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 for this device, proper precautions should be taken to avoid
exposure to electrostatic discharge (ESD) during handling and mounting. Agere Systems Inc. employs a human-
body model (HMB) 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
industry-wide standard has been adopted for 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 (>500 V)
presented here was obtained by using these circuit parameters.
Application Considerations
Safe Handling of the High Voltage Device
LSP2908 is capable of operating with a negative power supply of up to –300 V or a positive power supply of up to
160 V. Due to the presence of high voltages, special care should be paid to safety issues.
Bypass Capacitors/Protection Series Resistor for the Power Supplies
To minimize noise coupling to the output, 0.1 µF bypass capacitors should be placed as close as possible to all
power supply pins.
