LTC4012/ LTC4012-1/LTC4012-2 electrical characteristics Note 1: Stresses beyond those listed under Absolute Maximum Ratings Note 3: Operating junction temperature TJ (in °C) is calculated from may cause permanent damage to the device. Exposure to any Absolute the ambient temperature TA and the total continuous package power Maximum Rating condition for extended periods may affect device dissipation PD (in watts) by the formula TJ = TA + (θJA • PD). Refer to the reliability and lifetime. Applications Information section for details. Note 2: The LTC4012C is guaranteed to meet performance specifications Note 4: All currents into device pins are positive; all currents out of device over the 0°C to 85°C operating temperature range. The LTC4012I is pins are negative. All voltages are referenced to GND, unless otherwise guaranteed to meet performance specifications over the –40°C to 125°C specified. operating temperature range. Note 5: Output current may be limited by internal power dissipation.
