PRODUCT OVERVIEW
The AD1837 is a high performance single-chip codec featuring
four 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 AD1837 also contains an on-chip reference with a nominal
value of 2.25 V.
The AD1837 contains a flexible serial interface that allows for
glueless connection to a variety of DSP chips, AES/EBU receiv-
ers, and sample rate converters. The AD1837 can be configured
in left-justified, right-justified, I
2
S, or DSP compatible serial
modes. Control of the AD1837 is achieved by means of an SPI
compatible serial port. While the AD1837 can be operated from
a single 5 V supply, it also features a separate supply pin for its
digital interface that allows the device to be interfaced to other
devices using 3.3 V power supplies.
The AD1837 is available in a 52-lead MQFP package and is
specified for the industrial temperature range of –40oC to +85oC.
