Analog Devices datasheet for the AD7845, a 12-bit multiplying digital-to-analogue converter with an on-chip output amplifier, supplied as a 255 KB PDF. The document gives the pin configuration, digital interface timing, reference input range and output specifications. In instrument and industrial controller repair it helps trace the reference voltage, data lines and output stage of a DAC that produces a wrong or stuck level. Confirm the package and grade suffix printed on the chip, as accuracy and temperature range vary between versions.
