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
