Octal, 12-/16-Bit nanoDAC+ with  
2 ppm/°C Reference, I2C Interface  
AD5671R/AD5675R  
Data Sheet  
FEATURES  
GENERAL DESCRIPTION  
The AD5671R/AD5675R are low power, octal, 12-/16-bit  
buffered voltage output digital-to-analog converters (DACs).  
They include a 2.5 V, 2 ppm/°C internal reference (enabled by  
default) and a gain select pin giving a full-scale output of 2.5 V  
(gain = 1) or 5 V (gain = 2). The devices operate from a single  
2.7 V to 5.5 V supply and are guaranteed monotonic by design.  
The AD5671R/AD5675R are available in a 20-lead TSSOP and in  
a 20-lead LFCSP and incorporate a power-on reset circuit and a  
RSTSEL pin that ensures the DAC outputs power up to zero scale  
or midscale and remain there until a valid write. The AD5671R/  
AD5675R contain a power-down mode, reducing the current  
consumption to 1 μA typical while in power-down mode.  
High performance  
High relative accuracy (INL): 3 LSB maximum at 16 bits  
Total unadjusted error (TUE): 0.14ꢀ of FSR maximum  
Offset error: 1.5 mꢁ maximum  
Gain error: 0.06ꢀ of FSR maximum  
Low drift 2.5 ꢁ reference: 2 ppm/°C typical  
Wide operating ranges  
−40°C to +125°C temperature range  
2.7 ꢁ to 5.5 ꢁ power supply  
Easy implementation  
User selectable gain of 1 or 2 (GAIN pin/bit)  
1.8 ꢁ logic compatibility  
400 kHz I2C-compatible serial interface  
Robust 2 kꢁ HBM and 1.5 kꢁ FICDM ESD rating  
20-lead, RoHS-compliant TSSOP and LFCSP
