TL082

Texas Instruments · Operational Amplifier · SOIC-8

The TL082 packs two JFET-input operational amplifiers into a single 8-pin body. The JFET inputs give high input impedance and low bias current, while the 13 V/us slew rate and 3 MHz bandwidth suit active filters, integrators, and audio signal conditioning.

Pinout

Pin Name Type Function
1 1OUT output Output of amplifier 1. Class-AB output stage with continuous short-circuit protection; drives loads referenced between VCC- and VCC+.
2 1IN- input Inverting input of amplifier 1. High-impedance JFET gate input. Input pins are diode-clamped to the power-supply rails; overdrive current must be limited to <=10 mA.
3 1IN+ input Non-inverting input of amplifier 1. High-impedance JFET gate input. Common-mode input range extends to VCC+ (see Recommended Operating Conditions).
4 VCC- power_in Negative supply rail (or ground for single-supply operation). Total supply span (VCC+) - (VCC-) must be between 10 V and 30 V for NS/PS/TL08xM packages, or 4.5 V to 40 V for other devices. Absolute-max supply voltage is 36 V (NS/PS/TL08xM) or 42 V.
5 2IN+ input Non-inverting input of amplifier 2. High-impedance JFET gate input. Common-mode input range extends to VCC+.
6 2IN- input Inverting input of amplifier 2. High-impedance JFET gate input. Input pins are diode-clamped to the power-supply rails; overdrive current must be limited to <=10 mA.
7 2OUT output Output of amplifier 2. Class-AB output stage with continuous short-circuit protection; drives loads referenced between VCC- and VCC+.
8 VCC+ power_in Positive supply rail. Total supply span (VCC+) - (VCC-) must be between 10 V and 30 V (NS/PS/TL08xM) or 4.5 V to 40 V (other devices). Bypass to VCC- with a local decoupling capacitor.
