AD8091 - High Speed Rail-to-Rail Amplifiers

Description

The AD8091 (single) and AD8092 (dual) are low cost, voltage feedback, high speed amplifiers designed to operate on +3 V, +5 V, or ±5 V supplies.

Features

  • Low cost single (AD8091) and dual (AD8092) amplifiers Fully specified at +3 V, +5 V, and ±5 V supplies Single-supply operation Output swings to within 25 mV of either rail High speed and fast settling on 5 V 110 MHz,.
  • 3 dB bandwidth (G = +1) 145 V/μs slew rate 50 ns settling time to 0.1% Good video specifications (G = +2) Gain flatness of 0.1 dB to 20 MHz; RL = 150 Ω 0.03% differential gain error; RL = 1 kΩ 0.03%differential phase error; RL = 1 kΩ Low distortion.
  • 80 dBc total har.
