Product Specification
Speech and listening-in IC
TEA1096; TEA1096A
Fig.17 Dynamic limiter of the listening-in part.
Volume control: pin VCI (TEA1096A only)
The TEA1096A is provided with a volume control input
VCI, to adjust the gain of the loudspeaker channel by
means of a controlled DC voltage. A typical application is
illustrated in Fig.18. A pulse width modulation on a
microcontroller open drain output imposes a DC voltage
on the VCI capacitor:
