Power Dissipation
The EL9111 and EL9112 are designed to operate with ±5V
supply voltages. The supply currents are tested in
production and guaranteed to be less than 39mA per
channel. Operating at ±5V power supply, the total power
dissipation in Equation 1 is:

For a QFN 20 Ld package in a properly layout PCB
heatsinking copper area, +37°C/W θ
can be achieved. To disperse the heat, the bottom
heatspreader must be soldered to the PCB. Heat flows
through the heatspreader to the circuit board copper then
spreads and converts to air. Thus the PCB copper plane
becomes the heatsink. This has proven to be a very effective
technique. "See Technical Bulletin 389
(http://www.intersil.com/data/tb/TB389.pdf) for additional
QFN PCB layout information."
