PRODUCT OVERVIEW  
The AD1852 is a complete high performance single-chip stereo  
digital audio playback system. It is comprised of a multibit sigma-  
delta modulator, digital interpolation 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 AD1852 is fully compatible with all known DVD  
formats including 192 kHz as well as 96 kHz sample frequen-  
cies and 24 bits. It also is backwards compatible by supporting  
50 µs/15 µs digital de-emphasis intended for “Redbook” compact  
discs, as well as de-emphasis at 32 kHz and 48 kHz sample rate.  
The AD1852 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  
AD1852 can be configured in left-justified, I2S, right-justified,  
or DSP serial port compatible modes. It can support 16, 18, 20,  
and 24 bits in all modes. The AD1852 accepts serial audio data  
in MSB first, twos-complement format. The AD1852 oper-  
ates from a single 5 V power supply. It is fabricated on a single  
monolithic integrated circuit and is housed in a 28-lead SSOP  
package for operation over the temperature range 0°C to 70°C.  
–105 dB THD+N (Mono Application Circuit)
