  • Product introduction

ADA4891-1WARJZ-R7 Low Cost CMOS, High Speed, Rail-to-Rail Amplifier (Quad)

The ADA4891-1 (single), ADA4891-2 (dual), ADA4891-3 (triple), and ADA4891-4 (quad) are CMOS, high speed, high performance, low cost amplifiers with single-supply capability and an extended input voltage range below 300 mV in the negative rail.

Despite its low cost, the ADA4891 family offers high performance and a wide range of features. The rail-to-rail output stage allows the output to swing to within 50 mV of each rail to provide maximum dynamic range.

The ADA4891 family of amplifiers is ideal for imaging applications such as consumer video equipment, CCD buffers, and contact image sensors/buffers. Low distortion and fast settling time make these devices ideal for active filter applications.

The ADA4891-1/ADA4891-2/ADA4891-3/ADA4891-4 are available in a 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 14-lead TSSOP packages.

It is specified over the extended temperature range of −40°C to +125°C.
