Key Features
- Ultra-low input bias current of 200pA at 25°C (max 7nA) with JFET input architecture for minimal loading on high-impedance signal sources
- 86dB nominal common-mode rejection ratio (CMRR) with 75dB minimum for superior noise rejection in single-ended and differential signal chains
- 3MHz gain-bandwidth product with internal frequency compensation simplifying circuit design without external compensation components
- Low input offset voltage of 3mV maximum enabling precision DC amplification with minimal output error in instrumentation applications
Applications
The TL082BCPE4 is widely used in precision analog signal conditioning circuits including active filters, sample-and-hold amplifiers, and instrumentation front-ends where high input impedance and low bias current are critical. Its JFET inputs and 3MHz bandwidth make it excellent for audio preamplifiers, integrator circuits, and transimpedance amplifiers for photodetectors and other high-impedance sensors. The dual op-amp configuration in a single 8-pin DIP package simplifies PCB layout for stereo audio processing and differential signal amplification applications.

Frequently Asked Questions
What is the input bias current of the TL082BCPE4?
The TL082BCPE4 has a typical input bias current of 200pA (0.0002µA) at 25°C, with a maximum of 7nA (0.007µA). This extremely low bias current results from the JFET input architecture, making the device ideal for amplifying signals from high-impedance sources such as piezoelectric sensors, pH electrodes, and photodiode transimpedance circuits.
What is the bandwidth and slew rate of the TL082BCPE4?
The TL082BCPE4 has a gain-bandwidth product of 3MHz, providing adequate bandwidth for audio and general-purpose analog signal processing applications. The JFET input architecture also contributes to a relatively high slew rate compared to bipolar-input op amps, enabling faster large-signal response in active filter and waveform generation circuits.
What is the CMRR specification of the TL082BCPE4?
The TL082BCPE4 provides a common-mode rejection ratio (CMRR) of 86dB nominal and 75dB minimum. This high CMRR ensures effective rejection of common-mode noise and interference, making the device suitable for differential amplifier configurations in industrial sensor interfaces, audio equipment, and instrumentation systems where noise immunity is important.
What package does the TL082BCPE4 come in?
The TL082BCPE4 is packaged in an 8-pin PDIP (plastic dual in-line package), suitable for through-hole PCB mounting and breadboard prototyping. The 'E4' suffix indicates RoHS-compliant lead-free construction. The DIP package allows easy socket mounting for development and testing, and is widely available for prototyping and production in educational and industrial settings.
What applications is the TL082BCPE4 best suited for?
The TL082BCPE4 excels in applications requiring high input impedance and low bias current, including active filters (Butterworth, Chebyshev, Sallen-Key), audio preamplifiers, integrators, sample-and-hold circuits, and transimpedance amplifiers for optical sensing. Its dual op-amp configuration is convenient for stereo audio stages, instrumentation amplifiers, and differential signal processing in a single compact package.
