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 ±5 V to ±16 V.
The ADA4898-1 features a linear, low noise input stage and internal
compensation that achieves high slew rates and low noise.
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 +105°C.
