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

• Low Power Consumption

• 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.
