GENERAL DESCRIPTION
The AK4705 offers the ideal features for digital set-top-box systems. Using AKM's multi-bit architecture
for its modulator, the AK4705 delivers a wide dynamic range while preserving linearity for improved
THD+N performance. The AK4705 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
AK4705 also including the audio switches, volumes, video switches, video filters, etc. designed primarily
for digital set-top-box systems. The AK4705 is offered in a space saving 48-pin LQFP package.
