Description
Output of the second hybrid amplifier.
Chip Disable. A logic low (<0.8V) sets normal operation.
Filter input.
Filter output.
Mute input. A logic “1” sets normal speech mode.
A resistor connected from this pin to VSS sets the AC terminating impedance.
Power supply for the speech network. Supply voltage is derived from loop current.
TX amp output operates on this pin.
Resistor at this pin set the DC characteristics of the circuit.
A 1.7 volt regulated output which can be used to bias the mic.
Inverting differential input to the mic amp.
Non-inverting differential input to the mic amp.
Ground pin for the speech network.
Mic amp output.
Input to the TX amp from the Mic amp.
Loop current sensing input.
