MCP6031/2/3/4 DataSheet
http://www.microchip.com/stellent/images/mchpsiteimages/dwnfolder.gifMCP6031/2/3/4 - 0.9 uA High Precision Op AmpsThe MCP6031 operational amplifier (op amp) has a gain bandwidth of 10 kHz with a low typical operating current of 900 nA and an offset voltage that is less than 150 uV. The MCP6031 uses Microchip's advanced CMOS technology, which provides low bias current, high-speed operation, high open-loop gain and rail-to-rail input and output swing. The MCP6031 operates with a single supply voltage that can be as low as 1.8V, while drawing less than 1 uA of quiescent current. The MCP6031 is available in standard 8-lead SOIC, MSOP, SOT-23 and 2x3 DFN packages.
