MAX2451 Datasheet (Maxim) - 3V / Ultra-Low-Power Quadrature Demodulator

MAX2451, 3V / Ultra-Low-Power Quadrature Demodulator

The monolithic MAX2451 is a quadrature demodulator with a supporting oscillator and divide-by-8 prescaler.

It operates from a single +3V supply and draws only 5.5mA.

The demodulator accepts an amplified and filtered IF signal in the 35MHz to 80MHz range, and demodulates it into I and Q baseband sign
