AD8057 Low Cost, Single, High Performance Voltage Feedback, 325 MHz Amplifier

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 MSOP (AD8058) packages. These amplifiers are available in the industrial temperature range of -40°C to +85°C.
