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.
