AK4380

100dB 24Bit 96kHz 2ch DAC

GENERAL DESCRIPTION

The AK4380 offers the perfect mix for cost and performance based audio systems. Using AKM's multi bit

architecture for its modulator the AK4380 delivers a wide dynamic range while preserving linearity for

improved THD+N performance. The AK4380 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 24 Bit word length and 96kHz sampling rate make this part ideal for a wide range of applications

including DVD and AC-3 systems. The AK4380 is offered in a space saving 16pin TSSOP package.

FEATURES

o Sampling Rates Ranging from 8kHz to 96kHz

o 128x Oversampling (Normal speed mode)

o 64x Oversampling (Double speed mode)

o 24Bit 8x FIR Digital Filter

o 2nd order Analog LPF

o On chip Buffer with Single End Output
