Working Principles

The LT1640HIS8#TRPBF operates as a voltage comparator by comparing the voltages at its IN+ and IN- inputs. When the voltage at the IN+ input is higher than the voltage at the IN- input, the output 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 device to detect and indicate voltage differences.
