Abstract:
Compensated pressure sensor includes a MEMS pressure sensor die having resistors RA and RD connected in series in a first leg of a Wheatstone bridge and resistors RB and RC connected in series in a second leg of the Wheatstone bridge; a first and second fuse; and a first, second third, fourth, fifth and sixth resistor; wherein: a first end of the first resistor is connected in series with the first leg of the bridge and a first end of the second resistor is connected in series with the second leg of the bridge; the first fuse is connected, at a first end, to a first output of the bridge, and at a second end, to a second end of the third resistor and to a first end of the second fuse; the second fuse is connected, at a second end, to a second output of the bridge; a first end of the third resistor is connected to an input to the bridge and to a first end of the fourth resistor; a second end of the fourth resistor is connected to a second end of the first resistor, a second end of the second resistor and a first end of the sixth resistor; and the fifth resistor is connected, at a first end, to the input to the bridge.
