1. Specified configuration for Unit gain buffer configuration is: INCBW = 0, HCMDIS = 0, RESINSEL = DISABLE. VINPUT = 0.5 V,
VOUTPUT = 0.5 V.
2. Specified configuration for 3X-Gain configuration is: INCBW = 1, HCMDIS = 1, RESINSEL = VSS, VINPUT = 0.5 V, VOUTPUT = 1.5
V. Nominal voltage gain is 3.
3. If the maximum CLOAD is exceeded, an isolation resistor is required for stability. See AN0038 for more information.
4. Current into the load resistor is excluded. When the OPAMP is connected with closed-loop gain > 1, there will be extra current to
drive the resistor feedback network. The internal resistor feedback network has total resistance of 143.5 kOhm, which will cause
another ~10 µA current when the OPAMP drives 1.5 V between output and ground.
5. In unit gain connection, UGF is the gain-bandwidth product of the OPAMP. In 3x Gain connection, UGF is the gain-bandwidth
product of the OPAMP and 1/3 attenuation of the feedback network.
6. Step between 0.2V and VOPA-0.2V, 10%-90% rising/falling range.
7. When INCBW is set to 1 the OPAMP bandwidth is increased. This is allowed only when the non-inverting close-loop gain is ≥ 3,
or the OPAMP may not be stable.
8. From enable to output settled. In sample-and-off mode, RC network after OPAMP will contribute extra delay. Settling error < 1mV.
9. When HCMDIS=1 and input common mode transitions the region from VOPA-1.4V to VOPA-1V, input offset will change. PSRR
and CMRR specifications do not apply to this transition region.

Note:
1. Supply current increase that occurs when an analog peripheral requests access to APORT. This current is not included in repor-
ted peripheral currents. Additional peripherals requesting access to APORT do not incur further current.
2. Specified current is for continuous APORT operation. In applications where the APORT is not requested continuously (e.g. peri-
odic ACMP requests from LESENSE in EM2), the average current requirements can be estimated by mutiplying the duty cycle of
the requests by the specified continuous current number.
