Applications
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.
