AD8290ACPZ-R7 Datasheet PDF - ADI

●Product Details

●The AD8290 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 AD8290 is an excellent solution for both the drive and the sensing aspects required for pressure, temperature, and strain gage bridges.

●In addition, because the AD8290 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 AD8290 is available in a lead free 3.0 mm × 3.0 mm × 0.55 mm package and is operational over the industrial temperature range of −40°C to +85°C.
