This document introduces the features and characteristics of Microchip TC1037/TC1038/TC1039 series of low-power comparators
The TC1037/TC1038/TC1039 are single, low-power linear building block comparators designed for single-supply operation. They feature ultra-low input bias current (less than 100pA) and low quiescent current, making them ideal for battery-operated equipment and consumer products. The devices operate from a supply voltage as low as 1.8V down to two 1.5V alkaline cells.
| Supply Voltage | 1.8V to 5.5V |
|---|---|
| Input Bias Current | Less than 100pA |
| Quiescent Current (TC1037/TC1038) | 4uA |
| Quiescent Current (TC1039) | 6uA |
| Shutdown Current (TC1038) | 0.05uA |
| Input Offset Voltage | 5mV |
| Reference Voltage (TC1039) | 1.20V |
| Operating Temperature Range | -40°C to +85°C |
The devices operate from a supply voltage down to 1.8V.
Yes, the TC1038 includes an active low shutdown input that reduces supply current to 0.05uA.
The input bias current is less than 100pA.
