GENERAL DESCRIPTION  
The AD866x family are single supply, rail-to-rail output  
amplifiers 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. For lower offset voltage, choose  
the AD8661/AD8662/AD8664 family.

The combination of low offsets, very low input bias currents,  
and wide supply range make these amplifiers useful in a wide  
variety of cost sensitive applications normally associated with  
much higher priced JFET amplifiers. Systems using high  
impedance sensors, such as photo diodes, benefit from the  
combination of low input bias current, low noise, and low offset  
and bandwidth. The wide operating voltage range matches high  
performance ADCs and DACs. Audio applications and medical  
monitoring equipment can take advantage of the high input  
impedance, low voltage and current noise, wide bandwidth, and  
the lack of popcorn noise found in many other low input bias  
current amplifiers.
