LM3661A Product details

Description

The LM3361A contains a complete narrow band FM demodulation 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 Devic

Features

Y Functions at low supply voltage (less than 2V) Y Highly sensitive (b3 dB limiting at 2 0 mV input typical) Y High audio output (increased 6 dB over MC3361) Y Low drain current (2 8 mA typ VCCe3 6V) Y Minimal drain current increase when squelched Y Low external pa.
