LM3361A Low Voltage/Power Narrow Band FM IF System
General Description
The LM3361A contains a complete narrow band FM de-
modulation system operable to less than 2V supply voltage.
Blocks within the device include an oscillator, mixer, FM IF
limiting amplifier, FM demodulator, op amp, scan control,
and mute switch. The LM3361A is similar to the MC3361
with the following improvements: the LM3361A has higher
voltage swing both at the op amp and audio outputs. It also
has lower nominal drain current and a squelch circuit that
draws significantly less current than the MC3361. Device
pinout functions are identical with some slightly different op-
erating characteristics.
