Description
The Microchip Technology Inc. MCP6241/1R/1U/2/4
operational amplifiers (op amps) provide wide
bandwidth for the quiescent current. The MCP6241/1R/
1U/2/4 has a 550 kHz gain bandwidth product and 68°
(typical) phase margin. This family operates from a
single supply voltage as low as 1.8V, while drawing
50 µA (typical) quiescent current. In addition, the
MCP6241/1R/1U/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.
