Fig.4 Line interface principle.

As can be seen from Fig.4, the internal circuitry is supplied

by pin V_BB, which is a strong supply point combined with

the line interface. The line current is flowing through the

R_SLPEresistor and is sunk by the V_BBvoltage stabilizer,

thus becoming available for a loudspeaker amplifier or any

peripheral IC. Its voltage is equal to 3.0 V for line currents

lower than 18 mA. It than increases linearly with the line

current and reaches the value of 5.3 V for line currents

greater than 45 mA. It is temperature compensated.

The reference voltage V_refcan be increased by connecting

an external resistor between pins REG and SLPE. For

large line currents, this increase can slightly affect some

dynamic performances such as maximum signal level on

the line for 2% THD. The voltage on pin V_BBis not affected

by this external resistor; see Fig.5 for the main DC

voltages.

The aim of the current switch TR1 and TR2 is to reduce

distortion of large AC line signals. Current I_SLPEis supplied

to V_BBvia TR1 when the voltage on SLPE is greater than

V_BB+ 0.25 V. When the voltage on SLPE is lower than this

value, the current I_SLPEis shunted to GND via TR2.
