Product Overview

The ADA4891-2ARZ is a Dual CMOS High Speed Rail-to-rail Amplifier that offers high performance and versatility. The amplifier features true single-supply capability with an input voltage range that extends 300mV below the negative rail. The rail-to-rail output stage enables the output to swing to within 50mV of each rail, enabling maximum dynamic range. The ADA4891-2 is ideal for imaging applications such as consumer video, CCD buffers and contact image sensor and buffers. Low distortion and fast settling time also make them ideal for active filter applications.
  • High speed and fast settling
  • 0.1dB Gain flatness (25MHz)
  • 0.05% Differential gain error
  • 0.25° Differential phase error
  • Single-supply operation
  • Output swings to within 50mV of supply rails
  • Low distortion (79dBc SFDR at 1MHz)
  • 125mA Linear output current (at -40dBc)
  • Low power (4.4mA per amplifier)
