3 Description

The OPA596 and OPA2596 (OPAx596) are high-voltage (85V), high slew rate (100V/μs), micro-power (420μA), unity-gain stable operational amplifiers (op amps).

The OPAx596 enable the next generation of high-voltage systems, such as output load drivers in semiconductor test and digital power supplies by increasing the output voltage of the system though high-gain configurations. Low power consumption and industry-standard small packages allow the device to be used in high-density systems that are size constrained, while reducing the thermal management requirements for the system.

Through proprietary design techniques, the OPAx596 are capable of a very high slew rate with minimal power consumption to improve large-signal settling time and maximize the effective large-signal bandwidth. These devices also offers mux-friendly inputs that enable large differential voltage (up to 85V) and help improve settling behavior when compared to traditional inputs in multiplexed applications.

The OPAx596 are available in industry-standard packages and operates across the temperature range of –40°C to +125°C.
