GENERAL DESCRIPTION

The ADA4898-1 is an ultralow noise and distortion, unity gain

stable, voltage feedback op amp that is ideal for use in 16-bit

and 18-bit systems with power supplies from ±± ꢀ to ±16 ꢀ.

The ADA4898-1 features a linear, low noise input stage and internal

compensation that achieves high slew rates and low noise.

CURRENT

VOLTAGE

With the wide supply voltage range, low offset voltage, and wide

bandwidth, the ADA4898-1 is designed to work in the most

demanding applications. The ADA4898-1 also features an input

bias current cancellation mode that reduces input bias current

by a factor of 60.

The ADA4898-1 is available in an 8-lead SOIC package that

features an exposed metal paddle on its underside that improves

heat transfer to the ground plane. This is a significant improvement

over traditional plastic packages. The ADA4898-1 is rated to

work over the extended automotive temperature range of

−40°C to +10±°C.
