Description
The MAX4991–MAX4994 low on-resistance analog switches operate from a single +1.8V to +5.5V supply. The MAX4991/MAX4993 feature a slow turn-on time to reduce clicks and pops due to coupling capacitors and audio amplifiers with a DC output bias. This feature provides click-and-pop reduction without adding additional parts for existing architectures.
The MAX4991/MAX4992 are dual single-pole/double-throw (SPDT) switches, while the MAX4993/MAX4994 are double-pole/double-throw (DPDT) switches. The MAX4993/MAX4994 feature an active-low enable input (active-low EN) that sets all the channels to high impedance and reduces supply current when driven high. These devices have 0.3Ω on-resistance and 0.004% THD+N to route high fidelity audio signals.
The MAX4991–MAX4994 are available in space-saving 10-pin UTQFN (1.4mm x 1.8mm) package, and are specified for operation over the -40°C to +85°C extended temperature range.
