Description
The WM5615 is a 10-bit voltage output digital-toanalogue converter (DAC) with a buffered reference input (high impedance). The DAC produces a maximum output voltage that is twice the reference voltage and the DAC is monotonic. The device is simple to use, running from a single supply of 5V. A power-on reset function is incorporated to ensure repeatable start-up conditions.
