3 Description

The OPA596 and OPA2596 (OPAx596) are high-

voltage (85V), high slew rate (100V/μs), micro-power

(420μA), unity-gain stable operational amplifiers.

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.
