91 / 110 page  DS13259 Rev 2 91/110 STM32WB10CC Electrical characteristics 102 6.3.18 Analog switches booster 6.3.19 Analog-to-Digital converter characteristics Unless otherwise specified, the parameters given in Table 66 are preliminary values derived from tests performed under ambient temperature, fPCLK frequency and VDDA supply voltage conditions summarized in Table 20: General operating conditions. Note: It is recommended to perform a calibration after each power-up. Table 65. Analog switches booster characteristics(1) 1. Specified by design, not tested in production. Symbol Parameter Min Typ Max Unit VDD Supply voltage 2.0 - 3.6 V tSU(BOOST) Booster startup time - - 240 µs IDD(BOOST) Booster consumption for 2.0 V ≤ VDD < 2.7 V -- 500 µA Booster consumption for 2.7 V ≤ VDD ≤ 3.6 V -- 900 Table 66. ADC characteristics(1) (2) Symbol Parameter Conditions Min Typ Max Unit VDDA Analog supply voltage - 2.0 - 3.6 V fADC ADC clock frequency - 0.14 - 35 MHz fs Sampling rate 12 bits - - 2.50 Msps 10 bits - - 2.92 8 bits - - 3.50 6 bits - - 4.38 fTRIG External trigger frequency fADC = 35 MHz 12 bits -- 2.33 MHz 12 bits - - fADC / 15 VAIN (3) Conversion voltage range(2) -0 - VDDA V RAIN External input impedance -- - 50 kΩ CADC Internal sample and hold capacitor -- 5 - pF tSTAB Power-up time - 2 Conversion cycle tCAL Calibration time fADC = 35 MHz 2.35 µs -82 1 / fADC |
