The LM1815 is an adaptive sense amplifier and default gating circuit for motor control applications. It provides a one-shot pulse output whose leading edge coincides with the negative-going zero crossing of a ground referenced input signal such as from a variable reluctance magnetic pick-up coil.
The LMX243x devices are high performance frequency synthesizers with integrated dual modulus prescalers. The LMX243x devices are designed for use as RF and IF local oscillators for dual conversion radio transceivers.
