The AD8007 is available in a tiny SC70 package as well as a The AD8007 (single) and AD8008 (dual) are high performance standard 8-lead SOIC. The dual AD8008 is available in both an current feedback amplifiers with ultralow distortion and noise. 8-lead SOIC and an 8-lead MSOP. These amplifiers are rated to Unlike other high performance amplifiers, the low price and work over the industrial temperature range of −40°C to +85°C. low quiescent current allow these amplifiers to be used in a
