AK4424  
192kHz 24-Bit Stereo ΔΣ DAC with 2Vrms Output  
GENERAL DESCRIPTION  
The AK4424 is a 5V 24-bit stereo DAC with an integrated 2Vrms output buffer. A charge pump in the  
buffer develops an internal negative power supply rail that enables a ground-referenced 2Vrms output.  
Using AKM’s multi bit modulator architecture, the AK4424 delivers a wide dynamic range while preserving  
linearity for improved THD+N performance. The AK4424 integrates a combination of switched-capacitor  
and continuous-time filters, increasing performance for systems with excessive clock jitter. The 24-bit  
word length and 192kHz sampling rate make this part ideal for a wide range of consumer audio  
applications, such as DVD, AV receiver system and set-top boxes. The AK4424 is offered in a space  
saving 16pin TSSOP package.
