Data Sheet AD5672R/AD5676R Octal, 12-/16-Bit nano DAC+ 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 m V 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 patibility - 50 MHz SPI with readback or daisy chain - 20-lead, Ro HS pliant TSSOP and LFCSP - 16-ball, Ro HS pliant 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. The AD5672R/AD5676R contain a power-down mode, reducing the current consumption to 1 µA typical while in power-down mode. The AD5676R is also available in a 16-ball WLCSP. Table 1.
