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

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.
