Datasheet for the AD7523 from Analog Devices, an 8-bit multiplying DAC with current outputs, provided as a 178 KB PDF. It includes the pin layout, reference input range, feedback resistor connection, accuracy grades and example circuits using an external op amp. In repairs of older controllers and instruments, it serves to confirm the reference voltage, check that the eight data inputs switch to valid logic levels and trace the output amplifier. Compare the marking and package on the board against the datasheet ordering information first.
