FUNCTIONAL DESCRIPTION
The TDA9859 consists of the following functions:
Source select switching block
The TDA9859 selects and switches the input signals from
three stereo or six mono sources MAIN, AUX and SCART
(see Fig.1) to the outputs SCART and loudspeaker
(crossbar-switching; Table 4). The main channel (LINE
outputs) is looped outside the circuit (from pins MOUT
and MOUT
used as LINE output or a surround sound decoder can be
inserted.
Effect controls
‘Linear stereo’, ‘stereo with spatial effect (30% or 52%
anti-phase crosstalk)’ and ‘forced mono with or without
pseudo-stereo effect’ are controlled by three bits. A muting
of 85 dB is provided.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134).
Notes
1. Equivalent to discharging a 200 pF capacitor through a 0
2. Equivalent to discharging a 100 pF capacitor through a 1.5 k series resistor (human body model).

Loudspeaker channel
Volume control is divided into volume control common and
volume control left/right. The common part
( 40 to +15 dB) controls the left and right channels
simultaneously; the left/right part ( 23 to 0 dB) controls the
volume of left and right channels independently. Treble
control provides a control range from 12 to +12 dB and
bass control from 12 to +15 dB. Extended bass control
can be provided by an external T-network (see Fig.1) from
I
All control settings are stored in subaddress registers.
Data transmission is simplified by auto-incrementing the
subaddresses. The on-chip Power-on reset sets the mute
bit to active, so both the SCART and the loudspeaker
outputs are muted.
The muting can be switched off by writing a ‘0’ (non-muted)
into the mute control bits.
