The AD866x family is a single-supply, rail-to-rail output amplifier with low noise performance featuring an extended operating range with supply voltages up to 16 V. They also feature low input bias currents, wide signal bandwidth, and low input voltage and current noise.
The AD8665/AD8666/AD8668 family are single‑supply, rail‑to‑rail output amplifiers offering low offset voltage (≤25 mV), ultra‑low input bias current (≤1 pA), and a wide 4 MHz gain‑bandwidth product. They operate from 5 V to 16 V supplies and provide unity‑gain stability, making them suitable for high‑impedance sensor interfaces.
Typical applications include sensor amplification, reference buffers, medical equipment, photodiode amplification, ADC drivers, and consumer audio. The datasheet provides detailed pin configurations, absolute maximum ratings, thermal resistance data, and performance graphs for both small‑signal and large‑signal conditions.
