com LX1800 TM ® SMBus to Analog Interface P RODUCTION D ATA S HEET DESCRIPTION KEY FEATURES ƒ 8 bit accuracy ƒ ADC and DAC in one package ƒ Fully compliant to standard SMBus ƒ Bus controllable Sleep mode ƒ Optional external reference 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.
