Description
The Microchip Technology Inc. MCP6231/1R/1U/2/4
operational
amplifiers (op
bandwidth for the quiescent current. The MCP6231/1R/
1U/2/4 family has a 300 kHz gain bandwidth product
and 65°C (typical) phase margin. This family operates
from a single supply voltage as low as 1.8V, while
drawing 20 µA (typical) quiescent current. In addition,
the MCP6231/1R/1U/2/4 family supports rail-to-rail
input and output swing, with a common mode input
voltage range of V
These op amps are designed in one of Microchip’s
advanced CMOS processes.
