Abstract
Disclosed herein are embodiments of an auto ranging system and method for an analog signal. A microprocessor is configured to digitally control the programmable gains of an operational amplifier based on the digital output of an A/D converter which may reside on or packaged along with the microprocessor. The amplifier receives a raw analog signal from a sensor and provides an amplified analog signal to the A/D converter. The gain of the amplifier generally corresponds to some range of the sensor signal. The A/D converter outputs a number of bits representative of the input signal. A microprocessor which is configured to digitally control the programmable gains of the amplifier receives and examines the output from the A/D converter and automatically adjusts the gain of the amplifier accordingly and as needed to keep or maintain the output from the A/D converter in a predetermined range.
