MCP6286 Low Noise, Low Power Op Amp Features • • • • • • • • • Low Noise: 5.4 nV/√Hz (typical) Low Quiescent Current: 520 µA (typical) Rail-to-Rail Output Wide Supply Voltage Range: 2.2V to 5.5V Gain Bandwidth Product: 3.5 MHz (typical) Unity Gain Stable Extended Temperature Range: -40°C to +125°C No Phase Reversal Small Package Description The Microchip Technology Inc. MCP6286 operational amplifier (op amp) has low noise (5.4 nV/√Hz, typical), low power (520 µA, typical) and rail-to-rail output operation. It is unity gain stable and has a gain bandwidth product of 3.5 MHz (typical). This device operates with a single supply voltage as low as 2.2V, while drawing low quiescent current. These features make the product well suited for single-supply, low noise, battery-powered applications. The MCP6286 op amp is offered in a space saving SOT-23-5 package. It is designed with Microchip’s advanced CMOS process and available in the extended temperature range, with a power supply range of 2.2V to 5.5V.
