A digital-to-analog-converter is an electronic circuit or integrated chip that reconstructs a continuous analog voltage waveform from a stream of discrete digital codes. Its parameters are: (1) resolution — the number of bits per sample, determining quantization precision (8-bit to 32-bit commonly); (2) sampling rate — the maximum rate at which new analog values are produced, measured in samples per second; (3) output format — unbuffered voltage, buffered voltage, or current output depending on downstream requirements; (4) reconstruction filter — analog low-pass filter removing spectral images above the Nyquist frequency; (5) reference voltage — the full-scale analog range mapped from the digital code range. Persistence mechanism: manufactured through semiconductor fabrication (CMOS, BiCMOS, or bipolar processes), distributed through electronics supply chains, maintained through firmware updates (for programmable DACs) or physical replacement.

Definition
Why it is in scope
An electronic circuit or integrated chip that reconstructs a continuous analog voltage waveform from a stream of discrete digital codes, human-made through precision analog design and silicon fabrication, built to persist as the standard bridge between digital sources and analog amplification in audio, video, and control practice.

Law 9 specific-to-general, nearest kind: DAC's accepted carve is 'an electronic circuit or integrated chip that reconstructs a continuous analog voltage waveform from a stream of discrete digital codes' — input form: discrete digital codes, output form: continuous analog voltage, transformation law: quantization ladder plus reconstruction filter. That is precisely converter's carve (domain transformation preserving information content). No more specific kind node exists, so converter is the nearest accepted kind.

A DAC's sole purpose is to transform one kind of signal (digital) into another (analog). Remove signal from the domain and the DAC has nothing to operate on — it stops functioning entirely. This is object-level dependency: signal is not a meta-level condition shared by all concepts, but the specific domain in which a DAC operates. The removal test passes cleanly.
