Low Cost Op Amps Reduce Power

With a nod towards low-voltage designs, the 1 MHz MCP6001 single, MCP6002 dual, and MCP6004 quad op amps operate on supply voltages down to 1.8V with a typical power consumption of 180 µW. Each of the amplifiers provides rail-to-rail inputs and outputs and have a 90° phase margin into a 60 pF, 10 kilohms load, promising to minimize design considerations and the need for stabilizing components. Target applications include battery-operated products and devices powered by a single communications loop. For analog filter designers, the MCP600X family is supported by the FilterLab active filter design tool. The software, which includes schematic diagrams and frequency response displays, is available at no cost from the company's web site. Prices for the MCP6001, MCP6002, and MCP6004 are $0.25, $0.30, and $0.35, respectively, each/1,000. MICROCHIP TECHNOLOGY INC., Chandler, AZ. (480) 792-4111.
