Solid-state analog multiplexers and switches provide the ability to control and select a specified transmission path for an analog signal. In selecting analog multiplexers and switches attention must be paid to several key specifications which affect system performance, including ON Resistance (Ron) and Analog Input Leakage Current (Isoff).

SHAs/THAs are also popular in signal processing applications using ADCs with a subranging or successive approximation architecture. Significant improvement in dynamic performance can be made by placing fast SHAs with low aperture jitter ahead of flash ADCs. SHAs are also useful in applications including D/A deglitchers, simultaneous sampling systems, peak detectors, pulse stretchers, delay lines and data distribution systems.
