General Description

The  MAX5214/MAX5216  are  pin-compatible,  14-bit and  16-bit  digital-to-analog  converters  (DACs).  The MAX5214/MAX5216 are single-channel, low-power, buffered voltage-output DACs. The devices use a precision external reference applied through the high resistance input  for  rail-to-rail  operation  and  low  system  power consumption.  The  MAX5214/MAX5216  accept  a  wide 2.7V  to  5.25V  supply  voltage  range.  Power  consumption  is  extremely  low  to  accommodate  most  low-power and  low-voltage  applications.
