APPLICATIONS INFORMATION Figure 1 shows the OPA452 connected as a basic noninverting amplifier. The OPA452 can be used in virtually any op amp configuration. The OPA453 is designed for use in configurations with gains of 5 or greater. Power-supply terminals should be bypassed with 0.1µF capacitors, or greater, near the power-supply pins. Be sure that the capacitors are appropriately rated for the power-supply voltage used.
POWER SUPPLIES Where, The OPA452 and OPA453 may be operated from power supplies of ±10V to ±40V, or a total of 80V with excellent performance. Most behavior remains unchanged throughout the full operating voltage range. Parameters that vary significantly with operating voltage are shown in the Typical Characteristics. VO = output voltage For applications that do not require symmetrical output voltage swing, power-supply voltages do not need to be equal.
typical output current of 125mA. With ±40V power supplies, this creates an internal dissipation of 10W. This far exceeds practical heat sinking and is not recommended. If operation in this region is unavoidable, use the part with a heat sink. HEAT SINKING Power dissipated in the OPA452 or OPA453 will cause the junction temperature to rise. For reliable operation, the junction temperature should be limited to +125°C.
INCREASING OUTPUT CURRENT INPUT PROTECTION In those applications where the 50mA of output current is not sufficient to drive the desired load, output current can be increased by connecting two or more OPA452s or OPA453s in parallel, as shown in Figure 7. Amplifier A1 is the master amplifier and may be configured in virtually any op amp circuit. Amplifier A2, the slave, is configured as a unity gain buffer. Alternatively, external output transistors can be used to boost output current.
