TDA7361 数据手册 ( 数据表 ) - STMicroelectronics

DESCRIPTION
The TDA7361 is a low-power narrow band FM IF demodulation system operable to less than 2 V supply voltage.
The device includes Oscillator, Mixer, Limiting Am plifier, Quadrature Discriminator, Op. Amp. Squelch, Scan Control and Mute Switch. The TDA7361 is designed for use in NBFM dual  conversion communication equipments using a 455 KHz ceramic filter like cordless telephones, walkie-talkies, scan receivers, etc.
