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.
The rail-to-rail output maximizes dynamic range in a variety of
applications, such as photodiode amplifiers, DAC I/V
amplifiers, filters, and ADC input amplifiers.
The AD8698 dual amplifiers are offered in 8-lead MSOP and
narrow 8-lead SOIC packages. The MSOP version is available
in tape and reel only.
