AD8057/AD8058 is a low-cost, single- and dual-channel, high-performance voltage feedback amplifier with a 325 MHz bandwidth, 1000 V/μs slew rate, 0.1 dB gain flatness, 7 nV/√Hz noise, 5.4 mA/amplifier typical supply current @ 5 V, −85 dBc @ 5 MHz distortion, 3 V to 12 V wide supply range, and SOT-23 and SOIC packages.
The AD8057 (single) and AD8058 (dual) are high‑speed voltage‑feedback amplifiers offering 325 MHz bandwidth, low noise (7 nV/√Hz), and low distortion, making them suitable for imaging, DVD/CD, photodiode preamps, and professional camera filters. They operate from 3 V to 12 V, draw only a few milliamps of quiescent current, and are available in SOIC, SOT‑23, and MSOP packages.
The handbook provides detailed specifications, absolute maximum ratings, typical performance curves, outline dimensions, and an ordering guide for each package variant. It also includes connection diagrams and revision history for reference.
