About this component
Compact educational four-bit DAC with unipolar straight-binary inputs (D0 LSB, D3 MSB). Its ideal transfer is VOUT=VREF×code/16, so one LSB is VREF/16 and code 1111 is one LSB below VREF; the configurable series output resistance exposes loading and RC reconstruction behavior.
Parameters
Conversion
1 parameter
VREF
Reference voltage
Positive reference used by VOUT=ReferenceVoltage multiplied by code divided by 16.
5 V
Logic levels
1 parameter
VTH
Input threshold
Voltage at or above which each code input is interpreted as logic high.
2.5 V
Output
1 parameter
ROUT
Output resistance
Series resistance between the ideal code voltage and VOUT; it exposes DAC loading and reconstruction-filter behavior.
