TL084CN OP-AMP

The TL084CN is a classic general-purpose Quad JFET-Input Operational Amplifier (Op-Amp) IC. It is a control component, not a power component, and is key for implementing precise sensing and control required to meet the Canvas's compliance demands.

Here are its core specifications and relevance:

• Type: Operational Amplifier (Op-Amp), featuring JFET inputs.

• Function: Contains four independent Op-Amps in a single package. Used for amplification, buffering, filtering, and comparison.

• Family:BIFET technology (Bipolar and Field-Effect Transistors), offering high input impedance and low bias current, which is excellent for sensitive measurements.

• Supply Voltage (V_CC): Wide range, typically 5V to 18 V (or 10 V to 36V single supply).

• Package: Standard 14-pin Dual In-line Package (DIP) (the 'CN' suffix often denotes DIP).

• Relevance to Safety/Compliance: The TL084CN would be vital in the inverter's control loop for implementing the sensing logic required by the safety features:

  • Current Sensing: Amplifying the tiny voltage signal from a current shunt to accurately measure the current flow, essential for over-current Protection.

  • Voltage Feedback: Creating a stable, precise feedback signal to regulate the output AC voltage, helping the system adhere to Standards.

  • Thermal Monitoring: Conditioning the signal from the thermal sensor to trigger the recommended 120C shutdown Protection mechanism.
