Fully differential amplifiers to differentiate your design

Highest performance with the lowest noise, distortion and power to drive your design

Our industry-leading fully differential amplifiers (FDAs) offer low distortion for driving both precision and high-speed analog-to-digital converters (ADCs). Additionally, they're well suited for driving the output of precision and high-speed digital-to-analog converters (DACs). Our FDAs support both single-ended to differential and differential to single-ended functionality.

Low power (<10mA)

The industry’s best performance-to-power-ratio fully differential amplifiers

Wide bandwidth (>1GHz)

Widest-bandwidth fully differential amplifiers for driving high-speed ADCs

Variable gain

Achieve design flexiblity with wide-bandwidth, variable-gain devices
