PRODUCT OVERVIEW
The AD1854 is a high performance, single-chip stereo, audio
DAC delivering 113 dB Dynamic Range and 112 dB 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 AD1854
is fully compatible with current DVD formats, including 96 kHz
sample frequency and 24 bits. It is also backwards compatible
by supporting 50
μ
s/15
μ
s digital de-emphasis intended for
“redbook” 44.1 kHz sample frequency playback from com-
pact discs.
The AD1854 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 AD1854 can be configured in left-justified, I
2
S, and right-
justified. The AD1854 accepts 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 AD1854
operates from a single 5 V power supply. It is fabricated 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.
