AD5671R

Data Sheet Octal, 12-/16-Bit nanoDAC+ with 2 ppm/°C Reference, I2C Interface AD5671R/AD5675R 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 Easy implementation User selectable gain of 1 or 2 (GAIN pin/bit) 1.8 V logic compatibility 400 kHz I2C-compatible serial interface 20-lead, RoHS-compliant TSSOP and LFCSP APPLICATIONS Optical transceivers Base station power amplifiers Process control (PLC input/output cards) Industrial automation Data acquisition systems 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. Table...
