11.3
A device Reset forces all registers to their Reset state.
This disables both op amps.
11.4
Common AC and DC performance specifications for
the OPA module:
• Common Mode Voltage Range
• Leakage Current
• Input Offset Voltage
• Open Loop Gain
• Gain Bandwidth Product (GBWP)
Common mode voltage range is the specified voltage
range for the OPA+ and OPA- inputs, for which the OPA
module will perform to within its specifications. The
OPA module is designed to operate with input voltages
between 0 and V
voltages greater than V
beyond the normal operating range.

Leakage current is a measure of the small source or
sink currents on the OPA+ and OPA- inputs. To mini-
mize the effect of leakage currents, the effective imped-
ances connected to the OPA+ and OPA- inputs should
be kept as small as possible and equal.
Input offset voltage is a measure of the voltage differ-
ence between the OPA+ and OPA- inputs in a closed
loop circuit with the OPA in its linear region. The offset
voltage will appear as a DC offset in the output equal to
the input offset voltage, multiplied by the gain of the
circuit. The input offset voltage is also affected by the
common mode voltage.
Open loop gain is the ratio of the output voltage to the
differential input voltage, (OPA+) - (OPA-). The gain is
greatest at DC and falls off with frequency.
Gain Bandwidth Product or GBWP is the frequency
at which the open loop gain falls off to 0 dB.

When enabled, the op amps continue to operate and
consume current while the processor is in Sleep mode.
