This datasheet details the specifications, features, and application information for low-cost, high-speed AD8055 single and AD8056 dual voltage feedback…
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.
| -3 dB Bandwidth (G=+1, VO=0.1 V p-p) | 220 MHz Typ / 300 MHz Max |
|---|---|
| Slew Rate (G=+1) | 1400 V/μs Max |
| Input Voltage Noise (f=100 kHz) | 6 nV/√Hz |
