OPA2604_06 BURR-BROWN [Burr-Brown Corporation], OPA2604_06 Datasheet - Page 10

• Manufacturer Part Number: OPA2604_06
• Description: Dual FET-Input, Low Distortion OPERATIONAL AMPLIFIER
• Manufacturer: BURR-BROWN [Burr-Brown Corporation]

POWER DISSIPATION
The OPA2604 is capable of driving 600 loads with power
supply voltages up to 24V. Internal power dissipation is
increased when operating at high power supply voltage. The
typical performance curve, Power Dissipation vs Power Sup-
ply Voltage, shows quiescent dissipation (no signal or no
load) as well as dissipation with a worst case continuous sine
wave. Continuous high-level music signals typically produce
dissipation significantly less than worst case sine waves.

Copper leadframe construction used in the OPA2604 im-
proves heat dissipation compared to conventional plastic
packages. To achieve best heat dissipation, solder the device
directly to the circuit board and use wide circuit board traces.
OUTPUT CURRENT LIMIT
Output current is limited by internal circuitry to approxi-
mately 40mA at 25 C. The limit current decreases with
increasing temperature as shown in the typical curves.
