MAX4684EBC

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4684EBC is a dual single-pole double-throw (SPDT) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with low voltage supplies and features an on-resistance of 0.5 ohms or 0.8 ohms depending on the specific variant. The device is housed in a compact 12-WFBGA package, also referred to as UCSP or WLCSP. Key electrical parameters include a channel capacitance of 84pF and a maximum leakage current of 1nA. Crosstalk performance is rated at -68dB at 100kHz. Switching times are characterized by tON of 50ns and tOFF of 40ns at +3V, with a break-before-make action of 2ns. Digital logic inputs are compatible with 1.8V logic levels.
