Most Robust Negative-Rail Audio Switch in a Tiny Footprint
The MAX14535E–MAX14539E are low on-resistance and high ESD-protected DPDT switches that multiplex analog signals, such as AC-coupled audio or video. These devices combine the low on-capacitance (CON) and low on-resistance (RON) necessary for high-performance switching applications in portable electronics, and include an internal negative supply to pass audio signals that swing below ground (down to -1.5V). The MAX14535E/MAX14537E/MAX14539E feature internal shunt resistors on the normally open path (and normally closed path, (MAX14539E)) to reduce clicks and pops heard at the output. The MAX14535E-MAX14539E have an enable input (EN) to reduce supply current and set all channels to high-impedance when driven low. When EN is driven low, the MAX14537E/MAX14538E have the lowest possible current consumption but cannot withstand negative rail signals. The MAX14535E/MAX14536E/MAX14539E can still withstand a negative signal to NC_, NO_, or COM_ from -1.5V to min(VCC, 3V). The MAX14535E-MAX14539E operate from a +2.4V to +5.5V supply. These devices can be powered from the typical analog supply voltage in a cell phone (+2.5V to +2.8V) or a lithium-ion (Li+) battery (about 4.3V max). The MAX14535E-MAX14539E have high ESD protection, up to ±15kV on COM_, and the NC_, NO_, and COM_ voltage can go up to 3.6V when VCC = 0V without damaging the devices. All devices are offered in a space-saving 10-pin, 1.4mm x 1.8mm UTQFN package, and operate over the -40°C to +85°C extended temperature range.
