117 / 127 page ![]() Table 2.44 12-Bit A/D (unit 0) conversion characteristics (2 of 2) Parameter Min. Typ. Max. Unit Reference figure Channel-dedicated sample-and- hold circuits not in use (AN000 to AN007) Conversion time*1 Permissible signal source impedance Max. = 1.0 kΩ 0.84 — — µs — Offset error — — ±11 LSB — Full-scale error — — ±11 LSB — Quantization error — ±0.5 — LSB — Absolute accuracy BGA package — — ±12 LSB — QFP package ±14 DNL differential non-linearity error BGA package — — ±3 LSB — QFP package ±5 INL integral non- linearity error BGA package — — ±4 LSB — QFP package ±7 Note: The specified values in the table apply when there is no access to the external bus during A/D conversion. If access proceeds during A/D conversion, values may not fall within the specified ranges. Note: The LQFP-176 and LQFP-128 do not have pins VCC1833_n, VCC18_ADC1, and VREFH1. Note 1. The conversion time is the total of the sampling time and the comparison time. Table 2.45 12-Bit A/D (unit 1) conversion characteristics Parameter Min. Typ. Max. Unit Reference figure Resolution 12 bits — Conversion time*1 Permissible signal source impedance Max = 1.0 kΩ 0.84 — — µs — Analog input capacitance — — 13 pF — Offset error — — ±11 LSB — Full-scale error — — ±11 LSB — Quantization error — ±0.5 — LSB — Absolute accuracy — — ±12 LSB — DNL differential non-linearity error — — ±3 LSB — INL integral non-linearity error — — ±4 LSB — Note: The specified values in the table apply when there is no access to the external bus during A/D conversion. If access proceeds during A/D conversion, values may not fall within the specified ranges. Note 1. The conversion time is the total of the sampling time and the comparison time. RZ/T2M Datasheet 2.
