DESCRIPTION

The OPA452 and OPA453 are low-cost operational amplifi-

ers with high-voltage (80V) and high-current capabilities

(50mA). The OPA452 is unity-gain stable and has a gain

bandwidth product of 1.8MHz, whereas the OPA453 is opti-

mized for gains greater than 5 and has a 7.5MHz bandwidth.

The OPA452 and OPA453 are internally protected against

over-temperature conditions and current overloads. Power

supplies in the range of ±10V to ±40V can be used. Unlike

most other power op amps, the OPA452 and OPA453 have

ensured specifications over the entire power-supply range.

These laser-trimmed, monolithic integrated circuits provide

excellent low-level accuracy along with wide output swing.

Special design considerations assure that the product is

easy to use and free from phase inversion problems often

found in other amplifiers.

The OPA452 and OPA453 are available in TO220-7 and

DDPAK-7 options. They are specified for a junction tempera-

ture range of –40°C to +125°C.

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.
PAGE 11
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.
PAGE 12
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.
