Differential analog switch


Posted on May 16, 2012    3315

The NPD5566 monolithic dual is used in a differential multiplex application where Rds(ON> should be closely matched) for the monolithic dual tracks at better than ±1% over wide temperature ranges (-25° C to +125° C), this makes it an unusual but ideal choice for an accurate multiplexer

This close tracking greatly reduces errors due to common-mode signals.
