THEORY OF OPERATION The AD5545/AD5555 contain a 16-/14-bit, current-output, digital-to-analog converter, a serial-input register, and a DAC register. Both parts require a minimum of a 3-wire serial data interface with an additional LDAC for dual channel simultaneous update. DIGITAL-TO-ANALOG CONVERTER ...
