7 Detailed Description
7.1 Overview
The OPA541 uses a JFET input stage, followed by a main voltage gain stage, and a class A/B high current output stage.
7.2 Functional Block Diagram
7.3 Feature Description
The OPA541 JFET input stage reduces circuit loading and input bias currents. The class A/B high current output stage incorporates temperature compensated biasing to reduce crossover distortion. The output stage also includes a user settable current limit for amplifier and circuit protection.
7.4 Device Functional Modes
The OPA541 has a single functional mode. The OPA541 is operational when the power supply voltage exceeds 10 V (±5 V) and less than 80 V (±40 V).
