Just as human beings acquire information from their environment through their senses and process such information using their brain, electronic systems try to do the same by means of sensors and processing digital devices such as microcontrollers (mC) or microprocessors (mP). Nowadays, sensors and processing devices have become essential for the smooth running of our lives and they are present everywhere: industry, automobiles, aircrafts, medical devices, consumer electronics, and home appliances, among others.Sensor interface ICs enable a system to read out information from the input signal generated by complex sensors, providing a suitable output signal that is easy for a host system to display or process.
