8-bit multiplying DAC in a hermetic ceramic package
The 5962-87700022A is an 8-bit multiplying DAC from Analog Devices, built on a classic R-2R ladder architecture with current-unbuffered output. It settles to within ±0.25 LSB (max) in 250 ns, which means a full-scale step update every 4 µs at 8-bit resolution gives the downstream amplifier time to settle before the next conversion. The 20-lead ceramic LCCC (20-LCCC, 9x9 mm) package provides a hermetic seal, and the -55°C to 125°C operating range qualifies it for avionics, satellite, and downhole instrumentation where commercial plastic packages would delaminate or leak.
Supply rails and interface — one voltage, no split rail hassle
Both the analog and digital supplies share a single 5V to 15V range, so a single 5V or 12V rail powers the entire DAC. The parallel data interface writes all 8 bits in one bus cycle — no serial shift-out latency, which matters when the DAC is fed from a legacy DSP or an FPGA with a wide parallel bus. Because it is a multiplying DAC, the reference input accepts AC signals; the output is the product of the digital code and the reference voltage. This makes it useful for digitally controlled attenuators or waveform generators where the reference is a sine wave, not just a DC level.
Sourcing and lifecycle — active, no EOL pressure
For a military-temperature ceramic DAC that has been in production for decades, active means the die and package supply chain are still running. The part is RoHS non-compliant per the current listing. This is typical for ceramic hermetic packages that use tin-lead solder on the leads for reliability in temperature cycling. Buyers in RoHS-exempt categories (aerospace, military, medical implant) can proceed; commercial RoHS-mandated builds should check their exemption policy.
