General Description

The TC1037/TC1038/TC1039 are single, low-power comparators designed for low-power applications.

These comparators are specifically designed for operation from a single supply. However, operation from dual supplies also is possible, and power supply current is independent of the magnitude of the power supply voltage. The TC1037/TC1038/TC1039 operate from two 1.5V alkaline cells down to VDD = 1.8V. Active supply current is 4µA for the TC1037/TC1038 and 6µA for the TC1039. Input and output swing of these devices is rail-to-rail.
