AD7547BQ

Discontinued by Analog Devices, the AD7547BQ is a dual 12-bit multiplying digital-to-analog converter (DAC) built on the company’s LC²MOS (linear-compatible CMOS) process. It houses two complete 12-bit DAC cores with individual reference inputs and parallel input latches, supporting simultaneous or independent channel updates for precision voltage-output configurations. The hermetic ceramic DIP (CDIP) package ensures robust environmental resilience, making the part a reliable choice for extended-temperature and high-reliability installations. Typical performance characteristics include low glitch energy and high integral linearity, enabling clean analog signals in closed-loop control, waveform generation, and critical signal-chain roles.

The AD7547BQ has been officially retired from production and is no longer manufactured. For legacy platforms where requalification costs and recertification timelines make board-level redesign impractical, ZZX Electronics supplies sustaining stock with full date-code traceability. This end-of-life DAC remains viable for maintaining deployed systems in defense fire-control, avionics test equipment, industrial process controllers, and precision instrumentation—applications where a drop-in replacement preserves the validated performance envelope and avoids a complete system re-spin. By sourcing authentic, date-code-verified inventory, program managers and design engineers can extend the operating life of mature platforms while adhering to configuration-control requirements.
