The ADA4891-1 (single), ADA4891-2 (dual), ADA4891-3 (triple), and ADA4891-4 (quad) are CMOS, high speed amplifiers that offer high performance at a low cost. The amplifiers feature true single-supply capability, with an input voltage range that extends 300 mV below the negative rail. In spite of their low cost, the ADA4891 family provides high performance and versatility. The rail-to-rail output stage enables the output to swing within 50 mV of each rail, enabling maximum dynamic range. The ADA4891 family of amplifiers is ideal for imaging
