Note:
1. Derived from ADCCLK.
2. PSRR is referenced to AVDD when ANASW=0 and to DVDD when ANASW=1 in EMU_PWRCTRL.
3. In ADCn_BIASPROG register.
4. In ADCn_CNTL register.
5. External reference is 1.25 V applied externally to ADCnEXTREFP, with the selection CONF in the SINGLECTRL_REF or
SCANCTRL_REF register field and VREFP in the SINGLECTRLX_VREFSEL or SCANCTRLX_VREFSEL field. The differential
input range with this configuration is ± 1.25 V.
6. Internal reference option used corresponds to selection 2V5 in the SINGLECTRL_REF or SCANCTRL_REF register field. The
differential input range with this configuration is ± 1.25 V. Typical value is characterized using full-scale sine wave input. Minimum
value is production-tested using sine wave input at 1.5 dB lower than full scale.
