General Description
The UM4684 is a sub 1Ω (0.5Ω at 2.7V) dual SPDT analog switch designed for low voltage applications.
The UM4684 has on-resistance matching(less than 0.05Ω at 2.7V) and flatness (less than 0.2Ω at 2.7V) that are guaranteed over the entire voltage range. Additionally, low logic thresholds make the UM4684 an ideal interface to low voltage DSP control signals.
The UM4684 has fast switching speed with break-before-make guaranteed. In the ON condition, all switching elements conduct equally in both directions. OFF-isolation and crosstalk is -69dB at 100kHz.
