The MAX20327 ultra-small, low-on-resistance (RON) double-pole/double-throw (DPDT) analog switches feature Beyond-the-Rails™ capability that allows signals from -5.5V to +12V to pass without distortion, even when the power supply is below the signal range. The low on-resistance (0.2Ω) also makes the devices ideal for low-distortion switching applications, such as audio or video.
The MAX20327 is fully specified to operate from a single +1.6V to +5.5V power supply. Because of the low supply current requirement, VCC can be provided by a GPIO. When power is not applied, the switches go to a high-impedance mode and all analog signal ports can withstand signals from -5.5V to +5.5V. The switches are controlled with a single control bit, CB.
The MAX20327 is available in a 1.6mm x 1.6mm, 0.4mm pitch, 9-bump wafer-level package (WLP) and operates over the -40°C to +85°C extended temperature range.

Evaluation Kits (1)
The MAX20327 evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the functionality of the MAX20327 double-pole, double-throw (DPDT) analog switches in a 9-bump wafer-level package (WLP). The EV kits features enable evaluation of the analog switches through audio jack inputs and outputs, as well as SMA connectors for AC characteristic evaluation. Input power to the EV kits is provided by a Micro-USB, type-B connector or an external power supply.
