1. IF Gain Grouping Table
2. IF gain is determined by DC voltage appeared at IC Pin 16.
6
(1) Test Condition: V
(2) Grouping Table
The DC voltage at Pin 16 to the following values:
AM gain can be adjusted by the loading resistor value of Pin 8 (AM) from 33k
FM gain can be adjusted by the loading resistor value of Pin 16 (FM) from 3k
Recommended resistance (Pin 8, Pin 16).
V16(FM)
Pin 8 resistance (AM) = 47k
Pin 16 resistance (FM) = 1.2k
AM = 1.4
FM = 1.9
Pin 8 (AM) = 47k
Pin 16 (FM) = 470k
