description: |
  The AD3530/AD3530R (8-channel) and AD3531/AD3531R (4-channel) are low-power,
  16-bit, buffered voltage output digital-to-analog converters (DACs) with
  software-programmable gain controls, providing full-scale output spans of 2.5V
  or 5V for reference voltages of 2.5V. These devices operate from a single 2.7V
  to 5.5V supply and are guaranteed monotonic by design. The "R" variants
  include a 2.5V, 5ppm/°C internal reference, which is disabled by default.
