DESCRIPTION

The PCM1716 is designed for Mid to High grade

Digital Audio applications which achieve 96kHz sam-

pling rates with 24-bit audio data. PCM1716 uses a

newly developed, enhanced multi-level delta-sigma

modulator architecture that improves audio dynamic

performance and reduces jitter sensitivity in actual

applications.

The internal digital filter operates at 8x over sampling

at a 96kHz sampling rate, with two kinds of roll-off

performances that can be selected: sharp roll-off, or

slow roll-off, as required for specific applications.

PCM1716 is suitable for Mid to High grade audio

applications such as CD, DVD-Audio, and Music

Instruments, since the device has superior audio

dynamic performance, 24-bit resolution and 96kHz

sampling.
