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.
