The CXA1238 is a high-integrated AM, FM, stereo decoder single-chip radio IC produced by the Japanese Sony company. It is widely used in many kinds of audio radio systems such as car audio, home audio and so on. 1.Its functional features. The CXA1238 IC has internal: AM frequency conversion, AM mid-amplifier, wave detection, self-oscillation; FM high-amplifier, FM frequency conversion, FM mid-amplifier, frequency detection and stereo decoding circuit. Its auxiliary circuits have the tuning indication, stereo indication, squelch tuning and other functions. The CXA1238 IC's main features have the following points: Low current consumption. When the power voltage is 6V the AM static current is about 8.5mA and FM static current is about 11mA. Wide application range of the power voltage which means the circuit could work normally at the range of 2-10V. And so on.
