MCP6421/2/4 family of operational amplifiers operate with a single supply voltage as low as 1.8V, while drawing low quiescent current per amplifier (5.5 µA, maximum). This family also has low-input offset voltage (±1.0 m V, maximum) and rail-to-rail input and output operation. In addition, the MCP6421/2/4 family is unity gain stable and has a gain bandwidth product of 90 k Hz (typical). This bination of features supports battery-powered and portable applications. The MCP6421/2/4 family has enhanced EMI protection to minimize any electromagnetic interference from external sources. This feature makes it well suited for EMI sensitive applications such as power lines, radio stations, and mobile munications, etc. The MCP6421/2/4 family is offered in single (MCP6421), dual (MCP6422) and quad (MCP6424) packages. All devices are designed using an advanced CMOS process and fully specified in extended temperature range from -40°C to +125°C.
