GENERAL DESCRIPTION  
10  
10  
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.  
CURRENT  
VOLTAGE  
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.
