PART MARKING*

Consult LTC Marketing for parts specified with wider operating temperature ranges. *Temperature grades are identified by a label on the shipping container.

The

● denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. V+ = 5V, V– = GND = 0V, TA = 25°C unless otherwise noted.
