DESCRIPTION
The DF1704 is a high performance, stereo, 8X
oversampling digital interpolation filter designed for
high-end consumer and professional audio applica-
tions. The DF1704 supports 24-bit, 96kHz operation
and features user-programmable functions, including
selectable filter response, de-emphasis, attenuation,
and input/output data formats.
The DF1704 is the ideal companion for Burr-Brown’s
PCM1704 24-bit audio digital-to-analog converter.
This combination allows for construction of very high
performance audio systems and components.
