Overview
® 49% FPO PCM1702P PCM1702U BiCMOS Advanced Sign Magnitude 20-Bit DIGITAL-TO-ANALOG CONVERTER FEATURES q ULTRA LOW –96dB max THD+N (No External Adjustment Required) q q q q q NEAR-IDEAL LOW LEVEL OPERATION GLITCH-FREE OUTPUT 120dB SNR TYP (A-Weight Method) INDUSTRY STD SERIAL INPUT FORMAT FAST (200ns) CURRENT OUTPUT (±1.
2mA) DESCRIPTION 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 eliminates 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 16X oversampling rates.
Applications include very low distortion frequency synthesis and high-end consumer and professional digital audio applications.
