Provides an SPI based interface to the AD5724R, AD5734R, and the AD5754R Quad 12-/14-/16-Bit Unipolar/Bipolar Voltage Output DACs.
The outputs can be set two ways, either by setting the analog value or by setting the voltage directly. The analog values are integers with the range determined by the resolution and whether the output is set to unipolar or bipolar. This is similar to Arduino analogWrite and this method is provided as an alternative name for convenience. Alternatively, the output voltages can be set directly. Voltages are floats with the minimum and maximum values determinded by the output range. By default, the outputs are updated immediately after they are set, but the outputs can be updated synchronously by using the simultaneous update methods.
| PIN | CONNECTION |
