Product Summary

The ad7528lr is a monolithic dual 8-bit digital/analog converter featuring excellent DAC-to-DAC matching. It is available in skinny 0.3" wide 20-lead DIPs and in 20-lead surface mount packages. Separate on-chip latches are provided for each DAC to allow easy microprocessor interface. The ad7528lr’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 ad7528lr operates from a +5 V to +15 V power supply, dissipating only 20 mW of power. Both DACs offer excellent four quadrant multiplication characteristics with a separate reference input and feedback resistor for each DAC.
