Product Summary
The W51300-701 is a voice recorder IC. The W51300-701 contains A/D and D/A converters to digitize and reproduce voice signals. An antialias/smoothing filter, AGC circuit, MIC preamplifier, and speaker power amplifier are used to smooth the input voice and set the output voice to a certain volume while minimizing the number of extra components needed. The recording time depends on the size of the external memory.
