GENERAL DESCRIPTION The DAC8412/DAC8413 are quad, 12-bit voltage output DACs with readback capability. Built using a complementary BiCMOS process, these monolithic DACs offer the user very high package density. FEATURES +5 V to ±15 V operation Unipolar or bipolar operation True voltage output Double-buffered inputs Reset to minimum (DAC8413) or center scale (DAC8412) Fast bus access time Readback APPLICATIONS Automatic test equipment Digitally controlled calibration Servo controls Process control equipment
Product Details The AD7528 is a monolithic dual 8-bit digital/analog converter featuring excellent DAC-to-DAC matching. It is available in skinny 0.3" wide 20-pin DIP"s and in 20-terminal surface mount packages. Separate on-chip latches are provided for each DAC to allow easy microprocessor interface. Data is transferred into either of the two DAC data latches via a common 8-bit TTL/CMOS compatible input port. Control input DAC A/DAC B determines which DAC is to be loaded. The AD7528"s load cycle is similar to the write cycle of a random access memory and the device is bus compatible with most 8-bit microprocessors, including 6800, 8080, 8085, Z80. The device operates from a +5V to +15V power supply, dissipating only 20mW of power. Both DAC"s offer excellent four quadrant multiplication characteristics with a seperate reference input and feedback resistor for each DAC.
