Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Recommended operating conditions indic-

ate conditions for which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifica -

tions 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 as-

sembly of this device should only be done at ESD protected workstations.
