Product Summary

The DF1704E is a high performance, stereo, 8X oversampling digital interpolation filter designed for high-end consumer and professional audio applications. The DF1704E supports 24-bit, 96kHz operation and features user-programmable functions, including selectable filter response, de-emphasis, attenuation and input/output data formats. The DF1704E is the ideal companion for PCM1704 24-bit audio digital-to-analog converter of the Burr-Brown.
