GENERAL DESCRIPTION

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 will 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 SOT-23-5 (AD8057) and MSOP

(AD8058) packages. These amplifiers are available in the indus-

trial temperature range of –40°C to +85°C.
