PRODUCT DESCRIPTION

The AD8057 (single) and AD8058 (dual) are very high perfor­mance 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 µSOIC

(AD8058). These amplifiers are available in the industrial tem-

perature range of –40°C to +85°C.

NOTES

1

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.

2

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 µSOIC Package: θJA = 200°C/W

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. While the
AD8057/AD8058 is internally short circuit protected, this may
not be sufficient to guarantee that the maximum junction tem-

perature (+150°C) is not exceeded under all conditions.

To ensure proper operation, it is necessary to observe the maxi­mum power derating curves.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD8057/AD8058 feature proprietary ESD protection circuitry, permanent damage
may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
