处理双级传感器信号的单电源电路 |电路欣赏：处理双级传感器信号的单电源电路 | | | |I recently had the task of designing an analog front-end circuit for a | |microcontroller application. A full-bridge sensor in a standard | |configuration produced the input signal. An instrumentation amplifier | |then amplified the low-level signal and fed it to an analog-to-digital | |converter (ADC). After that, a microcontroller read and processed the | |data. | | | |Due to the nature of the sensor and the apparatus to which it was | |connected, the sensor's output voltage was bipolar. I had to amplify | |and ……
