Product Summary

The AD1865R-J is a complete, dual 18-bit DAC offering excellent THD+N and SNR while requiring no external components. Two complete signal channels of AD1865R-J are included. This results in cophased voltage or current output signals and eliminates the need for output demultiplexing circuitry. The monolithic AD1865R-J chip includes CMOS logic elements, bipolar and MOS linear elements and laser-trimmed thin-film resistor elements, all fabricated on Analog Devices’ ABCMOS process.
