GENERAL DESCRIPTION
The AD8229 is an ultralow noise instrumentation amplifier designed for measuring small signals in the presence of large common-mode voltages and high temperatures.
The AD8229 has been designed for high temperature operation. The process is dielectrically isolated to avoid leakage currents at high temperatures. The design architecture was chosen to compensate for the low VBE voltages at high temperatures.
