GENERAL DESCRIPTION
The AK4340 offers the ideal features for consumer systems that require a 2Vrms audio output. Using AKM's multi bit architecture for its modulator the AK4340 delivers a wide dynamic range while preserving linearity for improved THD+N performance. The AK4340 integrates the Switched Capacitor Filter (SCF) 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 including Set-top-box, DVD-Audio. The AK4340 is offered in a space saving 16pin TSSOP package.
