Notes to figure 10
1. ISUP = IIN ITR
2. Gv = 20 log V---V--L--o-S---I
3.
ITR
=
-V----S---U----P-------S----R---E----F-
R 20
4. The pin numbers in parenthesis refer to the TEA1083A/AT
5. LSE has to be HIGH to measure the voltage gain
6. PD has to be HIGH to measure in PD conditions
7. The pins not shown in the TEA1060 are left open-circuit
8. An impedance in series with pin SUP (e.g. an ammeter) should
be avoided as it interferes with the values of ITR and ISUP.
