Product details

16-bit voltage-output DAC with SPI — what it is and where it fits

The AD7849CRZ-REEL is a 16-bit, single-channel, voltage-buffered DAC from Analog Devices built on a String DAC architecture. It settles to 16-bit accuracy in 10 µs typical, driven by an SPI data interface. The analog supply rails are ±14.25 V to ±15.75 V, and the digital supply is 5 V. An external voltage reference sets the output span. This part is rated for the industrial temperature range of -40°C to 85°C, making it suitable for precision analog output modules in factory automation, process control, and ATE instrumentation where a bipolar output swing and monotonic 16-bit performance are required.

Settling time and linearity — what the numbers mean for your BOM

The 10 µs typical settling time determines the maximum update rate for a full-scale step to ±0.5 LSB.

Lifecycle and sourcing

The AD7849CRZ-REEL is listed as Active with ROHS3 compliance. No last-time-buy or obsolescence notice is on record.

Frequently asked questions

Is AD7849CRZ-REEL obsolete?

No, the AD7849CRZ-REEL is listed as Active in production. No end-of-life or last-time-buy notice has been issued.

What is the settling time of AD7849CRZ-REEL?

The settling time is 10 µs typical for a full-scale step to 16-bit accuracy.

Does AD7849CRZ-REEL support SPI?

Yes, the data interface is SPI.

What package is AD7849CRZ-REEL available in?

It is supplied in Tape & Reel (TR) or Cut Tape (CT) in a 20-SOIC wide-body package (0.295", 7.50 mm width).

Does AD7849CRZ-REEL require an external reference?

Yes, the reference type is external.

What are the alternatives to AD7849CRZ-REEL?

The AD7849BRZ is a functionally identical 16-bit String DAC in the same package, but with looser INL (±16 LSB max) and DNL (±0.9 LSB max) specs. The AD5662 series offers a 16-bit String DAC in a smaller package (SOT-23) with a 2.7 V supply and extended temperature range to 125°C, but with ±1 LSB max DNL.
