Self Tuned Radio (STR)
TEA5757HL; TEA5759HL
AM CHARACTERISTICS
Input frequency fi = 1 MHz; m = 0.3; fm = 1 kHz; measured in test circuit at pin 11 (see Fig.11); S2 in position B;
Vi1 measured at input of matching network at pin 2; matching network adjusted to maximum output voltage at low input
level; Vi(n) refers to test circuit (see Fig.11); Vn refers to pin voltages; unless otherwise specied.
