PACKAGE/ORDER INFORMATION

The

● indicates specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. VCC = 12V, BAT = 4.8V, GND = PGND = 0V, unless otherwise noted.

Consult LTC Marketing for parts specified with wider operating temperature ranges.
