Low Power Analog Solutions Microchip offers a broad portfolio of stand-alone analog and interface solutions that address the thermal management, power management, mixed-signal, linear, interface and safety and security markets. In addition to using low power CMOS technology, Microchip’s analog products are designed to optimize performance while minimizing power consumption. Non-volatile expertise is leveraged to achieve high accuracy specifications without additional manufacturing steps and cost. Chip select/shutdown/sleep features on many of our analog and interface parts enable systems to be selectively shut down to further reduce power consumption. Low operating voltages combined with small form factors such as SC70, DFN and SOT-23 make Microchip’s analog and interface portfolio well-suited for applications with tight power budgets.
