MCP6031 High Precision Op Amps Microchip Technology MCP6031 High Precision Op Amps operate with a single supply voltage as low as 1.8V while drawing ultralow quiescent current per amplifier (0.9μA, typical). The MCP6031 also has low input offset voltage (±150μV, maximum) and rail-to-rail input and output operation. This combination of features supports battery-powered and portable applications.
