MAX4570CAI+

The MAX4570CAI+ 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.

• Single supply range from 2.7V to 5.5V, dual ±2.7V to ±5.5V supply
• Operating temperature range from 0°C to 70°C
• Selectable soft switching mode for click less audio operation
• 43ohm typical on-resistance (±5V supplies), 4ohm typical on-resistance flatness
• 5ohm typical on-resistance matching between channels
• 0.014% total harmonic distortion with 1Kohm load
• Off-isolation is -110dB at 20KHz, -78dB at 4MHz, crosstalk is -95dB at 20KHz, -54dB at 4MHz
• Four auxiliary outputs that extend µP ports
