AK4344
3V 96kHz 24-Bit 2ch DAC with 1Vrms Output
|
The AK4344 is a 24bit low voltage & low power stereo DAC. The AK4344 uses the Advanced Multi-Bit DS 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.
