Product Overview
The DAC8831 is a Texas Instruments 16-bit voltage-output DAC for Signal_Chain designs requiring precision digital-to-analog conversion. It operates from a 2.7 to 5.5 V supply and has specified performance across -40 to +85 °C. The output range is 0 to +VREF in unipolar operation, with -VREF to +VREF bipolar operation available for DAC8831 when used with an external buffer.
Static accuracy depends on grade, with linearity error maximums of ±1 LSB, ±2 LSB, or ±4 LSB for listed DAC8831 grades. Differential linearity error is specified at typical ±0.5 LSB and maximum ±1 LSB across all grades. Dynamic output specifications include 1 µs settling time to 1/2 LSB with CL = 10 pF and 25 V/µs slew rate.
The device uses an SPI-compatible serial interface up to 50 MHz, with 20 ns minimum SCLK period and 10 ns minimum SCLK high or low time. DAC8831 package options listed are SO-14 (D) and QFN-14 (RGY), with QFN-14 θJA of 54.9 °C/W and SO-14 θJA of 66.6 °C/W.

Procurement Notes
When requesting a quote for DAC8831, 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.
