Note: All voltages are referenced to GND.
These are stress ratings only and functional operation is not
implied. Exposure to absolute maximum ratings for prolonged
time periods may affect device reliability.
Unless otherwise noted, VCC = 15V, RT = 10kΩ and CT = 3.3nF. Specifications are over the – 40°C to +85°C ambient temperature range.
Bold/blue specifications indicate enhanced performance features.
