3581J

Overview

The Burr-Brown 3581J is a high-voltage single operational amplifier featuring an FET input stage. It supports supply voltages from ±32VDC to ±75VDC with a maximum output swing of ±70VDC. The device delivers up to ±60mA load current and includes automatic thermal shutoff protection. Key electrical parameters include a unity gain bandwidth of 100kHz, a slew rate of 15V/μs, and an input bias current of 20pA.

Feature Summary

• Monolithic FET input stage providing low bias currents and high input impedance
• Integrated thermal sensing circuitry for automatic shutdown during over-temperature conditions
• Output stage protected against short circuits to ground
• Input stage protected against overvoltages

Applications

• High voltage signal amplification
• Industrial control systems
• Test and measurement equipment

Procurement Notes

Verify the component status as Not Recommended for New Designs (NRND). Confirm that the TO-3 package matches the required mechanical constraints. Ensure the design accounts for the specific thermal dissipation capabilities without external heat sinks.

Selection Notes

Select this model when high voltage operation up to ±75VDC is required. Consider the 15V/μs slew rate for frequency response needs. Evaluate the need for thermal management solutions based on the expected power dissipation in the application environment.
