AD7846AP

Now discontinued and no longer manufactured, the AD7846AP from Analog Devices is a 16-bit voltage-output digital-to-analog converter that combines a precision multiplying DAC with an on-chip output amplifier in a 28-lead PLCC package. Operating from dual supplies and an external voltage reference, the device produces a bipolar ±10 V output swing capable of driving resistive and capacitive loads directly, eliminating external buffer amplifiers in many analog output stages. Its parallel data interface with double-buffered input latches provides seamless connection to 16-bit microcontrollers and DSPs, while the voltage-mode architecture supports monotonic low-glitch updates over the full industrial temperature range.

The AD7846AP was widely deployed in industrial automation, process control, automatic test equipment, avionics, and closed-loop servo systems that depend on high-resolution bipolar analog drive. Since Analog Devices has officially ended production, sourcing genuine legacy stock with full date‑code and lot traceability becomes essential for maintaining long‑field‑life equipment. ZZX Electronics supplies traceable inventory of this end‑of‑life DAC, enabling repair depots and MRO operations to support deployed platforms without a board respin, requalification cycle, or firmware revalidation—keeping high‑reliability industrial, aerospace, and defense systems operational for decades while avoiding the cost and schedule impact of a full redesign.
