AD8665ARZ

AD8665 is a single supply, rail-to-rail output amplifier with low noise performance featuring an extended operating range with supply voltages upto 16V. It also feature low input bias currents, wide signal bandwidth, and low input voltage and current noise. 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. It is widely used in application such as sensor amplification, reference buffers, medical equipment, physiological measurements, signal filters and conditioning, consumer audio, photodiode amplification, ADC driver and level shifting circuits.
