MCP6241/2/4
50 µA, 550 kHz Rail-to-Rail Op Amp
Features
Description
• Gain Bandwidth Product: 550 kHz (typ.)
• Supply Current: IQ = 50 µA (typ.)
The Microchip Technology Inc. MCP6241/2/4
operational amplifiers (op amps) provide wide
bandwidth for the quiescent current. The MCP6241/2/4
has a 550 kHz Gain Bandwidth Product (GBWP) and
68° (typ.) phase margin. This family operates from a
single supply voltage as low as 1.8V, while drawing
50 µA (typ.) quiescent current. In addition, the
MCP6241/2/4 family supports rail-to-rail input and
output swing, with a common mode input voltage range
of VDD + 300 mV to VSS – 300 mV. These op amps are
designed in one of Microchip’s advanced CMOS
processes.
