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.

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 AD1981B 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.
