描述 Description

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.FEATURES
●ULTRA LOW –96dB max THD+N (No External Adjustment Required)
●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)
●CAPABLE OF 16X OVERSAMPLING
●COMPLETE WITH REFERENCE
●LOW POWER (150mW typ)
