(1) Measured with DAC output unloaded. For external reference and internal reference VDD ≥ 1.21 x gain + 0.2 V, between end-point codes: 32d to 4064d for 12-bit resolution, 8d to 1016d for 10-bit resolution.
(2) Specified by design and characterization, not production tested.
(3) Specified with 200-mV headroom with respect to reference value when internal reference is used.
(4) Measured with DAC output unloaded.
(5) The total power consumption is calculated by IDD x (total number of channels powered on) + (sleep-mode current).
(6) When a DAC channel is configured in IOUT mode for long term and then switched to VOUT mode, the VOUT mode can show parametric drift.
