.jpg) Micropower amplifiers
Microchip’s new MCP6XX family of 2.5 V micropower operational amplifiers use advanced offset voltage trimming techniques to achieve an offset voltage of less than 250 µV. The family also has an extremely low supply current requirement of only 25 µA over a 2.5 to 3.3 V range and a low bias current of only 1 pA. The offset voltage and bias current eliminate the need for offsetting circuitry, and the low supply current makes these devices ideal for use in battery powered applications.The four devices in the MCP6XX family are available in single (MCP606), single with an. innovative chip-select capability (MCP607), dual (MCP608) and quad (MCP609) operational amplifier configurations. They feature rail-to-rail swing at output and unity gain stability.
All devices are fully specified from - 40ºC to +85 ºC with power supplies from 2.5 volts to 5.5 V. To support the MCP6XX family, Microchip offers the FilterLab Active Filter Design Tool that simplifies active filter design for embedded systems designers using op amps for analog filter purposes. Available at no cost from Microchip’s website (www.microchip.com), the FilterLab software provides full schematic diagrams of the filter circuit with component values and displays the frequency response.
