AK4345
100dB 96kHz 24-Bit Stereo 3.3V ÎΣ DAC with DIT
GENERAL DESCRIPTION
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 ÎΣ 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.
