Product Summary
The ak4705vq-l is a 2ch 24bit DAC. The ak4705vq-l offers the ideal features for digital set-top-box systems. Using AKMs multi-bit architecture for its modulator, the ak4705vq-l delivers a wide dynamic range while preserving linearity for improved THD+N performance. The ak4705vq-l integrates a combination of SCF and CTF filters, removing the need for high cost external filters and increasing performance for systems with excessive clock jitter. The ak4705vq-l also including the audio switches, volumes, video switches, video filters, etc. designed primarily for digital set-top-box systems. The ak4705vq-l is offered in a space saving 48-pin LQFP package.
