TA2022AFN
1.5V AM / FM IF + MPX
TA2022AFN is the AM / FM IF + MPX system IC, which is developed for headphone radio in 1.5V use. This is included many functions and this can be used for digital tuning system with IF counter.
Features
· Suitable for combination with digital tuning system which is included IF counter.
· Built−in AM / FM IF count output for IF counter of digital tuning system. FM: 10.7MHz AM: 450kHz
· Adjustable for stop pulse sensitivity (in FM mode)
· For adopting ceramic discriminator, it is not necessary to adjust the FM QUAD detector circuit.
· Built−in AM IF output for AM stereo
· MPX input for main signal is independent of that for pilot signal. (MPX input for pilot signal is shared with AM input)
· MPX output is high−impedance in power off mode.
· Built−in power switch
· Low supply current (VCC = 1.2V, Ta = 25°C) FM mode: ICC2 = 5.5mA (typ.) AM mode: ICC3 = 3.7mA (typ.)
· Operating supply voltage range (Ta = 25°C) VCC (opr) = 0.95~2.2V
· Stereo operating supply voltage range (Ta = 25°C) VCC (opr) = 1.0~2.2V
Weight: 0.14 g (typ.)
