OPA549T

The OPA549T is a high-voltage/high-current Operational Amplifier, ideal for driving a wide variety of loads. This laser-trimmed monolithic integrated circuit provides excellent low-level signal accuracy and high output voltage and current. The OPA549T operates from either single or dual supplies for design flexibility. The input common-mode range extends below the negative supply. The OPA549 is internally protected against over-temperature conditions and current overloads. In addition, the OPA549 provides an accurate, user-selected current limit. Unlike other designs which use a power resistor in series with the output current path, the OPA549T senses the load indirectly. This allows the current limit to be adjusted from 0 to 10A with a resistor/potentiometer or controlled digitally with a voltage-out or current-out digital-to-analogue Converter (DAC). The enable/status (E/S) pin provides two functions.

• 8A Continuous and 10A peak high output current
• Wide output voltage swing
• Thermal shutdown and adjustable current limit protection
• Output disable control
• Thermal shutdown indicator
• 9V/µs High slew rate
• Control reference pin
• Green product and no Sb/Br

Avvertenze

Il CI può essere danneggiato dalle ESD. Si raccomanda di maneggiare tutti i CI con le precauzioni adeguate. L'inosservanza delle procedure di manipolazione e installazione appropriate può causare danni.
