Characteristics subject to change without notice
Absolute Maximum Ratings
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Recommended operating conditions
indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specific -
ations and test conditions, see Electrical Characteristics.
Note 2: This device is a highly sensitive CMOS ac current amplifier with an ESD rating of JEDEC HBM class 0 (<250V). Handling and
assembly of this device should only be done at ESD protected workstations.
