The D/A Converter (or DA Converter) component is a simple digital to analog converter with an input signal width of $N$ bits.

The input signal is an $N$-vector of type Logic.

The output voltage of value $y$ is generated by an ideal voltage source. The output changes when the trigger signal $\mathrm{trig}$ of type Logic changes to 1 (forced or weak).

The first bit in the input vector, $x_1$, is the least significant.

Dynamic behavior is not modeled; the output changes instantaneously when the trigger signal rises.

$y\=v_p-v_n\=V_{\mathrm{lsb}}\sum _{i\=1}^N{x}_i{2}^{i-1}$

$V_{\mathrm{lsb}}\=\frac{V_{\mathrm{ref}}}{2^N-1}$

$i_p\+i_n\=0$
