The ADA4898-1/ADA4898-2 feature 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/ADA4898-2 are extremely versatile, and feature a cancellation circuit that reduces input bias current. The ADA4898-1/ADA4898-2 are 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 ADA4898-1/ADA4898-2 are rated to work over the ex...
