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.

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.)
