AD5672R

Data Sheet AD5672R/AD5676R Octal, 12-/16-Bit nanoDAC+ with 2 ppm/°C Reference, SPI Interface FEATURES ► High performance ► High relative accuracy (INL): ±3 LSB maximum at 16 bits ► Total unadjusted error (TUE): ±0.14% of FSR maximum ► Offset error: ±1.5 mV maximum ► Gain error: ±0.06% of FSR maximum ► Low drift 2.5 V reference: 2 ppm/°C typical ► Wide operating ranges ► −40°C to +125°C temperature range ► 2.7 V to 5.5 V power supply range ► Simplified implementation ► User selectable gain of 1 or 2 (GAIN pin/gain bit) ► 1.8 V logic compatibility ► 50 MHz SPI with readback or daisy chain ► 20-lead, RoHS compliant TSSOP and LFCSP ► 16-ball, RoHS compliant WLCSP (AD5676R) APPLICATIONS ► Optical transceivers ► Base station power amplifiers ► Process control (PLC input/output cards) ► Industrial automation ► Data acquisition systems FUNCTIONAL BLOCK DIAGRAM GENERAL DESCRIPTION The AD5672R/AD5676R 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 AD5672R/AD5676R 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 that the DAC outputs power up to zero scale or midscale and remains there until a valid write.
