MCP657x Gen2 Fast Response Comparators—Elevating Performance and Design Flexibility

Microchip Technology is excited to introduce the MCP657x family of fast response comparators, the next generation (Gen2) successors to our popular MCP656x series. These new devices—MCP6571/2/4 (push-pull: single, dual, quad) and MCP6576/7/9 (open-drain: single, dual, quad)—deliver significant improvements that directly address customer pain points in speed, power efficiency, cost and design flexibility.

Solving Customer Challenges

• Performance Bottlenecks: Customers struggling with slow comparator response or high power consumption in their current solutions can benefit from the MCP657x’s superior speed and efficiency.
• Design Constraints: The multiple pinout options and industry standard footprints simplify Printed Circuit Board (PCB) design, making it easier to fit comparators into tight spaces or complex layouts.
• Cost Pressures: The improved cost structure of Gen2 devices helps customers stay competitive in price-sensitive markets.

Key Advantages of MCP657x Gen2

• Faster Propagation Delay at Lower Power: The MCP657x comparators offer industry-leading propagation delay, providing faster response times in time-critical applications such as motor control, signal conditioning and high-speed data acquisition. Importantly, this speed comes with reduced power consumption, helping customers meet stringent energy budgets and thermal requirements.
• Cost-Optimized Structure: Gen2 devices are designed with improved cost structures, making them a compelling choice for high-volume and cost-sensitive designs without sacrificing performance.
• Footprint and Pin-to-Pin Compatibility: MCP657x devices are footprint and pin-to-pin compatible with the existing MCP656x series, allowing for seamless upgrades in existing designs. This compatibility minimizes redesign effort and accelerates time-to-market.
• Industry Standard Pinouts and Footprints: Both generations feature industry standard footprints, allowing easy integration into new and legacy designs.

Unmatched Single Channel Pinout Flexibility

Our single channel comparators are available in three distinct pinout options—Standard, R and U. This flexibility allows engineers to optimize signal routing and PCB layout, reducing design complexity and improving system reliability. Few competitors offer such comprehensive pinout choices, giving Microchip customers a special advantage in board design and layout efficiency.

Why Choose MCP657x Over Competitive Solutions?

Our MCP657x comparators not only outperform previous generations but also offer unmatched flexibility and value compared to other solutions on the market. With faster response, lower power, cost-effective design and versatile pinout options, customers can solve their toughest analog challenges and accelerate their product development cycles.
