3 Description

The OPA596 and OPA2596 (OPAx596) are highvoltage

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

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

The OPAx596 enable the next generation of highvoltage

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.
