MAX20336/MAX20337 DPST/SPDT Analog Switches Analog Devices MAX20336/MAX20337 Double-Pole Single Throw Analog Switches feature Beyond-the-Rails™ capability. This allows signals from -5.5V to +5.5V to pass without distortion, even when the power supply is below the signal range. Low on resistance (0.19Ω) makes the devices ideal for low-distortion switching applications, like audio or video. The MAX20336/MAX20337 operates from a single +1.6V to +5.5V power supply. A GPIO can provide VCCEN because of the low supply current requirement. The switches go to a high-impedance mode, and all analog signal ports can withstand signals from -5.5V to +5.5V when power is not applied.
