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