OPA693 具有禁用功能的超宽带固定增益视频缓冲放大器
The OPA693 provides an easy to use, broadband, fixed gain buffer amplifier. Depending on the external connections, the internal resistor network may be used to provide either a fixed gain of +2 video buffer or a gain of ±1 voltage buffer. Operating on a low 13mA supply current, the OPA693 offers a slew rate (2500V/µs) and bandwidth (> 700MHz) normally associated with a much higher supply current. A new output stage architecture delivers high output current with a minimal headroom and crossover distortion. This gives exceptional single-supply operation. Using a single +5V supply, the OPA693 can deliver a 2.5VPP swing with over 90mA drive current and 500MHz bandwidth at a gain of +2. This combination of features makes the OPA693 an ideal RGB line driver or single-supply undersampling Analog-to-Digital Converter (ADC) input driver.
