PIN 5/6:
MICROPHONEINPUTS
These are used for antilarsencontrol.
PIN 7 :
ANTILARSENFILTER 1
The second filter of the antilarsen system (1st filter
: pins 5-6)is formed by theRC networkR5C5.
In order to obtaina second order filter for the anti-
larsensystem, the cut-off frequencydefinedat this
pin, shouldbe the same as thatchosenfor the first
filter.
For correct TEA7532 operation R6 and R5 should
be fixed at 10 k
and1 k
respectively.
PIN 8 :
ANTILARSENFILTER 2
The gainandtheresponse oftheantilarsensystem
canbeadjustedrespectivelybytheresistor andthe
capacitoronthispin,accordingtotheacousticchar-
acteristics of the telephoneset.
The valueofthe resistorshouldnotexceed390k
.
When thevoltageon thispinexceedsthe threshold
voltageof 0.4 V, the AGC system is enabled.
PIN 9 :
EARPHONEINPUT
Input forloudspeakersignal.
PIN 10-12:
LOUDSPEAKEROUTPUTS
Maximum outputvoltage : V
pp
= 2 V
LS
- 2.5 V (with
a gainof 32 dB).
Maximum output current : dependingof the supply
current.
Twoloudspeakerconnectionmethodsarepossible,
using the amplifier in either ”H” mode or ”B” mode.
Note :
It is advisable to connect a 47 nF capacitor
in parallel with the loudspeaker (between
pins 10 and 12).
- ”H” Mode
Thisisforlow voltageworking,butat ahighersupply
current.The highestoutputpower is available inthis
mode,dueto the 5.5V maximum supplyvoltage re-
striction,imposed by the TEA7532.
Loudspeakerimpedancerecommendedvalue:50
.
Maximum gain available between earphone input
andloudspeakeroutput :32 dB.
