FM/AM STEREO RADIORECEIVER
DESCRIPTION
ILA1238NS is a high performance one - chip bipolar ICS designed for FM/AM stereo radios. These include an FM/AM
front end, FM/AM IF amplifier, FM/AM detection output and FM stereo demodulator output. Bipolar silicon monolithic IC.
FEATURES
• Low current consumption
(In FM mode ID = 11.0 mA, in AM mode 8.5 mA,
VCC = 6.0V).
• Built - in LED drive circuit for tuning.
• Built - in LED drive circuit for stereo indicator.
• Built - in detune muting circuit for the FM band.
• Few external parts.
