11.0
The OPA module has the following features:
• Two independent Operational Amplifiers
• External connections to all ports
• 3 MHz Gain Bandwidth Product (GBWP)
11.1
The OPA1CON register, shown in Register 11-1,
controls OPA1. OPA2CON, shown in Register 11-2,
controls OPA2.

The OPA module is enabled by setting the OPAON bit
of the OPAxCON Register. When enabled, OPAON
forces the output driver of RC3/AN7/C12IN3-/OP1 for
OPA1, and RC2/AN6/C12IN2-/OP2 for OPA2, into
tristate to prevent contention between the driver and
the OPA output. The ADC and comparator inputs which
share the op amp pins operate normally when the op
amp is enabled.

When OPA1 or OPA2 is enabled, the
RC3/AN7/C12IN3-/OP1 pin, or
RC2/AN6/C12IN2-/OP2 pin, respectively,
is driven by the op amp output, not by the
PORTC driver. Refer to Table 19-11 for the
electrical specifications for the op amp
output drive capability.
