Analog Devices / Maxim Integrated 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. 

Analog Devices MAX20336/MAX20337 Double-Pole Single Throw Analog Switches are available in a 1.308mm x 0.828mm, 0.4mm pitch, 6-bump wafer-level package (WLP) and 1.25mm x 1.75mm 6-pin FC2QFN package, and operate over the -40°C to +85°C extended temperature range.
