使用电阻阵列在激励放大器中提供精确匹配的全桥放大

This example provide excitation using resistor arrays to produce precise gain. The circuit is configured to provide 10V and C5V excitation to the bridge, producing a common mode voltage at the input to the LTC2430/LTC2431 of 2.5V, maximizing the AC input range for applications where induced 60Hz could reach amplitudes up to 2VRMS
