Features

* ailable (EXTM). An appropriate DC blocking capacitor must be used to couple the modulating signal source to the EXTM pin. Also in this case, the VOTX output must be

Applications

* during the 22KHz transmission activated by DSQIN pin (or TEN I2C bit), the VOTX pin must be preventively set ON by the TTX I2C bit and, both the 13/18V power supply and the 22KHz tone, are provided by mean of VOTX output. As soon as the tone transmission is expired, the VOTX must be set to OFF by se
