Richardson RFPD Converter - DAC AD7543JNZ

The AD7543 is a precision 12-bit monolithic CMOS multiplying DAC designed for serial interface applications.The DAC's logic circuitry consists of a 12-bit serial-in parallelout shift register (Register A) and a 12-bit DAC input register (Register B). Serial data at the AD7543 SRI pin is clocked into Register A on the leading or trailing edge (user selected) of the strobe input. Once Register A is full its contents are loaded into Register B under control of the LOAD inputs.
