ADA4898-1 High Voltage, Low Noise, Low Distortion, Unity Gain Stable, High Speed Op Amp

The ADA4898-1 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 ADA4898-1 features a linear, low noise input stage and internal compensation that achieves high slew rates and low noise.Instrumentation Active filters DAC buffers SAR ADC drivers Optoelectronics

With the wide supply voltage range, low offset voltage, and wide bandwidth, the ADA4898-1 is extremely versatile, and it features a cancellation circuit that reduces input bias current. The ADA4898-1 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 ADA4898-1 is rated to work over the extended industrial temperature range of −40°C to +105°C.
