The Sitara™ MCU has an ADC which operates in 3.3 V and has a step size which is much less (≈ 66% less) than the step size of a similar 5 V ADC. With clever system design this can be used to a significant advantage. Most sensors have a wide operating range, but the use-case might limit the output variation to a limited range (see section 2). For example, let’s consider a use case where we are using the LM35 temperature sensor and we are operating in room temperature (27 C). If the sensor is directly connected to Sitara™ MCU we get a step resolution of ≈800 uV (=3.3 V/4096) allowing a temperature resolution ≈0.08 C (each ADC LSB will be ≈0.08 C), whereas if we connect an equivalent 5 V ADC (with step size= 5 V/4096 ≈ 1.2 mV) we can only measure a temperature resolution ≈ 0.12 C.
