GENERAL DESCRIPTION
The ADA4898 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 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 is extremely versatile, and it features a
cancellation circuit that reduces input bias current.
The ADA4898 is available in an 8-lead SOIC package that
features an exposed metal paddle to improve power dissipation and
heat transfer to the negative supply plane. This EPAD offers a
significant thermal relief over traditional plastic packages. The
ADA4898 is rated to work over the extended industrial
temperature range of 40°C to +105°C.
