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 ADA4891-1/ADA4891-2/ADA4891-3/
ADA4891-4 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 maximum dynamic range.
The ADA4891-1/ADA4891-2/ADA4891-3/ADA4891-4 family of
amplifiers 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.
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
