eng.DAC-settling-time Calculator
Calculates DAC settling time to within a specified accuracy from slew rate, bandwidth, and target voltage step. DAC settling time must be less than the sample period in signal reconstruction systems — glitch energy during code transitions can corrupt the output.
Inputs
C Load Pf
Ability to store electric charge (F). Capacitors charge quickly and release energy fast. Common values: pF to μF.
R Output Ohm
Opposition to current flow (Ω). V = IR. Resistors in series add; in parallel their reciprocals add.
Vswing V
Electric potential difference (V). Drives current through a circuit. Household: 120 V (US) or 230 V (EU/UK).
Accuracy Pct
Reference formula or conversion factor shown for context.
Results
RC time constant τ (ns)
Time for the capacitor (or inductor) to reach 63.2% of its final value. τ = RC. After 5 time constants (~99.3%), the circuit is effectively at steady state.
settling time to accuracy (ns)
The fraction of predictions or measurements that are correct. High accuracy is only meaningful when the class distribution is balanced.
bandwidth BW (MHz)
The computed width.
minimum slew rate needed (V/μs)
The smallest value in the dataset or feasible range.
t_settle = -τ·ln(accuracy)
The fraction of predictions or measurements that are correct. High accuracy is only meaningful when the class distribution is balanced.
for 16-bit DAC accuracy
The fraction of predictions or measurements that are correct. High accuracy is only meaningful when the class distribution is balanced.
