The MAX4141 is a wideband 330MHz, 700V/µs 4x1 multiplexer optimized for high-definition, broadcast-quality, composite (HDTV, NTSC, PAL, SECAM) video switching arrays. The device includes four open-loop buffer amplifiers with a 0.1dB gain flatness of 150MHz, and enable and switch-control logic. The MAX4141 operates from ±5V supplies and features differential phase and gain error of only 0.01°/0.01%. The ultra-low switching glitch (less than 13mV) is positive to avoid confusion with any sync pulses.
Ideal as a building block for large switch arrays, the MAX4141 features a constant, high input impedance and a disable function that puts the output into a high-impedance state and reduces the operating current to only 250µA. The open-loop architecture allows the output to drive capacitive loads without oscillation.
Other key features include -66dB crosstalk (30MHz), -74dB isolation (30MHz), less than 10mV offset voltage, and a 110MHz full-power bandwidth (1.4Vp-p). The MAX4141 is available in a 14-pin narrow SO package.
