A 199 KB PDF covering the AD7528, a dual 8-bit multiplying digital-to-analogue converter from Analog Devices with a shared data bus and a select line for each DAC. The datasheet provides pinout, write timing, reference inputs for both channels and typical output circuits. On audio, control and test equipment boards it lets a technician check that both reference inputs are present, the write and select signals reach the chip, and the output op amps behave. Verify package and grade suffix printed on the chip before substituting.
