TI OPA567AIRHGT

Общее назначениеRail-to-Rail1,2 МГц

Overview

The OPA567AIRHGT is a low-cost, high-current, operational amplifier designed for driving a wide variety of loads while operating on low-voltage supplies. It operates from either single or dual supplies for design flexibility and has rail-to-rail swing on the input and output. Output swing is within 300mV of the supply rails, with output current of 2A. Smaller loads allow an output swing closer to the rails. The OPA567AIRHGT is unity gain stable, easy to use, and free from the phase inversion problems found in some power amplifiers. High performance is maintained at voltage swings near the output rails. The OPA567AIRHGT provides an accurate user-selected current limit set with an external resistor, or digitally adjusted via a Digital-to-Analog Converter (DAC). The output of the OPA567AIRHGT can be independently disabled using the Enable pin. This feature saves power and protects the load. Two flags are provided. The current limit flag, IFLAG, warns of current limit conditions. TFLAG is a thermal flag that warns of thermal overstress. The TFLAG pin can be connected to the Enable pin to provide a thermal shutdown solution. The OPA567AIRHGT is available in a tiny 5mm x 5mm Quad Flatpack No-lead (QFN) package and features an exposed thermal pad that enhances thermal and electrical  characteristics. It is small and easy to heat sink. The OPA567AIRHGT is specified for operation over the industrial temperature range, –40°C to +85°C.
