IBM 65nm 24-bit Stereo Sigma-Delta ADC
Overview
The I65GV25_ADC_01 specifies the design of a high-performance 24-bit stereo Audio ADC for portable digital audio systems. The ADC within the specification uses sigma-delta technique, and its input analog signals are single-ended, stereo input(Line in or FM in). Mono microphone input is also supported.
