operational

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.

... A 5V difference would between nearby traces is 10 cause current to flow, which is greater than the MCP6231/1R/1U/2/4 family’s bias current at +25°C (1 pA, typical). The easiest way to reduce surface leakage is to use a guard ring around sensitive pins (or traces). The guard ring is biased at the same voltage as the sensitive pin. ...
