Description

The AK4346 is an 6-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.
