DESCRIPTION
The TDA7535 is a stereo, digital-to-analog converter
designed for audio application, including digital inter-
polation filter, a third order multibit Delta-Sigma DAC,
a third order Chebyshev's reconstruction filter and a
differential to single ended output converter. This de-
vice is fabricated in highly advanced CMOS, where
high speed precision analog circuits are combined
with high density logic circuits. The TDA7535, ac-
cording to standard audio converters, can accept any
I²S data format.

ORDERING NUMBER: TDA7535
The TDA7535 is available in SO-14 and TSSOP-14
packages. The total power consumption is less than
75mW.
TDA7535 is suitable for a wide variety of applications
where high performance are required. Its low cost
and single 3.3V power supply make it ideal for sever-
al 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.
