The AD7543JNZ is a precision 12-bit monolithic CMOS multiplying Digital-to-analog Converter (DAC) designed for serial interface applications. The DAC logic circuitry consists of a 12-bit serial-in parallel out shift register and a 12-bit DAC input register. Serial data at the AD7543 SRI pin is clocked into register-A on the leading or trailing edge of the strobe input. Once register-A is full its contents are loaded into register-B under control of the LOAD inputs. Initialization is simplified by the use of the CLR input which provides an asynchronous reset of register-B.
Serial load on positive or negative strobe
Asynchronous CLEAR input for initialization
Full 4-quadrant multiplication
Low multiplying feedthrough - 1LSB maximum at 10kHz
