Analog Devices AD8055/AD8056 Voltage Feedback Amplifiers Datasheet
The AD8055 (single) and AD8056 (dual) are low-cost voltage feedback amplifiers offering bandwidth and slew rate typically found in current feedback amplifiers. Key features include a 300 MHz −3 dB bandwidth, 1400 V/μs slew rate, and low noise of 6 nV/√Hz. They operate on dual ±5 V or single +12 V supplies with typical quiescent currents of 5 mA per amplifier.
