DIGITAL AUDIO DACs
AK4345
3V 96kHz 24-Bit 2ch DAC with DIT and 1Vrms Output
The AK4345 is a 24bit low voltage and low power stereo DAC with an integrated Digital Audio Interface Transmitter. The AK4345 uses an Advanced Multi-Bit DS architecture, which achieves 100dB dynamic range at 3.3V operation. The AK4345 integrates both switched-capacitor and continuous time filters, enabling performance for systems that have excessive clock jitter. The output voltage level can be set as high as 1Vrms. The AK4345 is offered in a space saving 16pin TSSOP package.
