PRODUCT DESCRIPTION

The AD1865 is a complete, dual 18-bit DAC offering excellent THD+N and SNR while requiring no external components. Two complete signal channels are included. This results in cophased voltage or current output signals and eliminates the need for output demultiplexing circuitry. The monolithic AD1865 chip includes CMOS logic elements, bipolar and MOS linear elements and laser-trimmed thin-film resistor elements, all fabricated on Analog Devices’ ABCMOS process.
