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.

1 Specification is for device in free air:
8-lead SOIC package: θJA = 160°C/W
5-lead SOT-23-5 package: θJA = 240°C/W
8-Lead MSOP package: θJA = 200°C/W
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
AD8057/AD8058
MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the
AD8057/AD8058 is limited by the associated rise in junction
temperature. Exceeding a junction temperature of 175°C for
an extended period can result in device failure. Although the
AD8057/AD8058 is internally short-circuit protected, this may
not be sufficient to guarantee that the maximum junction temper-
ature (150°C) is not exceeded under all conditions. To ensure
proper operation, it is necessary to observe the maximum power
derating curves.
