AD8675ARZ Amplifier Description


Over the entire operating temperature range, the AD8675 precision operational amplifier has ultralow offset, drift, and voltage noise, as well as very low input bias currents. The AD8675 is a precision, wide bandwidth operational amplifier with rail-to-rail output swings and extremely low noise. The operating voltage range is fully specified from 5 V to 15 V.
The AD8675 has a rail-to-rail output similar to the OP184, but with a wider bandwidth and lower voltage noise, as well as the precision and low power consumption of the industry-standard OP07 amplifier. The AD8675 has very low input bias current and low input current noise compared to other low noise rail-to-rail op amps.
