Feature Description (continued)

7.3.5 Rail-to-Rail Output

The OPA207 uses a rail-to-rail output stage capable of swinging within a few millivolts from either power supply

rail while maintaining high open-loop gain. Figure 40 shows a simplified drawing of the output stage circuit.

Resistors connected in series with each output transistor ensure a consistent output current limit. Limiting the

output current in this way ensures reliable operation of the OPA207 under short circuited conditions and protects

sensitive loads from being damaged by excessive current. Figure 41 and Figure 42 illustrate the maximum output

current available from the OPA207 at various temperatures.
