The OPA452 and OPA453 are low-cost operational amplifiers 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 optimized 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 temperature range of –40°C to +125°C.
