Stereo, 96 kHz, Multibit ⌺⌬ DAC  
AD1855*  
PRODUCT OVERVIEW  
FEATURES  
The AD1855 is a high performance, single-chip stereo, audio  
DAC delivering 113 dB Dynamic Range and SNR (A-weighted—  
not muted) at 48 kHz sample rate. It is comprised of a multibit  
sigma-delta modulator with dither, continuous time analog  
filters and analog output drive circuitry. Other features include  
an on-chip stereo attenuator and mute, programmed through an  
SPI-compatible serial control port. The AD1855 is fully com-  
patible with current DVD formats, including 96 kHz sample  
frequency and 24 bits. It is also backwards compatible by sup-  
porting 50 µs/15 µs digital de-emphasis intended for “redbook”  
44.1 kHz sample frequency playback from compact discs.  
5 V Stereo Audio DAC System  
Accepts 16-/18-/20-/24-Bit Data  
Supports 24 Bits and 96 kHz Sample Rate  
Multibit Sigma-Delta Modulator with “Perfect Differen-  
tial Linearity Restoration” for Reduced Idle Tones  
and Noise Floor

Clock  
The AD1855 has a very 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 AD1855 can be configured in left-justified, I2S, right-  
justified, or DSP serial port compatible modes. The AD1855  
accepts 16-/18-/20-/24-bit serial audio data in MSB first, twos-  
complement format. A power-down mode is offered to mini-  
mize power consumption when the device is inactive. The  
AD1855 operates from a single +5 V power supply. It is fabri-  
cated on a single monolithic integrated circuit and housed in a  
28-lead SSOP package for operation over the temperature range  
0°C to +70°C.  
Switchable Clock Doubler
