Product Details

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.

Product Highlights

  1. High Relative Accuracy (INL).
    AD5671R (12-bit): ±1 LSB maximum
    AD5675R (16-bit): ±3 LSB maximum
  2. Low Drift 2.5 V On-Chip Reference

Applications

  • Optical transceivers
  • Base-station power amplifiers
  • Process control (PLC input/output cards)
  • Industrial automation
  • Data acquisition systems

Precision DAC Error Budget Tool

The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
