Description
Maxim's MX7228 contains eight 8-bit voltage output digital-to-analog converters (DACs) with separate input latches and output buffers for simple microprocessor and TTL/CMOS interfacing. The MX7228 maintains 8-bit accuracy over the full operating temperature range without external trimming. Internally, data transfer into the data registers is via a common 8-bit TTL/CMOS compatible input bus. Logic inputs A2, A1, and A0 control which DAC is loaded after active-low WR goes low.

Key Features   Applications/Uses
  • Buffered Voltage Output
  • µP Compatible
  • TTL/CMOS Logic Compatible
  • Requires No External Adjustments
  • 24-Pin Narrow DIP Package
  • Operates from Single or Dual Supplies

 
  		• Arbitrary Function Generators
  		• Automatic Test Equipment
  		• Digital Offset/Gain Adjustment
  		• Industrial Process Control
  		• Minimum Component Count Analog Systems
