The PD due to the load drive depends on the application. The P
Parameter Rating
D due to load drive is calculated by multiplying the load current by the associated voltage drop across the device. RMS Supply Voltage1 voltages and currents must be used in these calculations. Transient 60 V Continuous 50 V Airflow increases heat dissipation, effectively reducing θJA. Power Dissipation (PDISS) See Figure 3 Additional metal that is directly in contact with the package Differential Input Voltage ±80 V leads from metal traces through vias, ground, and power planes ±IN Pin Voltage reduces θJA. Continuous −5 V to+ 80 V Figure 3 shows the maximum P Survival −10 V to +80 V D vs. TA for the single and dual 6-lead TSOT packages on a JEDEC standard, 4-layer board, with ±IN Pin Current 30 mA SHDN Pin Voltage −0.3 V to +60 V −VS connected to a pad that is thermally connected to a PCB Electrostatic Discharge (ESD) plane. θJA values are approximations.

THERMAL RESISTANCE
Junction temperatures (T Thermal performance is directly linked to printed circuit board J) exceeding 125°C promote accelerated aging. The ADA4099-1 demonstrates ±25 V supply (PCB) design and operating environment. Careful attention to operation beyond 1400 hours at T PCB thermal design is required. A = 140°C.
MAXIMUM POWER DISSIPATION
θJA is the junction to ambient thermal resistance. The maximum safe power dissipation (PDISS) on the device is

TJ on the die. At approximately TC = 150°C, which is the glass UJ-6 192 C/W transition temperature, the properties of the plastic changes. Exceeding this temperature limit, even temporarily, may change

the stresses that the package exerts on the die, which permanently shifts the parametric performance of the ADA4099-1. Exceeding TJ = 175°C for an extended period may result in changes in the silicon devices and may potentially cause failure of the device. The PDISS on the package is the sum of the quiescent power dissipation and the power dissipated in the package due to the output load drive. The quiescent power is expressed in the following equation: VSY × ISY where ISY is the quiescent current. Rev.
