Question: Can I use PSoC 4 opamps in the Deep-Sleep power mode?
You can use PSoC 4 opamps in the Deep-Sleep power mode in PSoC 4100M, 4200M, and PSoC 4 BLE device families. This feature is not supported in PSoC 4000, 4100, and 4200 devices. To enable this feature, open the Opamp Component customizer and enable “Deep sleep operation”, as Figure 1 shows.
Figure 1. Enabling Deep Sleep Operation
Note that Opamps operate with reduced power, bandwidth, and performance in the Deep-Sleep mode. See the respective device datasheet for more details.
