Product Summary
The AK4702EQ is a 2ch DAC with AV SCART switch offers the ideal features for digital set-top-box systems. Using AKM’s multi-bit architecture for its modulator, the AK4702EQ delivers a wide dynamic range while preserving linearity for improved THD+N performance. The AK4702EQ 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 AK4702EQ also including the audio switches and volumes designed primarily for digital set-top-box systems. The AK4702EQ is offered in a space saving 48-pin LQFP package.
