DAC A/DAC B
FEATURES
GENERAL DESCRIPTION
featuring excellent DAC-to-DAC matching, tracking and
specifically optimized for applications requiring low total
harmonic distortion. The MP7529A is manufactured using
advanced thin film resistors on a double metal CMOS process.
The MP7529A incorporates a unique decoding technique
yielding lower glitch energy, higher speed and excellent
accuracy over temperature and time.
SIMPLIFIED BLOCK AND TIMING DIAGRAM

via a common 8-bit TTL/5 V CMOS compatible input port. The
control input DAC A/DAC B determines which DAC is to be
loaded.
power supply, and is TTL-compatible over this range. Power
dissipation is only 20 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.
BENEFITS
Data is transferred to either of the two D/A Converter latches
