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.

Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
