MAX14689AETB+T

MAX14689AETB+T is an ultra-small, low-on-resistance (RON), double-pole/double-throw (DPDT) analogue switch. It features 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 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 analogue signal ports can withstand signals from -5.5V to +5.5V. The switch is controlled with a single control bit, CB. Applications include smartphones, tablets, portable audio/video equipment, low-distortion signal switches.
