Product Overview
The DAC7631 is a 16-bit serial-input voltage-output digital-to-analog converter from Texas Instruments. It provides monotonic operation over the specified temperature range and accepts a +5 V single supply or dual +5 V and -5 V supplies. The output range is determined by the voltage references applied to VREFH and VREFL, enabling unipolar 0 V to VREFH or bipolar VREFL-to-VREFH operation. The selectable reset function, via the RESETSEL pin, allows the DAC output to power up to mid-scale (8000h) or zero-scale (0000h). The device includes a VOUT SENSE pin that can close the feedback loop at the load for improved accuracy. Packaged in a 20-pin SSOP, the DAC7631 is suitable for precision analog output modules, industrial control systems, and automated test equipment where 16-bit resolution and fast settling are required.

Procurement Notes
When requesting a quote for DAC7631, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
