5-bit I²C DAC with current output
The DS4402N+: Two independent DAC channels are integrated in the 14-TDFN (3x3 mm) package, each controlled via a single I²C bus. The 5-bit resolution yields 32 programmable current levels per channel, making this part a trim DAC for setting bias points, margining supply rails, or calibrating sensor offsets in mixed-signal systems.
Supply flexibility and accuracy
The INL is ±1 LSB maximum and DNL is ±0.5 LSB maximum, guaranteeing monotonic output across all codes without missing steps. The differential output is not used — the part outputs a single-ended current on each channel.
