® PCM1700U PCM1700P Dual 18-Bit Monolithic Audio DIGITAL-TO-ANALOG CONVERTER FEATURES q DUAL 18-BIT LOW-POWER MONOLITHIC AUDIO D/A CONVERTER q VERY LOW MAX THD+N: –92dB Without External Adjust q CO-PHASE, LOW-GLITCH ±3V OR ±670µA AUDIO OUTPUTS q CAPABLE OF 16X PER CHANNEL OVERSAMPLING RATE q COMPLETE WITH INTERNAL REFERENCE q SERIAL INPUT FORMAT 100% COMPATIBLE WITH INDUSTRY STD PCM56P q RUNS ON ±5V SUPPLIES AND DISSIPATES 300mW MAX q COMPACT 28-PIN PLASTIC DIP OR SOIC DESCRIPTION The PCM1700 is a low cost, high-performance, dual 18-bit digital-to-analog converter. The PCM1700 features low glitch, co-phase current and voltage outputs and only requires ±5V supplies. The PCM1700 comes complete with an internal reference and optional MSB adjustability for even greater THD performance. Total power dissipation is less than 400mW max. Low maximum Total Harmonic Distortion + Noise (–92dB max; PCM1700P-K) is 100% tested. The very fast PCM1700 is also capable of 16X oversampling rates on both channels simultaneously, providing freedom in output filter selection. The PCM1700 comes in space-saving 28-pin plastic DIP and SOIC packages. PCM1700 accepts a serial data input format that is compatible with other BurrBrown PCM products such as the industry standard PCM56P.
