AD8429BRZ

AD8429 is an ultralow noise, instrumentation amplifier. This device excels at measuring tiny signals. It delivers ultralow input noise performance of 1nV/√Hz. The high CMRR of the device 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 device allows it to reliably maintain high CMRR at frequencies well beyond those of typical instrumentation amplifiers. Gain is set from 1 to 10,000 with a single resistor. A reference pin allows the user to offset the output voltage. This feature can be useful to shift the output level when interfacing to a single supply signal chain. It is widely used in application such as medical instrumentation, precision data acquisition, microphone preamplification, vibration analysis etc.
