Universal hi-fi audio processor for TV TDA9859

FUNCTIONAL DESCRIPTION

The TDA9859 consists of the following functions:

• Source select switching block

• Loudspeaker channel with effect controls

• Two port outputs for general purpose

• I2C-bus control.

Source select switching block

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

−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

The TDA9859 selects and switches the input signals from
three stereo or six mono sources MAIN, AUX and SCART

pseudo-stereo effect’ are controlled by three bits. A muting
of 85 dB is provided.

(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 9 and 24 to
pins 10 and 23), so signals can be used as LINE output or
a surround sound decoder can be inserted.

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

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

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.

LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 134).
