The Microchip Technology Inc. MCP6476/6R/6U/7/9 operational amplifier (op amp) operates with a single supply voltage as low as 1.8V, while drawing low quiescent current (170 µA, maximum per amplifier). This op amp also has low input offset voltage (±1.6 mV, maximum), and rail-to-rail input and output operation. In addition, the MCP6476/6R/6U/7/9 is unity gain stable and has a gain bandwidth product of 3 MHz (typical). This combination of features supports battery-powered and portable applications.
