GENERAL DESCRIPTION
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 to within 50 mV of each rail, enabling maxi-
mum dynamic range.
The ADA4891 family of amplifiers is ideal for imaging applica-
tions, 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.
The ADA4891-1/ADA4891-2/ADA4891-3/ADA4891-4 are avail-
able in a wide variety of packages. The ADA4891-1 is available
in 8-lead SOIC and 5-lead SOT-23 packages. The ADA4891-2
is available in 8-lead SOIC and 8-lead MSOP packages. The
ADA4891-3 and ADA4891-4 are available in 14-lead SOIC and
