AD7542GKNZ

DAC 1CH R-2R 12Bit 16Pin PDIP Tube

Product Details

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.
