Product Details

The AD1856 is a monolithic 16-bit PCM Audio DAC. Each 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 Analog Devices’ BiMOS II process. The analog portion of the AD1856 is fabricated with bipolar and MOS devices as well as thin film resistors.
