DescriptionThe AD5545, 16-bit, current-output, digital-to-analog converter is designed to operate from a single +5 volt supply.
The applied external reference input voltage VREF determines the full-scale output-current. An internal feedback resistor (RFB) provides temperature tracking for the full-scale output when combined with an external I to V precision amplifier.
A serial-data interface offers high-speed, three-wire micro controller compatible inputs using serial-data-in (SDI), clock (CLK), and (CS). Additional LDAC function allows simultaneous update operation.
The AD5545/AD5555 are packaged in the low profile compact TSSOP-16 package.
