Description
• Two-Channel AD/DA Converters and Their Respective
Digital Filters for Decimation and Oversampling Into a
Single Chip
The HI2555, CXD2555 is a 1-bit stereo AD/DA converter
featuring a 2nd-order DA system noise shaper. This LSI has
also built-in digital filters and provides good cost performance.
