increases. For a single package, the sum of the RMS
output currents and voltages should be used to choose the
proper package.
THERMAL ANALYSIS
The THS4211 device does not incorporate automatic
thermal shutoff protection, so the designer must take care
to ensure that the design does not violate the absolute
maximum junction temperature of the device. Failure may
result if the absolute maximum junction temperature of
150
_ C is exceeded.
The thermal characteristics of the device are dictated by
the package and the PC board. Maximum power
dissipation for a given package can be calculated using the
following formula:
P
Dmax +
Tmax–TA
q
JA
where
PDmax is the maximum power dissipation in the amplifier (W).
Tmax is the absolute maximum junction temperature (°C).
TA is the ambient temperature (°C).
θJA = θJC + θCA
θJC is the thermal coefficient from the silicon junctions to the
case (
°C/W).
θCA is the thermal coefficient from the case to ambient air
(
°C/W).
For systems where heat dissipation is more critical, the
THS4211 is offered in an 8-pin MSOP with PowerPAD.
The thermal coefficient for the MSOP PowerPAD package
is substantially improved over the traditional SOIC.
Maximum power dissipation levels are depicted in the
graph for the two packages.
The data for the DGN
package assumes a board layout that follows the
PowerPAD layout guidelines referenced above and
detailed in the PowerPAD application notes in the
Additional Reference Material section at the end of the
data sheet.
