S1A0427B01 AM/FM 1 CHIP RADIO

(PIN 16 DC VOLTAGE) 1. IF Gain Grouping Table (1) Test Condition: VCC = 9V (Pin 13). Pin 8 resistance (AM) = 47kΩ Pin 16 resistance (FM) = 1.2kΩ (2) Grouping Table V16(AM) V16(FM) 2.4 − 2.85V 1.4 - 1.7 V 2B 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 .
