AK5367
96kHz 24-Bit ΔΣ ADC with 0V Bias Selector
GENERAL DESCRIPTION
AK5367 is a high-performance 24-bit, 96kHz sampling ADC for consumer audio and digital recording
applications. The AK5367 uses an Enhanced Dual-Bit modulator architecture, this analog-to-digital
converter has an impressive dynamic range of 102dB with a high level of integration. The AK5367 has a
4-channel stereo input selector, an input Programmable Gain Amplifier with resistance. All this integration
with high-performance makes the AK5367 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.
