EL5226, EL5326
The maximum power dissipation actually produced by the IC
is the total quiescent supply current times the total power
supply voltage and plus the power in the IC due to the loads.
P DMAX = V S × I S + Σ [ ( V S - V OUT i ) × I LOAD i ]
when sourcing, and:
P DMAX = V S × I S + Σ ( V OUT i × I LOAD i )
when sinking.
Where:
? i = 1 to total 12
? V S = Supply voltage
? I S = Quiescent current
? V OUT i = Output voltage of the i channel
? I LOAD i = Load current of the i channel
By setting the two P DMAX equations equal to each other, we
can solve for the R LOAD 's to avoid the device overheat. The
package power dissipation curves provide a convenient way
to see if the device will overheat.
POWER SUPPLY BYPASSING AND PRINTED CIRCUIT
BOARD LAYOUT
Good printed circuit board layout is necessary for optimum
performance. A low impedance and clean analog ground
plane should be used for the EL5226 and EL5326. The
traces from the two ground pins to the ground plane must be
very short. The thermal pad of the EL5226 and EL5326
should be connected to the analog ground plane. Lead
length should be as short as possible and all power supply
pins must be well bypassed. A 0.1μF ceramic capacitor must
be place very close to the V S , V REFH , V REFL , and CAP
pins. A 4.7μF local bypass tantalum capacitor should be
placed to the V S , V REFH , and V REFL pins.
APPLICATION USING THE EL5226 AND EL5326
In the first application drawing, the schematic shows the
interconnect of a pair of EL5226 and EL5326 chips
connected to give 8 gamma corrected voltages above the
V COM voltage, and 8 gamma corrected voltages below the
V COM voltage.
