Product Summary

The AD8290ACPZ is a CMOS sensor amplifier with current excitation. The AD8290ACPZ 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. The AD8290ACPZ is an excellent solution for both the drive and the sensing aspects required for pressure, temperature, and strain gage bridges. In addition, because the AD8290ACPZ 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. The applications of the AD8290ACPZ include bridge and sensor drives, portable electronics.
