LED control (pin LEDC)
The TEA1111A gives an on-hook/off-hook status
indication. This is achieved by a current made available at
pin LEDC to drive an external LED circuit connected
between pins SLPE and LN (see Fig.7). In the low voltage
area, which corresponds to low line current conditions, no
current is available for this LED. For line currents higher
than a threshold, the LEDC current increases
proportionally to the line current (with a ratio of 1:150). The
LEDC current is internally limited to 470
A (see Fig.8).
For 12 mA < Iline < 82 mA:
This LED circuit is referenced to SLPE. Consequently, all
the LED supply current will flow through the RSLPE resistor,
and does not affect the behaviour of the AGC.
Set impedance
In the audio frequency range, the dynamic impedance is
mainly determined by the RCC resistor. The equivalent
impedance of the circuit is illustrated in Fig.9.
