TAS5028A
Similarly, the TAS5028A carries additional precision in the form of overflow bits to permit the value of
intermediate calculations to exceed the input precision without clipping. The TAS5028A advanced digital
audio processor achieves both of these important performance capabilities by using a high performance digital
audio processing architecture with a 48-bit data path, 28-bit filter coefficients, and a 76-bit accumulator.

Input Crossbar Mixer
The TAS5028A has a full 8x8 input crossbar mixer. This mixer permits each signal processing channel input
to be any ratio of any of the eight input channels. The control parameters for the input crossbar mixer are
programmable via the I
2
C interface. See Section 6.15,.

Bass and Treble Controls
From 32-kHz to 96-kHz data, the TAS5028A has four Bass and Treble tone controls. Each control has a
±
18-dB control range with selectable corner frequencies and 2nd order slopes. These controls operate four
channel groups:
L, R, and C (channels 1, 2, and 7)
LS, RS (channels 3 and 4)
LBS, RBS (or alternately called L and R lineout.) (channels 5 and 6)
Sub (channel 8)
For 176.4 kHz and 192 kHz data, the TAS5028A has two bass and treble tone controls. Each control has a
±
18-dB I
2
C control range with selectable corner frequencies and 2nd order slopes. These controls operate
two channel groups:
L and R
Sub
The bass and treble filters utilize a soft update rate that does not produce artifacts during adjustment.
