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.
