The MAX4550/MAX4570 series serial-interface, programmable, dual 4x2 audio/video crosspoint switches are ideal for multimedia applications.
The MAX4550 and MAX4570 are serially controlled, dual 4x2 clickless audio/video analog crosspoint switches. Each device contains two identical switch arrays with four inputs and two outputs, selectable soft‑switching mode, and auxiliary outputs for controlling additional circuitry. They are offered in 28‑pin SSOP and wide‑SO packages and operate over a wide temperature range.
The datasheet details absolute maximum ratings, analog electrical characteristics for dual‑supply and single‑supply operation, interface I/O specifications (2‑wire I²C‑compatible for MAX4550, 3‑wire SPI/QSPI/MICROWIRE for MAX4570), typical operating characteristics, and package dimensions. Application examples include set‑top boxes, PC multimedia boards, high‑end audio systems, and video‑conferencing equipment.
