Audio DAC with an Integrated 2 Vrms Output Buffer – Analog Circuits
AKM Semiconductor’s AK4341 stereo 24-bit, 192 kHz audio D/A converter features an integrated 2 Vrms output buffer and is suited for consumer applications including digital televisions, set-top boxes, A/V receivers, and portable audio docking stations. The DAC generates a 2 Vrms output swing with an integrated output buffer that is powered by a separate power supply ranging from +8.55V to +12.6V, while the core DAC operates from a +3.3V nominal supply. Applications do not need an external buffer. The DAC section achieves 100 dB dynamic range and -86 dB THD+N.
