AD22055R中文资料亚德诺数据手册PDF规格书

GENERAL DESCRIPTION

The AD22055 accepts a differential signal from a bridge transducer whose common-mode signal can be anywhere between the power supplies.

The extended temperature range allows for local signal conditioning for oil and hydraulic pressure sensors as well as other automotive sensors.

The use of an external gain resistor allows the user to compensate transducer gain error and temperature drift.
