AD8429ARZ, Инструментальный усилитель 1 nV/vHz Low Noise [SO8]
|1 110||×||=||1 110|
The AD8429ARZ is a Low Noise Instrumentation Amplifier designed for measuring extremely small signals over a wide temperature range. This excels at measuring tiny signals and delivers ultralow input noise performance of 1nV/√Hz. The high CMRR 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 allows it to reliably maintain high CMRR at frequencies well beyond those of typical instrumentation amplifiers. It reliably amplifies fast changing signals. Its current feedback architecture provides high bandwidth at high gain. It was designed for excellent distortion performance allowing use in demanding applications such as vibration analysis. Gain is set from 1 to 10000 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.
