Description
The MAX4851/MAX4851H/MAX4853/MAX4853H family of quad single-pole/single-throw (SPST) switches operates from a single +2V to +5.5V supply and can handle signals greater than the supply rail. These switches feature low 3.5 on-resistance with 40pF on-capacitance or 7 on-resistance with 30pF on-capacitance, making them ideal for switching audio and data signals. The MAX4851/MAX4851H are configured with four SPST switches and feature a comparator for headphone detection or mute/send key functions. The MAX4853/MAX4853H have four SPST switches but do not include a comparator. For over-rail applications, these devices offer either the pass-through or high-impedance option. For the
MAX4851/ MAX4853, signals greater than the positive supply (up to 5.5V) pass through the switch without distortion. For the MAX4851H/MAX4853H, the switch input becomes high impedance when the input signal exceeds the supply rail. The MAX4851/MAX4851H/MAX4853/MAX4853H are available in the space-saving, 16-pin, 3mm x 3mm thin QFN package and operate over the -40 to +85 extended temperature range.
