GENERAL DESCRIPTION

The AK2301A is a single channel PCM CODEC for speech processing 8kHz sampling PCM data by DSP. The AK2301A interfaces with 14bit linear data (16bit format).

It includes Band limiting filter, A/D and D/A converter, and universal op-amps for construction of the output filter. All functions are provided in small 24pin VSOP package and it is good for reducing the mounting space.
