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 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.
