Product details

16-bit precision DAC in a small 8-VSSOP package

It uses a String DAC architecture with an external reference and delivers a buffered voltage output. The device settles to within 1 LSB in 10 µs, making it suitable for precision control loops, waveform generation, and sensor calibration where update rates up to 100 kHz are needed.

Package and mounting

The integral nonlinearity (INL) is ±3 LSB maximum, which at 16 bits corresponds to roughly ±46 ppm of full-scale. That is the absolute-accuracy spec: if you command mid-scale, the output lands within that window of the ideal transfer function. The differential nonlinearity (DNL) is ±0.25 LSB — well inside the ±0.5 LSB boundary that guarantees monotonicity. No missing codes, so a closed-loop PID controller or a precision setpoint generator will not see the output step backward when the digital code increments. For a 16-bit DAC, this DNL spec is tight enough that you can run open-loop trimming without worrying about non-monotonic jumps.

Supply and interface — single-rail simplicity

No separate AVDD/DVDD sequencing or split-plane headache. The SPI/DSP interface accepts standard 3.3 V logic levels directly — no level shifter needed when the host MCU runs at 3.3 V. The 8-VSSOP package (3.00 mm width) fits tight mixed-signal layouts, and the buffered output can drive a few milliamps into a sample-and-hold or ADC driver input without an external op-amp.

Frequently asked questions

Is DAC8550IBDGKT compatible with 3.3 V SPI?

Yes. No level translator is required when the host MCU runs at 3.3 V.

Is DAC8550IBDGKT RoHS compliant?

Yes, it is ROHS3 compliant, meeting European and most global environmental requirements without exemptions.

What is the replacement or equivalent for DAC8550IBDGKT?

The DAC8550IBDGKT is an active product with no official replacement. The closest functional peer in the same family is the DAC7750IPWP, but that is a 12-bit current-output DAC with a different supply voltage (10 V) and settling time (25 µs) — not a pin-to-pin or function-to-function substitute. For a 16-bit voltage-output alternate, check the DAC8560 series (same footprint, internal reference).
