GENERAL DESCRIPTION  
5
4
The AD8057 (single) and AD8058 (dual) are very high perfor-  
mance amplifiers with a very low cost. The balance between  
cost and performance make them ideal for many applications.  
The AD8057 and AD8058 reduce the need to qualify a variety  
of specialty amplifiers. The AD8057 and AD8058 are voltage  
feedback amplifiers with the bandwidth and slew rate normally  
found in current feedback amplifiers. The AD8057 and AD8058  
are low power amplifiers having low quiescent current and a wide  
supply range from 3 V to 12 V. They have noise and distortion  
performance required for high end video systems as well as dc  
performance parameters rarely found in high speed amplifiers.

The AD8057 and AD8058 are available in standard SOIC  
packaging as well as tiny 5-lead SOT-23 (AD8057) and 8-lead  
MSOP (AD8058) packages. These amplifiers are available in the  
industrial temperature range of −40°C to +85°C.
