VDD = 3.0V, TA = 25°C
Param No. Sym. Characteristic Min. Typ. † Max. Units Conditions
DSB10 VLSB Step Size — (VDACREF+-VDACREF-)/1024 — V
DSB11* VACC Absolute Accuracy(1) — ±4 — LSb
DSB12* RUNIT Unit Resistor Value — 20 — kΩ
DSB13* TST Settling Time(2) — 10 — μs
DSB14* VDBO DAC Buffer Offset — 20 — mV
DSB15 INL Integral Nonlinearity -2.7 1 2.7 LSb 0x022 ≤ DACxDAT ≥ 0x3DD
DSB16 DNL Differential Nonlinearity -1 0.4 1 LSb 0x022 ≤ DACxDAT ≥ 0x3DD
DSB17 EOFF Offset Error -6 1.4 6 LSb 0x022 ≤ DACxDAT ≥ 0x3DD
DSB18 EGN Gain Error -1 -1.2 1 LSb 0x022 ≤ DACxDAT ≥ 0x3DD

* These parameters are characterized but not tested.

† Data in “Typ” column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are not tested.

Note:
  1. Absolute accuracy = Offset Error + Gain Error + DAC Buffer Error (EOFF + EGN + VDBO)
  2. Settling time measured while DACR[7:0] transitions from 'b00000000 to 'b11111111
