2019年3月13日 · 刚发现一个tda7088+ta7642 am/fm收音机电路，am部分看起来象是超外差的。ta7642被用做中放。有大师分析一下吗。图中有几个元件的参数不明确，比如双联可变电容是amfm共用 ... tda7088+ta7642 am/fm超外差收音机电路图 ,矿石收音机论坛

Comparing the pinouts of the TDA7088T and CD9088CB, we can see that both ICs are in fact identical, and when I compared the working circuit diagrams, they too were identical with the same component values. The only difference was that the Chinese clone has documentation in Chinese and they have changed the names of the pins slightly.

The UTC TDA7088 is a bipolar integrated circuit for use in mono portable and pocket radios. It is used when a minimum of peripheral components (of small dimensions and low costs) is important. The circuit contains a frequency-lockedloop (FLL) system with an Intermediate Frequency (IF) of about 70kHz. Selectivity is achieved by active RC-filters.

Performance is the same as the TDA7000 IC in terms of sensitivity and sound quality. However, the TDA7088 has the mute permanently enabled so some weaker stations that could otherwise be received with a TDA7000 or TDA7010T cannot be received on the TDA7088T.
