PIN 5-7:
LOUDSPEAKEROUTPUTS
Maximum outpt voltage: V

- 2.5V (with a
gain of 32dB).
Maximum output current: depending of the supply
current.
Figure14
Two loudspeaker connection methods are possi-
ble, using the amplifier in either symmetrical or
asymmetrical mode.
Note:
It is advisable to connect a 47nF capacitor in par-
allel with the loudspeaker(between pins 5 and7).
- ”Symmetrical”mode
This is for low voltage working, but at a higher
supply current. The highest output power is avail-
able in this mode, due to the 5.7Vmaximum sup-
ply voltage restriction, imposed by the TEA7530
Loudspeaker impedance recommended value:
50
.
Nominal gain available between earphone input
and loudspeakeroutputs: 32dB.
- ”Asymmetrical”Mode
This allows higher voltage operation, but at a
lower supply current.
Loudspeaker impedance recommended value:
25
.
Nominal gain available between earphone input
and loudspeakeroutput: 32 - 6 = 26dB.
Pin6:

: INTERNAL REFERENCE
Output which provides an internally regulated ref-
erencevoltage.
