Calculating Power Consumption
The total power available for the power supplies, analog outputs, and digital outputs is limited to 500 mW (typical)/100 mW (minimum). To calculate the total power consumption of the power supplies, multiply the output voltage by the load current for each voltage rail and sum them together. For digital output power consumption, multiply 3.3 V by the load current. For analog output power consumption, multiply 15 V by the load current. Using audio output subtracts 100 mW from the total power budget.
If you use 50 mA on +5 V, 2 mA on +15 V, 1 mA on -15 V, use four DIO lines to drive LEDs at 3 mA each, and have a 1 mA load on each AO channel, the total output power consumption is 364.6 mW
- 5 V × 50 mA = 250 mW
- |+15 V| × 2 mA = 30 mW
- |-15 V| × 1 mA = 15 mW
- 3.3 V × 3 mA x 4 = 39.6 mW
- 15 V × 1 mA x 2 = 30 mW
- Total output power consumption = 250 mW + 30 mW + 15 mW + 39.6 mW + 30 mW = 364.6 mW
