TDA7000
A.C. CHARACTERISTICS
VP = 4,5 V; Tamb = 25 °C; measured in Fig.4 (mute switch open, enabled); frf = 96 MHz (tuned to max. signal
at 5 µV e.m.f.) modulated with ∆f = ± 22,5 kHz; fm = 1 kHz; EMF = 0,2 mV (e.m.f. voltage at a source impedance of
75 Ω); r.m.s. noise voltage measured unweighted (f = 300 Hz to 20 kHz); unless otherwise specified.
