These switches feature low, well-controlled on resistance and wide analog signal range, making them ideal for precision analog signal switching. They are fabricated using Analog Devices' advanced linear compatible CMOS (LC2MOS) process, which offers benefits of low leakage currents, ultralow power dissipation and low capacitance for fast switching speeds with minimum charge injection. The on resistance profile is very flat over the full analog input range ensuring excellent linearity and low distortion when switching audio signals. Fast switching speed coupled with high signal bandwidth also make th...
