Ultra low-noise instrumentation amplifier designed for measuring small signals

Designed for measuring small signals in the presence of large common-mode voltages and high temperatures, the Analog Devices AD8229 ultra low-noise instrumentation amplifier is now available from RS Components. The AD8229 is 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. The AD8229 excels at measuring tiny signals. It delivers industry-leading 1nV/vHz input noise performance. The high CMRR of the AD8229 prevents unwanted signals from corrupting the acquisition. The CMRR increases as the gain increases, offering high rejection when it is most needed, says the company.
