IBM 65nm 24bit Sigma-Delta DAC
Overview
The I65GV25_DAC_01 specifies the design of a high-performance 24-bit stereo Audio DAC for portable digital audio systems. The DAC within the specification uses sigma-delta technique, and the output analog signals including stereo output are single-ended,. The internal stereo headphone amplifier is capable of driving 16Ω load.
