Stereo, Single Supply 16-, 18- And 20-Bit Sigma-Delta DACs

The AD1857 AD1858 have a simple but very flexible serial data input port that allows for glueless interconnection to a variety of ADCs DSP chips, AES/EBU receivers and sample rate converters. The AD1857 serial data input port CAN be configured in either 16-bit, 18-bit or 20-bit left-justified or I 2 S-justified modes. The AD1858 serial data input port CAN be configured in either 16-bit right-justified or DSP serial port compatible modes. The AD1857 AD1858 accept serial Audio data in MSB first, twos-complement format. A power-down mode is offered to minimize power consumption when the device is inactive. The AD1857 AD1858 operate from a single +5 V power supply. They are fabricated on a single monolithic integrated circuit and housed in 20-pin SSOP packages for operation over the temperature range 0C to +70C.
