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.
