Features
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
accept any I
