The Analog Devices DAC8412FPCZ is a radiation-hardened, quad 12-bit digital-to-analog converter (DAC) ASIC. It features buffered voltage outputs and readback capability via a parallel interface. The device operates from supplies ranging from +5 V to ±15 V with power dissipation under 330 mW at ±15 V. Key electrical specifications include integral nonlinearity of ±1 LSB, differential nonlinearity of -1 LSB, and a settling time of 10 μs to 0.01%. It utilizes a complementary BiCMOS process for high package density.
Verify the specific grade (E or F) and package type (PLCC-28) against the MIL-STD-883 requirements. Confirm that the ordering suffix matches the required radiation-hardened specification and temperature range (-55°C to +125°C). Ensure compatibility with existing board layouts for the 28-lead PLCC footprint.
Select this component when a quad 12-bit DAC with parallel access and readback is required in harsh environments. The DAC8412 variant resets to midscale, which is advantageous for bipolar reference configurations requiring a zero-volt output upon reset. Consider the 10 μs settling time and ±1 LSB INL for precision applications.
This part number corresponds to the DAC8412 series manufactured under Standard Military Drawing 5962-9176401MXA. It is distinct from the commercial DAC8413, which resets to minimum scale (zero code). Both share identical functional blocks but differ in their default reset state behavior.
Public confirmed substitute part numbers are not available in the provided documentation.
