GENERAL DESCRIPTION AD8665ARJZ

The AD866x family is 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.
