TL082ACP – TEXAS INSTRUMENTS

The Texas Instruments TL082ACP is a dual low-power, JFET-input operational amplifier (op-amp) packaged in an 8-pin PDIP. Operating from a ±3V to ±18V supply voltage range, it boasts a typical input bias current of 20nA and a maximum input offset voltage of 6mV, significantly lower than many comparable bipolar op-amps. This low bias current contributes to its suitability for high-impedance applications where input current leakage is a critical concern. The JFET input stage provides high input impedance (typically 10¹² Ω), further enhancing its performance in such applications._x000D_

The TL082ACP exhibits a unity-gain bandwidth of typically 3MHz and a slew rate of 15V/µs, making it suitable for audio and moderate-speed signal processing. Its low noise characteristics are advantageous in applications requiring high signal fidelity. Common use cases include instrumentation amplifiers, active filters (particularly those needing high input impedance), and precision analog signal conditioning circuits where low input bias current and drift are paramount. The device’s dual nature allows for compact designs requiring two independent op-amps, reducing board space and component count compared to using two separate single op-amps. However, its relatively low slew rate limits its applicability in high-speed applications.
