AK4341
192kHz 24-Bit Stereo
ΔΣ
DAC with 2Vrms Output
GENERAL DESCRIPTION
The AK4341 is the 24bit DAC with 2Vrms line output for cost and performance based audio systems.
Using AKM's multi bit architecture for its modulator, the AK4341 delivers a wide dynamic range while
preserving linearity for improved THD+N performance. The AK4341 integrates a combination of SCF and
CTF 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 applications such as digital STB, DVD,
AC-3 receiver system, etc. The AK4341 is offered in a space saving 16pin TSSOP package.
