MP7529B  
5 V CMOS  
Dual Buffered Multiplying 8-Bit  
Digital-to-Analog Converter  
FEATURES  
BENEFITS  
Very Low Total Harmonic Distortion  
Low Glitch Energy  
Quiet Operation in Audio Applications  
Easy Interface to Microprocessors  
Fast Settling Time  
Four Quadrant Multiplication  
On-Chip Latches for Both DACs  
4.5 V to 5.5 V Operation

TTL/5V CMOS Compatible  
Latch-Up Free  
15 V Operation: MP7529A  
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.  
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.  
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.
