The 3581J from B&B Smartworx is an integrated circuit operational amplifier designed for high-voltage applications. It features output voltage swings of up to ±145V and can handle large load currents of up to ±60mA.
The device incorporates an FET input stage with low bias currents of 20pA, which helps minimize offset voltages in high-resistance circuits. For reliability and protection, the 3581J includes automatic thermal shutoff circuitry that deactivates the amplifier when internal temperatures reach approximately 150°C. It also has input protection against overvoltages and output protection against short-circuits to ground.
Packaged in a TO-3 case, the 3581J can dissipate over 3W without a heat sink and up to 4.5W with a suitable heat sink. This makes it suitable for applications requiring significant power handling capabilities. The amplifier's design reduces source loading with an input impedance of 1011 Ohms and preserves system accuracy with a common-mode rejection ratio of 110dB.
