Consult LTC Marketing for parts speciï¬ed with wider operating temperature ranges.
*The temperature grade is identiï¬ed by a label on the shipping container.
ELECTRICAL CHARACTERISTICS The â denotes the speciï¬cations which apply over the â40°C to 85°C
temperature range, otherwise speciï¬cations are at TA = 25°C, VIN = 12V. Per typical application (front page) conï¬guration.
