AK4348
3.3V 192kHz 24-Bit 8-Channel DAC
GENERAL DESCRIPTION
The AK4348 is an 8-channel 24bit DAC operating off of a single +3.3V power supply. The outputs are
single-ended, and it samples at rates from 8kHz to 192kHz. It uses AKM’s advanced multi-bit architecture
for the modulator to achieve a wide dynamic range while preserving linearity for improved THD+N
performance. The output circuit includes a switched-cap filter and a second-order analog low pass filter,
minimizing the need for external filtering.
