Product Details

The AD5679R is a low power, 16-channel, 16-bit, buffered voltage output, digital-to-analog converter (DAC) that includes 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 device operates from a single, 2.7 V to 5.5 V supply range and is guaranteed monotonic by design. The AD5679R is available in a 28-lead lead frame chip scale package (LFCSP) and incorporates a power-on reset (POR) circuit that ensures that the DAC outputs power up to and remains at zeros-cale until a valid write. The AD5679R contains a power-down mode that reduces the current consumption to 2 μA typical when in power-down mode.

Applications

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