Fast, Low-Voltage, Dual 4Ω SPDT CMOS Analog Switches

The MAX4635/MAX4636 are fast, dual 4Ω single-pole/double-throw (SPDT) analog switches that operate with supply voltages from +1.8V to +5.5V. High switching speeds, 1Ω on-resistance flatness, and low power consumption make these devices ideal for audio/video, communications, and battery-operated devices. Containing two independently controllable SPDT switches in 10-pin µMAX® and 10-pin 3mm x 3mm thin QFN packages, the MAX4635/MAX4636 use little board space, and have low power consumption ensuring minimal impact on your power budget. The analog signal range extends to the supply rails. The MAX4635 has inverted logic compared to the MAX4636.
