Comparators
End of Life (EOL) Notice »
Silicon Labs analog comparators operate from very low supply voltages, draw very little supply current, and have robust input stages that can tolerate input voltages beyond the power supply. The comparators draw as little as 600 nA of supply current. Most part numbers include an on-board ±1% voltage reference. Many of the comparators are electrical and form identical second sources for several analog comparators from Maxim Integrated Products, Inc.
The analog comparator's push-pull output drivers were designed to drive 5mA loads from one supply rail to the other supply rail. Their open-drain output stage make it easy to incorporate this analog comparator into systems that operate on different supply voltages. The comparator devices are available in an ultra-small 5-pin SC70 package.
Features
- Low power and low voltage comparators
- Internal ±1% Voltage References
- Maxim second source options
