AD8651/AD8652 are 50MHz low noise, low distortion CMOS amplifiers with single-supply operation from 2.7V to 5.5V, and are used in optical communications, laser source drivers/controllers, broadband communications, high speed ADCs and DACs, microwave link interface, cell phone PA control, video line drivers and audio.
The AD865x family consists of high‑precision, low‑noise, rail‑to‑rail CMOS operational amplifiers. They operate from a single‑supply voltage of 2.7 V to 5.5 V, provide a gain‑bandwidth product of 50 MHz, and feature offset voltage as low as 100 µV, input bias current of 1 pA, and a typical voltage noise density of 4.5 nV/√Hz.
These amplifiers are offered in 8‑lead MSOP and 8‑lead SOIC packages and are suited for optical communications, laser driver circuits, high‑speed ADC/DAC interfaces, microwave links, cell‑phone PA control, and video line drivers. The datasheet includes pin configurations, absolute maximum ratings, thermal resistance, ESD precautions, typical performance curves, and an ordering guide.
