... They feature high input impedance and open-col- lector outputs for maximum flexibility, enabling them to be used with a variety of oscillator topologies. Both the MAX2472 and MAX2473 operate from a single +2.7V to +5.5V supply. With V = +3.0V and -25dBm CC input power, the MAX2472 consumes 5.2mA, while the MAX2473 consumes only 2 ...
