GENERAL DESCRIPTION

The AK4341 is the 24bit DAC with 2Vrms line output for cost and performance based audio systems. Using AKMs 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.
