MCP656x High Speed Low Power Comparators
0 likes430 views
The MCP656x family of comparators from Microchip feature low quiescent current of 100uA, rail-to-rail input/output, and operating voltages from 1.8V to 5.5V, making them well-suited for battery-powered applications. They are available in single, dual, and quad configurations in small SOT-23 and SC-70 packages. The key advantages are low power consumption, wide operating voltage range, and small size, allowing for longer battery life, full utilization of battery voltage, and smaller system designs.

Editor's Notes
- #2: Welcome to the training module on MCP656x High Speed, Low Power Comparators.
- #3: This training module will introduce Microchip’s 8-bit PIC microcontrollers.
- #4: The MCP656x family of comparators are fabricated using Microchip’s low power CMOS technology. The low operating voltage range of 1.8V to 5.5V and low current consumption makes these devices ideal for battery applications requiring higher speed and low power. The MCP656x families are available in single, dual and quad packaging options and are also available with either push-pull or open-drain outputs.
- #5: The single comparators are offered in space saving SOT-23 and SC-70 packages. The dual versions are available in industry standard pinouts in an 8-pin SOIC and 8-pin MSOP, while the quad comparators are available in 14-pin SOIC and TSSOP packaging.
- #6: As previously mentioned, the MCP656x comparators are designed on a low power CMOS technology which makes them ideal for battery powered applications. In addition, the 47ns propagation delay makes these comparators fast enough for the most demanding applications.
- #7: The combination of low operating voltage and rail-to-rail output operation provide maximum performance and usability by maximizing the dynamic range of the output signal even at low operating voltages.
