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.
