GENERAL DESCRIPTION
The AD1856 is a monolithic, 16-bit pulse code modulation (PCM) audio DAC. The device provides a voltage output amplifier, 16-bit DAC, 16-bit serial-to-parallel input register, and voltage reference. The digital portion of the AD1856 is fabricated with CMOS logic elements that are provided by the Analog Devices, Inc., BiMOS II process. The analog portion of the AD1856 is fabricated with bipolar and MOS devices, as well as thin film resistors.
