GENERAL DESCRIPTION

The AD8429 is an ultralow noise, instrumentation amplifier designed for measuring extremely small signals over a wide temperature range (?40°C to +125°C).

The AD8429 excels at measuring tiny signals. It delivers ultralow input noise performance of 1 nV/√Hz. The high CMRR of the AD8429 prevents unwanted signals from corrupting the acquisition. The CMRR increases as the gain increases, offering high rejection when it is most needed. The high performance pin configuration of the AD8429 allows it to reliably maintain high CMRR at frequencies well beyond those of typical instrumentation amplifiers.
