Overview
The AD7542KNZ is a precision 12-bit CMOS multiplying Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This device is designed for direct interface with 4- or 8-bit microprocessors, making it suitable for a variety of applications requiring high precision and low power consumption. The AD7542KNZ features a 12-bit DAC register, three 4-bit data registers, address decoding logic, and a 12-bit CMOS multiplying DAC. Data loading and transfer operations are similar to the WRITE cycle of a static RAM, and the device includes a clear input for easy reset to all zeros during power-up.
