ANALOGUE MEASUREMENT DATA DETECTION SYSTEM AND BATTERY VOLTAGE DETECTION SYSTEM

摘要

An analogue measurement data detection system according to the present invention includes: a reference voltage generation circuit configured to generate and output a reference voltage; an analogue/digital converter configured to compare an analogue signal with die reference voltage outputted from the reference voltage generation circuit, and based on a differential voltage between the analogue signal and the reference voltage, generate and output a digital signal corresponding to the analogue signal. The reference voltage generation circuit is configured to cause the reference voltage to have such a temperature characteristic as to compensate for temperature characteristics of at least the analogue/digital converter and the reference voltage generation circuit.
