AD8610/AD8620 are low noise, low input bias current, wide bandwidth JFET operational amplifiers.
The AD8610 and AD8620 are precision JFET operational amplifiers offering very low noise (6 nV/√Hz), ultra‑low offset voltage (as low as 100 pV), and low input bias current (10 pA). They operate from a dual‑supply range of +5 V to +13 V and are stable with capacitive loads over 1000 pF, making them suitable for high‑performance ADC inputs, DAC buffering, and audio applications.
The handbook includes detailed electrical specifications, pin configurations for MSOP and SOIC packages, typical performance graphs, and recommended applications such as photodiode amplifiers, instrumentation, and high‑performance filters. Absolute maximum ratings, supply current, and thermal data are also provided.
