Analog Devices AD7541 datasheet, a 234 KB PDF for a 12-bit multiplying digital-to-analogue converter with parallel data inputs and current outputs. Inside are the pinout, reference and feedback connections, accuracy grades and typical circuits with an external op amp. Technicians use it to trace the reference voltage and output amplifier on boards where the analogue output is wrong, noisy or missing, and to check that logic inputs reach valid levels. Compare the exact suffix on the part with the ordering data, since accuracy grades differ.
