Product specification
Speech and loudspeaker amplifier IC with
auxiliary inputs/outputs and analog multiplexer
TEA1097
Base microphone channel (pins TXIN, GATX, TXOUT
and GNDTX
) see Fig.7
The TEA1097 has an asymmetrical base microphone
input TXIN with an input resistance of 20 k
.
The DC biasing of the input is 0 V.
The output TXOUT is biased at two diodes voltage and has
a current capability equal to 20
μ
A (RMS). The gain of the
microphone amplifier (from pins TXIN to TXOUT) can be
adjusted from 0 to 31 dB to suit specific application
requirements.
The gain is proportional to the value of R
GATX
and equals
14.85 dB with R
GATX
= 30.1 k
. Without limitation from the
output, the microphone input stage can accommodate
signals up to 18 mV (RMS) at room temperature for 2% of
THD.
A capacitor can be connected in parallel with R
GATX
to
provide a 1st-order low-pass filter.
