The pin numbers in parenthesis refer to the TEA1083A/AT
LSE has to be HIGH to measure the voltage gain
PD has to be HIGH to measure in PD conditions
The pins not shown in the TEA1060 are left open-circuit
An impedance in series with pin SUP (e.g. an ammeter) should
be avoided as it interferes with the values of I
TR
and I
