AD1866RZ

AD1866 is a complete dual 16bit DAC offering excellent performance while requiring a single +5V power supply. It is fabricated on Analog Devices’ ABCMOS wafer fabrication process. The monolithic chip includes CMOS logic elements, bipolar and MOS linear elements and laser trimmed, thin-film resistor elements. Careful design and layout techniques have resulted in low distortion, low noise, high channel separation and low power dissipation. The DACs on the AD1866 chip employ a partially segmented architecture. The first three MSBs of each DAC are segmented into 7 elements. The 13LSBs are produced using standard R-2R techniques. The segments and R-2R resistors are laser trimmed to provide extremely low total harmonic distortion. The AD1866 requires no deglitcher or trimming circuitry. Typical application includes multimedia workstations, PC audio add-in boards, portable CD and DAT players, automotive CD and DAT players and noise cancellation.
