ADI's AD8229 ultra-low noise instrumentation amplifier is designed to measure small signals at large common-mode voltages and high temperatures.
The AD8229 is designed for high temperature operation. The process is electrically insulated to avoid leakage currents at high temperatures. The design architecture was chosen to compensate for low VBE voltages at high temperatures. The AD8229 excels at measuring tiny signals. It has industry-leading 1nV / vHz input noise performance.
The AD8229's high CMRR prevents unwanted signals from corrupting the acquisition. The company said that the CMRR increases with gain and provides high rejection performance when it is most needed.
