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.PRODUCT HIGHLIGHTSTotal harmonic distortion is 100% tested.MSB trim feature allows superlinear operation.The AD1856 operates with ±5 V to ±12 V supplies.Serial interface is compatible with digital filter chips.1.5 µs settling time permits 2x, 4x and 8x oversampling.No external components are required.96 dB dynamic range.±3 V or ±1 mA output capability.16-bit resolution.2s complement serial input words.Low cost.16-pin plastic DIP or SOIC package.APPLICATIONSCompact disc playersDigital audio amplifiersDAT recorders and playersSynthesizers and keyboards
