14-bit current-steering DAC with 11 µs settling
The MAX5884EGM+D is a 14-bit current-steering digital-to-analog converter from Analog Devices, delivering a typical settling time of 11 µs. That settling figure sets the maximum update rate for applications like arbitrary waveform generation or closed-loop control outputs — at 11 µs you can update the DAC output roughly every 90 kHz without waiting for the previous value to stabilize. It uses a current-steering architecture with differential output, which means the output is a current sink rather than a buffered voltage — the external load resistor sets the voltage swing. Differential output improves common-mode noise rejection, important in noisy industrial or communications environments. The data interface is parallel, so the DAC expects a full 14-bit word on its input pins every conversion cycle. This makes it a good fit for FPGA or high-speed microcontroller buses that can present a parallel word in one clock cycle.
Single 3.3 V supply, dual reference options
The reference can be either external or internal, giving the designer flexibility to use a precision external reference for tighter accuracy or the internal reference to save board space. INL and DNL are specified at ±0.8 LSB and ±0.5 LSB respectively. These numbers tell you the maximum deviation from an ideal transfer function — at 14 bits, ±0.8 LSB INL means the output stays within about 0.005% of full scale, which is typical for a current-steering DAC in this class.
Active lifecycle, ROHS3 compliant
It is ROHS3 compliant, so it meets the latest European hazardous-substance restrictions. The package is a tube (48-VFQFN exposed pad); the marking and date-code should be consistent with Analog Devices' factory laser-etch standards — any mismatch in font or alignment is a red flag for counterfeit detection.
