Abstract
An electronic device includes an ADC, a multiplexer, a voltage reference circuit, an analog circuit, and a digital circuit. The ADC has a signal input, a reference input, and an output. The multiplexer has signal inputs and a signal output coupled to the signal input of the ADC. The voltage reference circuit has an output coupled to the reference input of the ADC, a first strain sensor coupled to a first signal input of the multiplexer, a second strain sensor coupled to a second signal input of the multiplexer, and a temperature sensor. The analog circuit has an input coupled to a battery, and an output coupled to a fourth signal input of the multiplexer. The digital circuit is coupled to the output of the ADC and stores correction parameters for correcting a converted battery voltage value from the ADC.
