ADA4898-1YRDZ-R7

高电压，低噪声，低失真，单位增益稳定，高速运算放大器 High Voltage, Low Noise, Low Distortion, Unity Gain Stable, High Speed Op Amp

Product Details

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.

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.
