115 / 151 page  GD32H757xx Datasheet 114 Table 4-38. ADC dynamic accuracy at fADC = 80 MHz VREFP = 2.4 V(1)(2) Symbol Parameter Test conditions Min Typ Max Unit ENOB Effective number of bits fADC = 80 MHz VREFP = 2.4 V Input Frequency = 20 kHz Single ended — 11.1 — bits Differential — 11.6 — SNDR Signal-to-noise and distortion ratio Single ended — 68.7 — dB Differential — 71.6 — SNR Signal-to-noise ratio Single ended — 68.8 — Differential — 71.7 — THD Total harmonic distortion Single ended — -83.6 — Differential — -86.8 — (1) Guaranteed by characterization results for BGA packages. The values for LQFP packages might differ. (2) The test was carried out under the LDO power supply mode. Table 4-39. ADC dynamic accuracy at fADC = 80 MHz VREFP = 3.3 V(1)(2) Symbol Parameter Test conditions Min Typ Max Unit ENOB Effective number of bits fADC = 80 MHz VREFP = 3.3 V Input Frequency = 20 kHz Single ended — 11.1 — bits Differential — 11.5 — SNDR Signal-to-noise and distortion ratio Single ended — 68.5 — dB Differential — 71.5 — SNR Signal-to-noise ratio Single ended — 68.6 — Differential — 71.6 — THD Total harmonic distortion Single ended — -83.3 — Differential — -85.9 — (1) Guaranteed by characterization results for BGA packages. The values for LQFP packages might differ. (2) The test was carried out under the LDO power supply mode. Table 4-40. ADC static accuracy at fADC = 60 MHz VREFP = 1.8 V(1)(2) Symbol Parameter Test conditions Typ Max Unit EO Offset error fADC = 60 MHz VREFP = 1.8 V Input Frequency = 1 kHz Single ended ±1.5 — LSB Differential ±0.5 — DNL Differential linearity error Single ended +1.1 / -1 — Differential ±0.9 — INL Integral linearity error Single ended ±0.8 — Differential ±1 — (1) Guaranteed by characterization results for BGA packages. The values for LQFP packages might differ. (2) The test was carried out under the LDO power supply mode. Table 4-41. ADC static accuracy at fADC = 80 MHz VREFP = 2.4 V(1)(2) Symbol Parameter Test conditions Typ Max Unit EO Offset error fADC = 80 MHz VREFP = 2.4 V Input Frequency = 1 kHz Single ended ±1 — LSB Differential ±0.5 — DNL Differential linearity error Single ended ±0.7 — Differential ±0.5 — INL Integral linearity error Single ended ±1.2 — Differential ±1.2 — (1) Guaranteed by characterization results for BGA packages. The values for LQFP packages might differ. |
