Product specification
Multistandard dual carrier stereo sound decoder
TDA9873H
Power supply
The different supply voltages and currents required for the
analog and digital circuits are derived from two internal
band gap reference circuits. One of the band gap circuits
internally generates a voltage of approximately 2.4 V,
independent of the supply voltage and temperature.
A voltage regulator circuit, connected to this voltage,
produces a constant voltage of 3.55 V which is used as an
internalreferencevoltage.TheAF referencevoltageV

internal resistor at pin 6. No additional DC load for

is allowed.
Analog ground (AGND, pin 7) and digital ground
(DGND, pin 27) should be connected directly to the IC.
Pin 13 is internal analog ground.
Power
-
on reset
When a Power-on reset is activated by switching on the
supply voltage or because of a supply voltage breakdown,
the 117/274 Hz DPLL, 117/274 Hz integrator and the
registers will be reset. Both AF channels (main and mono)
are muted. The ports are in position HIGH. Gain stereo
adjustment is 0 dB. Auto mute is active. For detailed
information see Table 12.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134).
