Low Power Analog Solutions

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.
