DESCRIPTION
The OPA2683 provides a new level of performance for dual, very low-power, wideband, current-feedback amplifiers. This CFBPLUS amplifier is among the first to use an internally closed-loop input buffer stage that significantly enhances performance over earlier low-power, current-feedback (CFB) amplifiers. This new architecture provides many of the advantages of a more ideal CFB amplifier while retaining the benefits of very low-power operation.

FEATURES
● REDUCED BANDWIDTH CHANGE VERSUS GAIN
● 150MHz BANDWIDTH G = +2
● > 80MHz BANDWIDTH TO GAIN > +10
● LOW DISTORTION: < –65dBc at 5MHz
● HIGH OUTPUT CURRENT: 110mA
● SINGLE-SUPPLY OPERATION: +5V to +12V
● DUAL-SUPPLY OPERATION: ±2.5V to ±6V
● LOW SUPPLY CURRENT: 1.9mA Total
● POWER SHUTDOWN VERSION: MSOP-10

APPLICATIONS
● LOW-POWER BROADCAST VIDEO DRIVERS
● µPOWER ACTIVE FILTERS
● SHORT-LOOP ADSL CO DRIVERS
● MULTICHANNEL SUMMING AMPLIFIERS
● PROFESSIONAL CAMERAS
● DIFFERENTIAL ADC INPUT DRIVERS
