OPA692

具有禁用功能的宽带固定增益缓冲放大器

The provides an easy to use, broadband fixed gain video 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 or –1 voltage buffer. Operating on a very low 5.1mA supply current, the OPA692 offers a slew rate and output power 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 OPA692 can deliver a 1V to 4V output swing with over 120mA drive current and > 200MHz bandwidth. This combination of features makes the OPA692 an ideal RGB line driver or single-supply Analog-to-Digital Converter ADC input driver.

The low 5.1mA supply current for the OPA692 is precisely trimmed at +25°C. This trim, along with low drift over temperature, ensures lower maximum supply current than competing products that report only a room temperature nominal supply current. System power may be further reduced by using the optional disable control pin. Leaving this disable pin open, or holding it HIGH, gives normal operation. If pulled LOW, the OPA692 supply current drops to less than 150 µA while the I/O pins go into a high impedance state.
