1.5V AM/FM IF + MPX

TA2022AFNG 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.

特性 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
