This library provides a clean, lightweight API to control AD569x DACs, including DAC output updates, voltage conversion helpers, power modes, reference control, and gain configuration.

• Supports AD569x I2C DAC devices (16-bit interface)
• Raw DAC control:
  • Write input register
  • Update output register
  • Write + update in a single command
• Control register support:
  • Software reset
  • Internal / external reference selection
  • 1× / 2× gain selection
  • Power-down modes
• Compatible with:
  • AVR (UNO, Mega, etc.)
  • ESP32
  • ESP8266
  • Any Arduino core supporting Wire

⚠️ Output range, gain behavior, and reference options depend on the specific AD569x variant. Always verify against the device datasheet.
