AD8290ACPZ-R7

AD8290ACPZ-R7 is a CMOS sensor amplifier with current excitation. It contains both an adjustable current source to drive a sensor and a difference amplifier to amplify the signal voltage. The amplifier is set for a fixed gain of 50. It is an excellent solution for both the drive and the sensing aspects required for pressure, temperature, and strain gauge bridges. In addition, because the device operates with low power, works with a range of low supply voltages, and is available in a low profile package, it is suitable for drive/sense circuits in portable electronics as well. It is used in applications such as bridge and sensor drives, portable electronics.
