PRODUCT DESCRIPTION
The AD1862 is a monolithic 20-bit digital audio DAC. Each device provides a 20-bit DAC, 20-bit serial-to-parallel input register and voltage reference. The digital portion of the AD1862 is fabricated with CMOS logic elements that are provided by Analog Devices’ BiMOS II process. The analog portion of the AD1862 is fabricated with bipolar and MOS devices as well as thin-film resistors.
New design, layout and packaging techniques all combine to produce extremely high performance audio playback. The design of the AD1862 incorporates a digital offset circuit which improves low-level distortion performance. Low stress packaging techniques are used to minimize stress-induced parametric shifts. Stress-sensitive circuit elements are located in die areas which are least affected by packaging stress. Laser-trimming of initial linearity error affords extremely low total harmonic distortion. Output glitch is also small, contributing to the over all high level of performance.
The noise performance of the AD1862 is excellent. When used with the recommended two external noise-reduction capacitors, it achieves 120 dB signal-to-noise ratio.
