MAS9186
8 X 8-bit D to A Converter
• 3-pin Serial Data Interface
• Low Voltage Output Buffer
DESCRIPTION
MAS9186 is 8-channel 8-bit DAC, designed
primarily for trimmer replacement. Device is
controlled by a simple 3-line input. The output
buffers operate in the entire voltage range from
ground to the positive power supply rail.
FEATURES
• Eight 8-bit DACs on a single monolithic chip
• Voltage level output
• TSSOP 16 package
• Single +2.7V supply
• Power-on reset
BLOCK DIAGRAM
DAC is selected with three first bits in serial input
data (SDI-pin) and the DAC output value is set
according to the last 8 bits in serial input data.
APPLICATIONS
• High resolution monitors
• Automatic gain control
• Trimmer replacement
