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.
