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

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.
