Data Sheet 16-Channel, 12-/16-Bit nano DAC+ with 2 ppm/°C Voltage Reference TC, I2C Interface AD5673R/AD5677R Features GENERAL DESCRIPTION High performance High relative accuracy (INL): ±4 LSB maximum at 16 bits (AD5677R only) TUE: ±0.14% of FSR maximum Offset error: ±1.5 m V maximum Gain error: ±0.06% of FSR maximum Low drift, 2.5 V voltage reference TC: 2 ppm/°C typical 40 m A short-circuit current 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) 1.8 V logic patibility 400 k Hz I2C-patible serial interface 28-lead, 4 mm × 4 mm, Ro HS pliant LFCSP APPLICATIONS Optical transceivers Base station power amplifiers Process control (programmable logic controller (PLC) input/output cards) Industrial automation Data acquisition systems The AD5673R/AD5677R are low power, 16-channel, 12-/16-bit, buffered voltage output, digital-to-analog converters (DACs) that include a 2.5 V, 2 ppm/°C internal reference (enabled by default), and a gain select pin, resulting in 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 range and are guaranteed monotonic by design. The AD5673R/AD5677R are available in a 28-lead lead frame chip scale package (LFCSP) and incorporate a power-on reset (POR) circuit that ensures that the DAC outputs power up to and remain at zero scale or midscale until a valid write. The AD5673R/AD5677R contain a power-down mode that reduces the current consumption to 2 µA typical. Table 1.
