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.
