There are various reasons why you might need to split a voltage rail in your design. Perhaps the design contains a sensor or an IC that requires a bipolar supply, or you need to make the best use of ...

The ADHV4710 op amp operates on dual supplies from ±12 to ±55 V, delivering output current of ±100 mA at the higher voltages. A ±1,300-V/μs output slew rate into capacitive loads up to 1 nF (1000 pF).
