Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to each parameter
in isolation, all other parameters having values within the recommended operating conditions. It should not be assumed that
limiting values of more than one parameter can be applied to the product at the same time. Exposure to the absolute maximum
ratings for extended periods can adversely affect device reliability.

Eye Safety Design
The laser driver is designed to be

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to each parameter
in isolation, all other parameters having values within the recommended operating conditions. It should not be assumed that
limiting values of more than one parameter can be applied to the product at the same time. Exposure to the absolute maximum
ratings for extended periods can adversely affect device reliability.
