- Abstract
the design of signal conditioning circuit module is mainly used for weak signal sensor noise amplification and regulation, the module uses LM386 integrated audio amplifier for signal preamplifier, using precision rectifier converts the amplified signal to the DC output, at the same time using differential amplifier with differential amplifier AD620, AD620 is actually a difference the amplifier offset voltage, the current is small, high common mode rejection ratio, so the processing of weak signal, with excellent performance that is amplified and eliminate the noise. To improve the measuring accuracy and reliability of sensor noise.
