GENERAL DESCRIPTION

AK5367A is a high-performance 24-bit, 96kHz sampling ADC for consumer audio and digital recording applications. The AK5367A uses an Enhanced Dual-Bit modulator architecture, this analog-to-digital converter has an impressive dynamic range of 102dB with high level integration. The AK5367A has a 4-channel stereo input selector, an input Programmable Gain Amplifier with resistance. All this integration with high-performance makes the AK5367A well suited for CD and DVD recording systems. The integrated charge pump circuit can generate the negative power supply and remove the output coupling capacitor.
