The SAR8 User Module is an 8-bit successive approximation register (SAR) ADC converter that converts an input voltage to a digital code using a dedicated analog PSoC block. It features typical conversion times of 2.7 μs (limited with firmware processing) and produces an 8-bit unsigned value for each sample. In motor control applications you may need to trigger the ADC to execute one analog-to-digital conversion at a certain time during the PWM period in order to obtain best performance.
