Description
The TDA7535 is a stereo, digital-to-analog
converter designed for audio application,
including digital interpolation filter, a third order
multi-bit Delta-Sigma DAC, a third order
Chebyshev's reconstruction filter and a differential
to single ended output converter. This device is
fabricated in highly advanced CMOS, where high
speed precision analog circuits are combined with
high density logic circuits. The TDA7535,
according to standard audio converters, can
2
accept any I
S data format.

February 2009
Delta/sigma cascade 20 bit stereo DAC
The TDA7535 is available in SO14 package. The
total power consumption is less than 75 mW.
TDA7535 is suitable for a wide variety of
applications where high performance are
required. Its low cost and single 3.3 V power
supply make it ideal for several applications, such
as CD players, MPEG audio, MIDI applications,
CD-ROM drives, CD-Interactive, digital radio
applications and so on. An evaluation board is
available to perform measurement and to make
listening tests.
