Descripción general

Description

TL082CN is a TI dual high-speed, low-noise JFET-input operational amplifier in an 8-pin DIP package (CN). It provides two identical op-amps with high input impedance and low input bias current, good for precision and audio/sensor circuits.
Key specs (per amplifier):
- Supply: ±3 to ±18 V (6–36 V total)
- Unity-gain bandwidth: ~3 MHz; Slew rate ≈ 13 V/µs
- Input common-mode: down to negative rail; not to the positive rail
- Output: swing within about 1–2 V of rails under light load
Pinout (DIP-8): V+ = pin 8, V− = pin 4; Op‑amp A: output 1, inverting input 2, noninverting input 3; Op‑amp B: output 7, inverting input 6, noninverting input 5.
Typical uses: audio preamps, active filters, instrumentation/sensor front-ends, general-purpose op-amp tasks needing low bias current.

Features

TL082CN features (concise):
- Dual JFET-input operational amplifiers with very high input impedance
- Low input bias current (pA range) and low input offset
- Low noise (≈15 nV/√Hz)
- Gain-bandwidth product ~3 MHz
- Slew rate ~13 V/µs
- Wide supply voltage: ±3 V to ±18 V (6–36 V total)
- Not rail-to-rail; input common-mode range includes negative supply
- Moderate output drive (typically tens of mA)
- DIP-8 package (CN variant) suitable for general-purpose analog applications
Used for audio, instrumentation, and sensor conditioning where low noise and high impedance are beneficial.

Package

TL082CN is an 8-pin DIP (dual inline) package (PDIP).

Pinout

- Pin count: 8 pins (8-pin package).
- Function: Dual JFET-input operational amplifier (two independent, high-gain, internally compensated op-amps in one package).
Typical DIP-8 pinout (TL082CN):
- 1: Output A
- 2: Inverting input A
- 3: Non-inverting input A
- 4: V−
- 5: Non-inverting input B
- 6: Inverting input B
- 7: Output B
- 8: V+

Manufacturer

- Manufacturer: Texas Instruments (TI)
- What kind of company: American multinational corporation that designs, manufactures, and sells semiconductors and integrated circuits (analog and digital ICs). It is one of the world’s largest semiconductor companies.

Application

TL082CN is a dual JFET-input op-amp with high input impedance and low bias current. Typical applications:
- Audio preamplifiers and active filters
- Buffering high-impedance sensors
- Instrumentation and signal-conditioning stages
- Analog signal processing (filters, integrators, differentiators, summing)
- ADC/DAC driver stages and general-purpose use in industrial control/servo applications
Note: not a comparator.

Equivalent

TL082CN is a dual JFET-input op-amp. Common equivalents (pin-compatible or drop-in substitutes) include:
- TL082 (same device in another package)
- TL072 (dual JFET-input op-amp)
- LF353 / LF353N (dual JFET-input op-amp)
Note: always verify pinout, supply rails, offset voltage, and bias currents, as substitutions may differ in performance.
