[AK4344]
AK4344
100dB 96kHz 24-Bit Stereo 3.3V ÎΣ DAC
GENERAL DESCRIPTION
The AK4344 is a 24bit low voltage & low power stereo. The AK4344 uses the Advanced Multi-Bit ÎΣ
architecture, which achieves DR=100dB at 3.3V operation. The AK4344 integrates a combination of SCF
and CTF filters increasing performance for systems with excessive clock jitter. The output voltage level
can be set as high as 1Vrms. The AK4344 is offered in a space saving 16pin TSSOP package.
