3583AM

The 3583AM is a high voltage, high speed hybrid operational amplifier designed for a wide variety of programmable power supply and transducer driver applications.

The 3583AM operates over a wide power supply range (±50V to ±150V) and provides outputs up to 75mA.Laser-trimmed FET input circuitry provides low offset voltage (3mV max) and low input bias current (20pA max). Thermal shut-down circuitry protects internal circuitry from excessive power dissipation.Commercial and industrial temperature range models are available. The 3583AM's hermetic 8-pin TO-3 package is electrically isolated from all internal circuitry.

The 3583AM has internal thermal shut-down circuitry that activates at a case temperature of approximately 150 or higher. As this circuitry is activated, the output current drive is reduced. As the case temperature returns to less than the activation temperature, operation will return to normal. A heat sink may be required depending on load and signal conditions.Note that a 75mA output may not be safe for all output voltages-see typical performance curve "Safe Operating Area". Applications such as current sources where output voltage may be low (or the opposite polarity of the output current) can overstress the output stage.The thermal shut-down circuit will normally protect the amplifier during a short-circuit to ground. It will not protect against short-circuit to one of the power supplies. The typical performance curve "Safe Operating Area" shows that the large stress occurring during this high voltage condition may cause damage if it exceeds 5ms duration. The thermal protection circuitry will not activate fast enough to protect the device from short-circuits to one of the power supplies.The package case of the 3583AM is electrically isolated from all circuitry. No special insulating hardware is required.Although not absolutely required, it is recommended that the case be connected to ground.
