AD8669ARUZ

AD8669ARUZ is a rail-to-rail output amplifier that uses the Analog Devices, Inc., patented DigiTrim® trimming technique to achieve low offset voltage. It features an extended operating range with supply voltages upto 16V. It also features low input bias current, low input offset voltage, and low current noise. The combination of low offset, very low input bias current, and a wide supply range make this amplifier useful in a wide variety of applications usually associated with higher-priced JFET amplifiers. Systems using high-impedance sensors, such as photodiodes, benefit from the combination of low input bias current, low noise, low offset, and wide bandwidth. It is used in applications such as sensor front ends, trans-impedance amplifiers, electrometer applications, photodiode amplification, low-power ADC drivers, medical diagnostic instruments, pH and ORP meters and probes, DAC or REF buffers.
