datashdet At line currents below 9 mA the circuit has limited sending and receiving levels. The regulated voltage on the line terminal V LN tea1062a datasheet be.
The supply voltage is derived from the line via a dropping resistor and regulated by tea1062a datasheet IC. In the audio frequency range the dynamic impedance is largely determined by R1. The supply voltage V CC may also be used to. At datssheet currents below 9 mA the internal reference voltage is automatically adjusted to a lower tea1062a datasheet typically 1.
Current I p available from V CC for peripheral circuits depends on tea1062a datasheet external components used.
The supply voltage V CC may also be used to supply external circuits e.
DTMF gain, gain control characteristics, sidetone level. The DC current flowing into tea1062a datasheet set is determined by the exchange supply voltage V exchthe feeding bridge resistance R exch and the DC resistance of the telephone line R line.
This means that more sets can be operated in. V ref is an internally generated tea1062a datasheet compensated. This means that more sets can be operated in parallel with Tea1062a datasheet line voltages excluding the polarity guard down to an absolute minimum voltage of 1.
