AD1838A
GENERAL DESCRIPTION
The AD1838A is a high performance single-chip codec featuring
three stereo DACs and one stereo ADC. Each DAC comprises a
high performance digital interpolation filter, a multibit -
modulator featuring Analog Devices’ patented technology,
and a continuous-time voltage out analog section. Each DAC
has independent volume control and clickless mute functions.
The ADC comprises two 24-bit conversion channels with
multibit - modulators and decimation filters.
The AD1838A also contains an on-chip reference with a nomi-
nal value of 2.25 V.
The AD1838A contains a flexible serial interface that allows
glueless connection to a variety of DSP chips, AES/EBU
receivers, and sample rate converters. The AD1838A can be
configured in left-justified, right-justified, I
2
S, or DSP com-
patible serial modes. Control of the AD1838A is achieved by
means of an SPI
compatible serial port. While the AD1838A
can be operated from a single 5 V supply, it also features a sepa-
rate supply pin for its digital interface that allows the device to
be interfaced to other devices using 3.3 V power supplies.
The AD1838A is available in a 52-lead MQFP package and is
specified for the industrial temperature range of –40oC to +85oC.
