Frequently Asked Questions
What is the supply voltage range of the TL082BCDG4?
The TL082BCDG4 operates over a wide supply range of ±2.25 V to ±18 V (single-supply 4.5 V to 36 V equivalent), making it suitable for both low-voltage portable equipment and high-voltage industrial analog signal processing systems.
What is the input bias current of the TL082BCDG4?
Thanks to its JFET input stage, the TL082BCDG4 achieves a typical input bias current of only 0.2 nA at 25°C (maximum 7 nA average), which dramatically reduces loading on high-impedance sources such as piezo sensors, photodiodes, and electrostatic transducers.
What package does the TL082BCDG4 use?
It is housed in an 8-pin SOIC (Small Outline IC) package suitable for surface-mount assembly, with the 'G4' suffix indicating Green packaging and compliance with RoHS and JESD-609 lead-free solder standards for environmentally responsible manufacturing.
What is the common-mode rejection ratio of the TL082BCDG4?
The TL082BCDG4 provides a minimum CMRR of 75 dB and a typical CMRR of 86 dB, ensuring effective rejection of common-mode interference signals in differential measurement, audio, and instrumentation amplifier applications.
How does the TL082BCDG4 differ from the standard TL082?
The 'B' grade designation indicates a tighter input offset voltage specification of 5 mV maximum (versus 15 mV for the standard grade), making the TL082BCDG4 better suited for precision signal conditioning designs where DC accuracy is critical.
