MAX498集成電路（IC）的電源控制器監(jiān)視器規(guī)格書PDF中文資料

General Description

The MAX498/MAX499 are high-speed, quad/triple, single-pole/double-throw video switches with on-board closed-loop buffer amplifiers. The buffer amplifiers feature +6dB gain (AVCL = 2V/V), 250MHz -3dB bandwidth, 70MHz 0.1dB gain flatness, and 1250V/μs slew rate. Fast switching time (3ns) and fast settling time (12ns for a 4V step) make these devices excellent choices for a wide variety of video applications. The low differential gain/phase errors (0.03/0.06°) and wide bandwidth make them ideal for both composite-video and RGB applications. The amplifiers are capable of delivering ±2.5V into back-terminated 50? or 75? cables, and they deliver ±2V to a 75? load, allowing multiple cables to be driven from a single output.
