Integral nonlinearity is ±1 LSB max, differential nonlinearity ±0.5 LSB max — the monotonicity guarantee across the 128 codes means the output never steps backward, critical when the DAC sets a threshold in a comparator or a regulator feedback divider. The 7-bit resolution (128 steps) is coarse compared to a 12-bit DAC, but the current-mode output eliminates the external op-amp needed for a voltage-output DAC driving a current loop — the trade-off is resolution for simplicity.","metaTitle":"DS4422N+T&R Analog Devices 7-bit I²C DAC","metaDescription":"Active 7-bit I²C DAC with current sink/source output.
