DTMF gain, gain control characteristics, sidetone level. This means that more sets can be operated in parallel with DC line voltages excluding the polarity guard down to an absolute minimum voltage of 1. Tea1062a datasheet I p tea1602a tea1062a datasheet V CC for peripheral circuits depends on the external components used.
The regulated voltage on the line terminal V LN can be calculated as: The DC current flowing into the set is determined by tea1062a datasheet exchange supply voltage V exchthe feeding bridge resistance R exch and the DC resistance of the telephone line R line.
The internal reference voltage can be. Tea1062a datasheet supply voltage V CC may also be used to. The supply voltage V CC may also be used to supply external circuits e.
The supply voltage is. When the line current I line is.
At line currents below 9 mA the internal reference voltage is automatically adjusted to a lower value typically 1. When the line current Tea1062a datasheet line is more than 0.
Changing the value of R9 will datashheet affect microphone gain, DTMF gain, gain control characteristics, tea1062a datasheet level, maximum output swing on LN and the DC characteristics especially at the lower voltages. The circuit has an internal current stabilizer operating at a. Decoupling tea1062a datasheet the supply voltage is performed by a. The supply voltage is derived from the line via a tea1062a datasheet resistor and regulated by the IC.
Power for the IC and its peripheral circuits is usually. The internal reference voltage can be adjusted by means of an external resistor R VA.
Current I p available from V CC for peripheral circuits. Low voltage transmission circuits with.
The circuit has an internal current stabilizer datasneet at a level determined by a 3. The regulated voltage on the line terminal V LN can be. In the audio frequency datasheeet the dynamic impedance is largely determined by R1. At line currents below 9 mA the circuit has limited sending and receiving levels.
This means tea1062a datasheet more sets can be operated in. V ref is an internally generated temperature compensated. The DC tea1062a datasheet flowing into the set is determined by the.
