1 Junction-to-ambient thermal resistance (θJA) of the package was calculated

or simulated on a multilayer PCB.

2 The ADP1828 can be damaged when the junction temperature limits are

exceeded. Monitoring ambient temperature does not guarantee that TJ

is within the specified temperature limits. In applications with moderate

power dissipation and low PCB thermal resistance, the maximum ambient

temperature can exceed the maximum limit as long as the junction tem-

perature is within specification limits. The junction temperature, TJ, of the

device is dependent on the ambient temperature, TA, the power dissipation

of the device, PD, and the junction to ambient thermal resistance of the

package, θJA. Maximum junction temperature is calculated from the ambient

temperature and power dissipation using the formula TJ = TA + PD × θJA.

Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.

Absolute maximum ratings apply individually only, not in

combination. Unless otherwise specified all other voltages

are referenced to GND.
