Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in
excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect device reliability.

Handling Precautions
Although protection circuitry has been designed into this device, proper precautions should be taken to avoid
exposure to electrostatic discharge (ESD) during handling and mounting. Agere Systems employs a human-body
model (HBM) and charged-device model (CDM) for ESD-susceptibility testing and protection design evaluation.
ESD voltage thresholds are dependent on the circuit parameters used in the defined model. No industrywide
standard has been adopted for the CDM. However, a standard HBM (resistance = 1500 Ω, capacitance = 100 pF)
is widely used and, therefore, can be used for comparison purposes. The HBM ESD threshold (>1500 V)
presented here was obtained by using these circuit parameters.
Application Considerations
A typical application is shown in Figure 2 for optical light intensity detection with temperature compensation by
using a thermistor with positive temperature coefficient of 0.42%.
