows the use of an
external
reference.
The
external
reference can be used as an analog input
for volume control using the DAC or to
provide wider range for high amplitude
analog signals.
The 8 pin MLP package is small
occupying no more area than a TSOT
package.
