FUNCTIONAL DESCRIPTION
The TDA9861 consists of the following functions:
• source select switching block
• loudspeaker channel with effect controls
• headphone channel
• two port outputs for general purpose
• I2C−bus control
Source select switching block
The TDA9861 selects and switches the input signals from
three stereo or six mono sources as there are MAIN, AUX
and SCART (Fig.1) to one of the outputs SCART,
loudspeaker and headphone (crossbar-switching Table 3).
Due to the fact, that the main channel (LINE outputs) is
looped outside the circuit (from pins 9 and 24 to pins 10
and 23), signals can be used as LINE output or to insert a
‘surround sound decoder’.
Loudspeaker channel
Volume control is divided into the parts volume 1 and
volume 2 / balance. The first part (55 dB) controls left and
right channels simultaneously; the second part (23 dB)
controls volume and balance 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 (Fig.1) from −15 to +19 dB (2 dB steps).
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.
Headphone channel
The headphone channel is only equipped with volume /
balance control. A muting of 85 dB is provided.
2
I
C-bus control
All settings of control 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 all 3 stereo outputs are muted.
The muting can be switched off by writing a ‘0’ (non-muted)
into the mute control bits.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).

SOLDERING
Plastic dual in-line packages
Y DIP OR WAVE
B
The maximum permissible temperature of the solder is 260 °C; this temperature must not be in contact with the joint for
more than 5 s. The total contact time of successive solder waves must not exceed 5 s.
The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the
specified storage maximum. If the printed-circuit board has been preheated, forced cooling may be necessary
immediately after soldering to keep the temperature within the permissible limit.
EPAIRING SOLDERED JOINTS
R
Apply the soldering iron below the seating plane (or not more than 2 mm above it). If its temperature is below 300 °C it
must not be in contact for more than 10 s; if between 300 and 400 °C, for not more than 5 s.
