DC Bridge Amplifier DCBA1ME, DCBA2ME and DCBA1MF


DC Bridge Amplifier DCBA1ME and DCBA2ME

The DCBA1ME and the DCBA2ME amplify the voltage differences of full resistor bridges. The DCBA1ME sup­ports one bridge whereas the DCBA2ME supports two bridges.

Usually, point A of the bridge is connected with the bridge supply (1 V DC, 2 V DC, or 5 V DC) and point C is connected with ground (0 V). Then, one of the points B and D is connected with the inverting sensor input, and the other point is connected with the noninverting sensor input. Using this configuration, the signal to be amplified is given by the voltage difference between noninverting and inverting sensor input.
