Abstract
Apparatus, system, and method for detecting AC-coupled electrical loads of a set of digital-to-analog converters are described. In one embodiment, a processing apparatus includes a digital-to-analog converter. The processing apparatus also includes a pulse generation module connected to the digital-to-analog converter, and the pulse generation module is configured to direct the digital-to-analog converter to transmit a pulse of electrical energy. The processing apparatus further includes a load detection module connected to the digital-to-analog converter, and the load detection module is configured to determine a connection status of the digital-to-analog converter based on a degree to which the pulse of electrical energy is reflected during a transient response time period.
