AD8055AN中文资料亚德诺数据手册PDF规格书

GENERAL DESCRIPTION

The AD8055 (single) and AD8056 (dual) voltage feedback amplifiers offer bandwidth and slew rate typically found in current feedback amplifiers. Additionally, these amplifiers are easy to use and available at a very low cost.

Despite their low cost, the AD8055 and AD8056 provide excellent overall performance. For video applications, their differential gain and phase error are 0.01 and 0.02° into a 150 Ω load and 0.02 and 0.1° while driving four video loads (37.50 Ω).
