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.
The 10 µs typical settling time determines the maximum update rate for a full-scale step to ±0.5 LSB.
No, the AD7849CRZ-REEL is listed as Active in production. No end-of-life or last-time-buy notice has been issued.
The settling time is 10 µs typical for a full-scale step to 16-bit accuracy.
Yes, the data interface is SPI.
It is supplied in Tape & Reel (TR) or Cut Tape (CT) in a 20-SOIC wide-body package (0.295", 7.50 mm width).
Yes, the reference type is external.
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.
