Working Principles

The MAX9109EXT+T is a high-speed differential comparator that compares the voltages at its IN+ and IN- inputs. When the voltage at the IN+ input exceeds the voltage at the IN- input, the output (OUT) switches to a high state. Conversely, when the voltage at the IN- input is higher, the output switches to a low state. This behavior allows the comparator to detect and respond to changes in input voltages quickly.
