MAX4570CAI+ (MAXIM INTEGRATED PRODUCTS)

The MAX4570CAI+ from Maxim Integrated Products is a serially controlled, dual 4x2, click less audio/video analogue cross point switch in 28 pin SSOP package. Device contains two identical cross point switch arrays, each with four inputs and two outputs. To improve off-isolation use the additional cross point inputs SA and SB as shunts. Each output is selectively programmable for click less or regular mode operation. A set of internal resistive voltage dividers supplies DC bias for each output when using AC coupled inputs. The MAX4570 uses a 3-wire SPI™/QSPI™ or MICROWIRE™ compatible serial interface. Ideally used at set-top boxes, PC multimedia boards, high end audio systems and video conferencing systems.
