The MAX498CWI+ by Analog Devices / Maxim Integrated is a high-speed, quad/triple, single-pole/double-throw (SPDT) video switch featuring integrated closed-loop buffer amplifiers. These amplifiers provide a +6dB gain, 250MHz -3dB bandwidth, and a 1250V/µs slew rate, making the device suitable for a wide range of video applications.
Key electrical characteristics include a fast 3ns channel switching time, 12ns settling time to 0.1% for a 4V step, and low differential gain/phase errors of 0.03%/0.06°. The device offers a 70MHz 0.1dB gain flatness and 2pF input capacitance. It can directly drive 50Ω or 75Ω back-terminated cables, delivering up to ±2V to a 75Ω load.
The MAX498CWI+ is designed for video switching and routing applications, including broadcast-quality composite-video multiplexing, video editing, multimedia products, and medical imaging. It supports implementation of large switch arrays with a low-power disable mode that places amplifier outputs in a high-impedance state. Channel selection and output enable/disable are controlled by four TTL/CMOS-compatible logic inputs.
This component is available in a 28-SOIC package and utilizes surface mount technology. The MAX498 (four-channel version) dissipates 390mW typical from ±5VDC power supplies with all output buffers enabled, reducing to 130mW with buffers disabled. The MAX499 (three-channel version) has corresponding dissipations of 300mW and 100mW.
