MP7529B

MP7529B 5 V CMOS Dual Buffered Multiplying 8-Bit Digital-to-Analog Converter FEATURES Very Low Total Harmonic Distortion Low Glitch Energy Fast Settling Time Four Quadrant Multiplication On-Chip Latches for Both DACs 4.5 V to 5.5 V Operation Low Power Consumption TTL/5V CMOS Compatible Latch-Up Free 15 V Operation: MP7529A BENEFITS Quiet Operation in Audio Applications Easy Interface to Microprocessors GENERAL DESCRIPTION The MP7529B is a dual 8-bit Digital-to-Analog Converter featuring excellent DAC to DAC matching, tracking and specifically optimized for applications requiring low total harmonic distortion. The MP7529B is manufactured using advanced thin film resistors on a double metal CMOS process. The MP7529B incorporates a unique bit decoding technique yielding lower glitch energy, higher speed and excellent accuracy over temperature and time. Data is transferred to either of the two D/A Converter latches via a common 8-bit TTL/5 V CMOS compatible input port. The control input DAC A/DAC B determines which D/A is to be loaded. The device operates from a 4.5 V to 5.5 V power supply, and is TTL-compatible over this range. Power dissipation is only 10 mW. Both DACs offer excellent four quadrant multiplication characteristics, and include separate reference inputs and feedback resistors. An improved latch-up resistant design eliminates the need for external protective Schottky diodes in most applications. SIMPLIFIED BLOCK AND TIMING DIAGRAM www.Da...
