PCM4220 High-Performance 24-Bit Sampling Analog-to-Digital Converter
PCM4220 描述
The PCM4220 is a high-performance, two-channel analog-to-digital (A/D) converter designed for use in professional audio applications. Offering outstanding dynamic performance, the PCM4220 provides 24-bit linear PCM output data, with support for output word length reduction to 20-, 18-, or 16-bits. The PCM4220 includes three sampling modes, supporting output sampling rates from 8kHz to 216kHz. The PCM4220 is ideal for a variety of digital audio recording and processing applications.
A linear phase digital decimation filtering engine supports Classic and Low Group Delay filter responses, allowing optimization for either studio or live sound applications. In addition, digital high-pass filtering is provided for DC offset removal..
