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.
