Abstract
The utility model relates to a voltage conditioning circuit, and particularly relates to an AD voltage conditioning circuit. The conditioning circuit comprises a voltage-dividing circuit and a voltage translation circuit. The voltage-dividing circuit and the voltage translation circuit share an output end. The voltage-dividing circuit and the voltage translation circuit are integrated together and share the output end so that the voltage-dividing circuit and the voltage translation circuit can be isolated without using an isolation circuit, AD voltage can be conditioned to an appropriate value, three arithmetic units required to be used by an original conditioning circuit is reduced to only two arithmetic units, and four resistors required to be used by the voltage-dividing circuit and the translation circuit of the original conditioning circuit are reduced to only three resistors. Therefore, the circuit is simplified, cost is greatly reduced and assembling efficiency of circuit boards is enhanced in batch production.
