4 Electrical Characteristics
ESP-IDF provides couple of calibration methods for ADC. Results after calibration using hardware + software
calibration are shown in Table 19. For higher accuracy, users may apply other calibration methods provided in
ESP-IDF, or implement their own.

4.6 Current Consumption
4.6.1 RF Current Consumption in Active Mode
The current consumption measurements are taken with a 3.3 V supply at 25 °C of ambient temperature at the RF
port. All transmitters’ measurements are based on a 100% duty cycle.

The CPU work mode: Single core runs 32-bit data access instructions at 80 MHz, the other core is in
idle state.
4.6.2 Current Consumption in Other Modes
The measurements below are applicable to ESP32-S3 and ESP32-S3FH8. Since ESP32-S3R2, ESP32-S3R8,
ESP32-S3R8V, and ESP32-S3FN4R2 are embedded with PSRAM, their current consumption might be
higher.

In Light-sleep mode, all related SPI pins are pulled up. For chips embedded with PSRAM, please add
corresponding PSRAM consumption values, e.g., 140 µA for 8 MB 8-line PSRAM (3.3 V), 200 µA for 8
MB 8-line PSRAM (1.8 V) and 40 µA for 2 MB 4-line PSRAM (3.3 V).
