Microchip, represented by Soanar in Australia and New Zealand, announced the MCP6561/2/4/6/7/9 (MCP656X) family of high-speed (45nS) comparators with rail-to-rail input and output, low operating voltage down to 1.8V, low quiescent current and package options with push-pull and open-drain outputs.
The cost-effective comparators are suitable for battery-powered applications requiring low power and high-speed operation. Their low quiescent current of 100 microamperes (µA) generates less heat, extends battery life and minimizes thermal-related challenges. Applications in the industrial (power supplies, motor control), consumer (RF readers, alarm systems and portable electronics) and automotive markets (zero-crossing detectors, high-speed sampling circuits) are appropriate for the MCP656X comparators.
Development tool support includes the voltage supervisor SOT-23-5/6 evaluation board (Part VSUPEV2). This board provides a blank PCB for easily evaluating the 5-pin SOT-23 packaged MCP656X comparator. For the 8-pin SOIC and MSOP packages, designers can utilise the 8-pin SOIC/MSOP/TSSOP/DIP evaluation board (Part # SOIC8EV). Additionally, the free online Mindi Simulator Tool is available on the website for analysing various analogue circuits used in power-management and linear applications.
The single channel MCP6561 and MCP6566 comparators are available in 5-pin SOT-23 and SC-70 packages while the dual channel MCP6562 and MCP6567 comparators are available in 8-pin SOIC and MSOP packages. The quad channel MCP6564 and MCP6569 comparators are available in 14-pin SOIC and TSSOP packages.
