12-bit DAC with 4 µs settling in a hermetic CDIP-24
The ADDAC80-CBI-I is a 12-bit digital-to-analog converter with a current-buffered output, settling to within ±0.5 LSB in 4 µs. It accepts parallel data and provides a current output that can be converted to voltage with an external op-amp. Housed in a 24-pin ceramic DIP (0.600-inch body width), it is a through-hole part suited for legacy or high-reliability board builds where a hermetic package is preferred.
Supply rails and reference flexibility
The part operates on analog and digital supplies of ±11.4 V to ±16.5 V, and accepts either an external or internal voltage reference. The dual-supply requirement means the board must provide both positive and negative rails — a single-supply system will not work without a DC-DC converter.
Active lifecycle and compliance status
Note that the part is RoHS non-compliant. For builds requiring RoHS exemption or lead-free assembly, a different DAC variant or a secondary source such as the AD667AD (also through-hole, 12-bit, 4 µs settling) should be evaluated. The AD667AD is a voltage-output device, so the output stage differs, but the digital interface and resolution match.
Sourcing and supply posture
As an active part with no single-source restriction, the ADDAC80-CBI-I can be quoted to order through independent distribution. For BOM risk management, the AD667AD offers a drop-in functional alternative in the same package and pinout, though its output is voltage-buffered rather than current-buffered. Verify the downstream circuit's input impedance before substituting.
