Ordering number : EN2012A
Functions
FM : IF amplifier, quadrature detector, AF preamplifier,
signal meter, tuning indicator drive output (common
with stop signal, muting drive output).
AM : RF amplifier, MIX, OSC (with ALC), IF amplifier,
detector, AGC, signal meter, tuning indicator drive
output (common with stop signal), IF signal output.
Features
• Minimum number of external parts required.
• Excellent S/N.
• Local OSC with ALC.
• Local OSC buffer.
• Tuning indicator pin (common with narrow-band stop
signal and muting drive output).
• Variable stop sensitivity (variable separately for FM,
AM)
• Low whistle.
• Signal meter pin.
• Espesially suited for AM stereo, IF count electronic
tuning because of AM IF signal output.
