TL082CN

TL082CN is a dual low-noise JFET-input operational amplifier from Texas Instruments. It contains two independent op-amps in a single DIP-8 package (CN suffix) and is well-suited for high input impedance and low bias current applications such as sensor front-ends, audio, and precision instrumentation.
Key traits (typical): gain-bandwidth about 3 MHz; slew rate around 13 V/µs; input bias current in the tens of picoamps; input offset voltage a few millivolts. Power supply: typically ±5 V to ±15 V (10–30 V total), usable with dual supplies or single supply with proper bias. The input common-mode range does not reach the positive rail, and the output is not rail-to-rail, so headroom must be considered.
Common uses: preamplifiers, active filters, integrators, and buffer stages. Note: check the datasheet for exact pinout and operating conditions for your configuration.

TL082CN is a dual JFET-input op-amp. Common equivalents:
- TL072CN/TL072 (dual JFET, pin-compatible)
- LF353/LF353N (dual JFET, similar specs)
- OPA2132/OPA2134 (Analog Devices, similar performance)
Note: always check pinout, supply range, gain-bandwidth (GBW), and input bias current before substituting.

Here are the main features of TL082CN (dual JFET-input op-amps):
- Dual op-amps with JFET inputs for very high input impedance
- Very low input bias current (tens of picoamperes typical)
- Wide supply voltage range: roughly ±3 V to ±18 V (6–36 V total)
- Unity-gain stability (suitable for voltage followers and feedback configs)
- Gain-bandwidth product about 3 MHz; slew rate ~13 V/µs
- Low noise and low offset/offset current suitable for precision tasks
- Input common-mode range extends to the negative supply; output can swing close to rails under load
- Pin-compatible 8-pin DIP package (TL082CN)
Note: exact numbers (noise, offsets, rails, temp range) vary by part lot and operating conditions; commercial-grade TL082CN commonly specified for 0°C to +70°C.

- Pin count: 8 pins (DIP-8, TL082CN)

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is a U.S.-based multinational semiconductor company that designs and manufactures analog and digital integrated circuits and other electronic components.

TL082CN is a dual JFET-input op-amp. Its high input impedance, low input bias current and low noise suit:
- Audio front-ends: preamps, mixers, active filters
- Sensor conditioning: buffers for high-impedance sources (thermocouples, photodiodes, strain gauges)
- Instrumentation/precision amplification: instrumentation amps, difference amps, active filters
- Analog signal processing: integrators, differentiators, servo/error amplifiers
- General-purpose front-ends in DAQ/automation and robotics (buffering and gain stages)
Note: operates on standard ± supplies; not rail-to-rail outputs.

TL082CN uses an 8‑pin DIP (dual‑in‑line) package — the “N” suffix denotes the DIP-8 through‑hole package.
