AK4430  
192kHz 24-Bit Stereo ΔΣ DAC with 2Vrms Output  
GENERAL DESCRIPTION  
The AK4430 is 3.3V 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 AK4430 delivers a wide dynamic range while preserving  
linearity for improved THD+N performance. The AK4430 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 portable A/V players, set-top boxes, and digital televisions. The AK4430 is offered in  
a space saving 16pin TSSOP package.
