AD8669ARZ

AD8669 is a rail-to-rail output amplifier that uses the analog devices, Inc., patented DigiTrim® trimming technique to achieve low offset voltage. This feature an extended operating range with supply voltages up to 16V. This 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 makes these amplifiers 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. Application includes sensor front ends, trans-impedance amplifiers, electrometer applications, photodiode amplification, low-power ADC drivers, medical diagnostic instruments, pH and ORP meters and probes, and DAC or REF buffers.
