Ultra-Small, Low-RON, Beyond-the-Rails DPDT Analog Switches

Industry's Smallest DPDT Can Switch ±5.5V Signals with a Single VCC as Low as 1.6V

Please check latest availability status for a specific part variant.


The MAX14689 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 +5.5V to pass without distortion, even when the power supply is below the signal range. The low on-resistance (0.25Ω) also makes the device ideal for low-distortion switching applications, such as audio or video.

The MAX14689 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 switch is controlled with a single control bit, CB.

The MAX14689 is available in a 1.2mm x 1.2mm, 0.4mm pitch, 9-bump wafer-level package (WLP) and 10-pin, 2.5mm x 2.0mm TDFN package. It operates over the -40°C to +85°C extended temperature range.
