GENERAL DESCRIPTION

The AD8698 is a high precision, rail-to-rail output, low noise, low input bias current operational amplifier. Offset voltage is a respectable 100 µV max and drift over temperature is below 2 µV/°C, eliminating the need for manual offset trimming. The AD8698 is ideal for high impedance sensors, minimizing offset errors due to input bias and offset currents.
