OPA691IDR

宽带电流反馈运算放大器，具有禁用 Wideband, Current Feedback OPERATIONAL AMPLIFIER With Disable

Wideband, Current Feedback OPERAONAL AMPLIFIER With Disable

DESCRIPTION

The OPA691 sets a new level of performance for broadband current feedback op amps. Operating on a very low 5.1mA supply current, the OPA691 offers a slew rate and output power normally associated with a much higher supply current. A new output stage architecture delivers a high output current with minimal voltage headroom and crossover distortion. This gives exceptional single-supply operation. Using a single +5V supply, the OPA691 can deliver a 1V to 4V output

swing with over 150mA drive current and 190MHz band width. This combination of features makes the OPA691 an ideal RGB line driver or single-supply Analog-to-Digital Converter ADC input driver.
