Low voltage transmission circuits with
dialler interface
TEA1062; TEA1062A
Fig.15 Test circuit for defining TEA1062A voltage gain of MIC+, MIC
and DTMF inputs.
Voltage gain is defined as Gv =20log Vo/Vi.
For measuring gain from MIC+ and MIC
the MUTE input should be HIGH.
For measuring the DTMF input, the MUTE input should be LOW or open-circuit.
Inputs not being tested should be open-circuit.
