Description

The DF1706 is a high performance, stereo, 8X oversampling digital interpolation filter designed for high-end consumer and professional audio applica-tions. The DF1706 supports 24-bit, 192kHz operation and features user-programmable functions, including selectable filter response, de-emphasis, attenuation,and input/output data formats.
The DF1706 is the ideal companion for Texas Instruments's PCM1704 24-bit audio Digital-to-Ana-log (D/A) converter.This combination allows for the construction of very high-performance audio systems and components.
