The output signal is connected to an amplifier, headphones, or external device using standard interconnects, such as a TRS phone connector or an RCA connector. Most sound cards use a digital-to-analog converter (DAC), which converts recorded or generated digital data into an analog format. Often still referred to as a "sound card".Ĭlose-up of a sound card PCB, showing electrolytic capacitors, SMT capacitors and resistors, and a YAC512 two-channel 16-bit DAC.
