16-Bit Sigma-Delta CODEC (ADC & DAC) with headset, handset and 400mW Speaker Amplifier, Dongbu 0.11um
The AR34P2A specifies a mass-production proven, low power mono audio CODEC IP for multimedia audio / voice phone system. The IP employs multi-bit sigma delta architecture. It contains on-chip 400mW speaker amplifier to drive 4ohm speaker load externally, and built-in bandgap reference, on-chip regulators for better noise immunity. The IP is fabricated in Dongbu 110nm process and can be ported to other nodes.
