The AD8047 and AD8048 are 250 MHz general purpose voltage feedback op amps with low distortion and cap load drive, making them ideal for buffering high-speed ADCs. They are suitable for 12-bit/10 MSPS or 8-bit/60 MSPS ADCs. The balanced high impedance inputs of the voltage feedback architecture allow maximum flexibility when designing active filters. The AD8047 and AD8048 are offered in industrial temperature ranges (-40°C to +85°C) and are available in 8-lead PDIP and SOIC packages.
The AD8047 and AD8048 are high‑speed, wide‑bandwidth voltage‑feedback operational amplifiers. The AD8047 is unity‑gain stable, while the AD8048 is stable at gains of two or greater. Both devices feature low distortion, low noise, and the ability to drive capacitive loads up to 50 pF.
These amplifiers are suited for low‑power ADC input drivers, differential amplifiers, RF/IF stages, pulse amplification, and professional video applications. They are offered in 8‑lead PDIP (N) and 8‑lead SOIC (R) packages with operating temperature ranges from –40 °C to +85 °C.
