CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD1981BL features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
ST = Low Profile Quad Flatpack.
The AD1981BLJSTZ is a lead-free environmentally friendly product. It is manufactured using the most up-to-date materials and processes. The coating on the leads
of each device is 100% pure tin electroplate. The device is suitable for lead-free applications and is able to withstand surface-mount soldering at up to 255 °C (± 5°C).
In addition, it is backward compatible with conventional tin-lead soldering processes. This means that the electroplated tin coating can be soldered with tin-lead
solder pastes at reflow temperatures of 220°C to 235°C.
permanent damage to the device. This is a stress rating only; functional operation
of the device at these or any other conditions above those indicated in the
operational section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
