The PCM1702 is a precision 20-bit digital-to-analog
converter with ultra-low distortion (–96dB typ with a
full scale output). Incorporated into the PCM1702 is
an advanced sign magnitude architecture that elimi-
nates unwanted glitches and other nonlinearities around
bipolar zero. The PCM1702 also features a very low
noise (120dB typ SNR: A-weighted method) and fast
settling current output (200ns typ, 1.2mA step) which
is capable of 16
X
oversampling rates.
Applications include very low distortion frequency
synthesis and high-end consumer and professional
digital audio applications.
