RM-8 (MSOP) and R-8 (SOIC) GENERAL DESCRIPTION 5 The AD8057 (single) and AD8058 (dual) are very high perfor- 4 mance amplifiers with a very low cost. The balance between cost and performance make them ideal for many applications. 3 The AD8057 and AD8058 reduce the need to qualify a variety 2 of specialty amplifiers. The AD8057 and AD8058 are voltage 1 feedback amplifiers with the bandwidth and slew rate normally G = +1 0 found in current feedback amplifiers. The AD8057 and AD8058 1 are low power amplifiers having low quiescent current and a wide G = +5 supply range from 3 V to 12 V. They have noise and distortion 2 performance required for high end video systems as well as dc G = +2 3 G = +10 performance parameters rarely found in high speed amplifiers. 4 The AD8057 and AD8058 are available in standard SOIC 5 1110 100000 packaging as well as tiny 5-lead SOT-23 (AD8057) and 8-lead FREQUENCY (MHz) MSOP (AD8058) packages. These amplifiers are available in the Figure 4. Small Signal Frequency Response industrial temperature range of 40C to +85C. Rev.
