Product Summary
The AD7543KRZ is a precision 12-bit monolithic CMOS multiplying DAC designed for serial interface applications. The DAC’s logic circuity consists of a 12-bit serial-in parallel-out shift register and a 12-bit DAC input register. Serial data at the AD7543KRZ 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 in-to register B under control of the LOAD inputs.
