1-chip AM radio
Product specification
TEA5551T
Conditions: fo = 1 MHz; fm = 1 kHz; VS = 3 V; Rg = 50 Ω; m = 0.3 (unless otherwise specified).
Fig.4 Typical signal (S) and noise (N) output voltages, where Vo is the AF output voltage at pin 13, as a function
of the input voltage Vi. Vi is the input voltage at pin 16. Also shown is the total harmonic distortion (THD).
Conditions: VS = 3 V and 4.5 V; RL = 32 Ω; f = 1 kHz.
