Incorporated into the PCM1702 is an advanced sign magnitude architecture that eliminates unwanted glitches and other nonlinearities around bipolar zero. The PCM1702 also Features a very low noise (120d B typ SNR: A-weighted method) and fast settling current output (200ns typ, 1.2m A step) which is capable of 16X oversampling rates. Applications include very low distortion frequency synthesis and high-end consumer and professional digital audio applications.
