AD8698:  Precision Rail-to-Rail Output Operational Amplifier

Product Description

AD8698 is a 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 like 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. MSOP version is only available in tape and reel.

Features

  • Low Offset Voltage: 100 µV max
  • Low Offset Voltage Drift: 2 µV/°C max
  • Low Input Bias Current: 700 pA max
  • Low Noise: 8 nV/vHz
  • High CMRR: 118 dB Min
  • No Phase Reversal
