Key Features

  • High DC precision with low offset voltage (100 µV max) and low offset drift (1.5 µV/°C max).
  • Low input bias current (200 pA max) with minimal drift over temperature, combining the benefits of JFET and bipolar amplifiers.
  • Low noise characteristics: 0.5 µV p-p voltage noise and 3 pA p-p current noise from 0.1 Hz to 10 Hz.
  • High common-mode rejection ratio (CMRR) of 110 dB to 132 dB.
  • Internally compensated for unity gain and available in five performance grades.
  • Available in 8-lead PDIP and surface-mount SOIC packages.

Applications

The AD706ARZ is well-suited for various precision applications, including:

  • Low frequency active filters in 12-bit and 14-bit data acquisition systems.
  • Precision instrumentation where high DC accuracy and low noise are critical.
  • High quality integrators in analog circuits.
  • Circuits that would typically require a chopper amplifier but benefit from the lower noise of the AD706ARZ.
