The LC75010W is a 1-chip DSP that is ideal for car stereos as it incorporates major required functions 
such as A/D, D/A, and a DSP core. This is a custom IC that incorporates DSP software based on the user 
specifications. 

The LC83200W is an IC that integrates the functions required for Dolby Headphone on one chip. It 
generates a Dolby Headphone audio output signal from either a 5.1-channel or 2-channel audio input.  
The LC83200W provides DH1, DH2, DH3, and Stereo Mixdown as room modes and can be used in all 
products that have a headphone pin.
