TA2022AFN Overview
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA2022AFN 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.
TA2022AFN Key Features
- Suitable for bination 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
