TL084CN OP-AMP
Share :
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.
