AM/FM 1 CHIP RADIO

FUNCTION DESCRIPTION (PIN 16 DC VOLTAGE)

1. IF Gain Grouping Table

(1) Test Condition: V = 9V (Pin 13).

Pin 8 resistance (AM) = 47kW

Pin 16 resistance (FM) = 1.2kW

(2) Grouping Table

V16(AM)

V16(FM)

1.4 - 1.7 V

2.4 - 2.85V

2. IF gain is determined by DC voltage appeared at IC Pin 16.

The DC voltage at Pin 16 to the following values:

AM = 1.4 - 1.65V (DC)

FM = 1.9 - 2.10V (DC)

AM gain can be adjusted by the loading resistor value of Pin 8 (AM) from 33kW to infinity.

FM gain can be adjusted by the loading resistor value of Pin 16 (FM) from 3kW to 680.

Recommended resistance (Pin 8, Pin 16).

Pin 8 (AM) = 47kW

Pin 16 (FM) = 470kW
