What are the key features of TL082ACPE4?
- JFET input stage provides 200 pA maximum input bias current at 25°C for high-impedance signal conditioning
- 86 dB typical common-mode rejection ratio (75 dB minimum) for accurate differential signal amplification
- 4 MHz gain-bandwidth product with internal frequency compensation for stable unity-gain operation
- Dual op-amp configuration in 8-pin DIP package enables two independent amplifier stages in a single device
- Wide supply voltage range of ±5 V to ±15 V compatible with standard bipolar power supplies
What is TL082ACPE4 used for?
The TL082ACPE4 is used in audio preamplifiers, active filter networks, and precision instrumentation amplifier stages where JFET inputs provide the very low bias current needed to avoid loading high-impedance sources like microphones and piezoelectric sensors. Its 86 dB CMRR and wide supply range make it a reliable choice for signal conditioning in industrial data acquisition systems and laboratory test equipment. The through-hole 8-pin DIP package simplifies prototype assembly and repair in benchtop and educational electronics applications.

Frequently Asked Questions
What makes the JFET input of the TL082ACPE4 preferable for high-impedance sensor amplification?
The TL082ACPE4 has a maximum input bias current of 200 pA at 25°C due to its JFET input stage, compared to several hundred nanoamps for bipolar op-amps. This 1000x lower bias current prevents voltage errors when the source impedance is in the megaohm range, as encountered with piezoelectric transducers, pH electrodes, and electret microphone capsules.
What gain-bandwidth product does the TL082ACPE4 achieve, and how does this limit closed-loop bandwidth?
The TL082ACPE4 offers a 4 MHz gain-bandwidth product. At a closed-loop gain of 10 V/V (20 dB), the usable bandwidth is approximately 400 kHz, suitable for audio and low-frequency instrumentation applications. At unity gain the full 4 MHz bandwidth is available with the internal frequency compensation ensuring stable operation.
How does the TL082ACPE4 compare to TL082BCP in CMRR specification?
The TL082ACPE4 (A-grade) guarantees a minimum CMRR of 75 dB and typical 86 dB, while the standard TL082CP specifies 70 dB minimum. The 5 dB improvement in minimum CMRR makes the A-grade variant preferable in precision differential amplifier stages where common-mode noise rejection must be guaranteed across the full operating temperature range of -55°C to +125°C.
Is the TL082ACPE4 suitable for audio mixing console preamplifier applications?
Yes, the TL082ACPE4 is widely used in audio mixing console input stages and EQ filter sections. Its JFET inputs keep bias current below 200 pA at 25°C, preventing hum or DC offset when coupled through high-value coupling capacitors, and its 4 MHz bandwidth covers the full 20 Hz to 20 kHz audio range with over 200x gain margin.
Which supply voltage configurations does the TL082ACPE4 support for laboratory bench designs?
The TL082ACPE4 operates from ±5 V to ±15 V split supplies, making it directly compatible with standard bipolar laboratory bench power supplies. The ±15 V maximum supply gives a ±12 V typical output swing, providing 24 V peak-to-peak headroom for large-signal audio and measurement applications without clipping at full-scale inputs.
