ADI AD7542KPZ

The AD7542 is a precision 12-bit CMOS multiplying DAC designed for direct interface to 4- or 8-bit microprocessors. The functional diagram shows the AD7542 to consist of three 4-bit data registers, a 12-bit DAC register, address decoding logic and a 12-bit CMOS multiplying DAC. Data is loaded into the data registers in three 4-bit bytes, and subsequently transferred to the 12-bit DAC register. All data loading or data transfer operations are identical to the WRITE cycle of a static RAM. A clear input allows the DAC register to be easily reset to all zeros when powering up the device. The AD7542 is manufactured using an advanced thin-film on monolithic CMOS fabrication process. Multiplying capability, low power dissipation, +5V operation, small size (16-pin DIP and 20 terminal surface mount packages) and easy μP interface make the AD7542 ideal for many instrumentation and industrial control applications.
