PRODMIX
When the inputs to the OPA6x7 are overdriven, the output voltage of the OPA6x7 smoothly limits at approximately 2.5V from the positive and negative power supplies. If driven to the negative swing limit, recovery takes approximately 500ns. When the output is driven into the positive limit, recovery takes approximately 6µs. Output recovery of the OPA627 can be improved using the output clamp circuit shown in Figure 6-5. Placing diodes at the inverting input prevent degradation of input bias current.
