ELECTRICAL SPECIFICATION
Recommend Operation Conditions
Operating ranges define the limits for functional
operation and parametric characteristics of the development
board. Note that the functionality of the development board
outside these operating ranges is not guaranteed. Operating
outside the recommended operating ranges for extended
periods of time may affect device reliability.

1. Voltage indicates DC value. With equalization pulse bus voltage must be between 11 V and 45 V
2. Higher voltages are possible. See Adjustable DC
