DF1706E Datasheet PDF - TI

●DESCRIPTION

●The DF1706 is a high performance, stereo, 8X oversampling digital interpolation filter designed for high-end consumer and professional audio applications. 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-Analog (D/A) converter. This combination allows for the construction of very high-performance audio systems and components.
