Product Details
●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.
