TL082CP Dual JFET Op-Amp IC DIP-8 – Low-Noise, Wide-Bandwidth

TL082CP Dual JFET Op-Amp IC – DIP-8

The TL082CP is a dual JFET-input operational amplifier in a DIP-8 package – the lower-cost, slightly higher-noise sibling of the popular TL072. Both share the same JFET input architecture with very low input bias current (200pA typical), 3MHz gain-bandwidth product, and 13V/μs slew rate. The TL082 is an excellent general-purpose dual op-amp for audio circuits, active filters, and signal processing where two op-amp channels are needed and the tighter specifications of the TL072 are not required.

Electrical Specifications

• Part Number: TL082CP / TL082 / TL082ACP
• Package: DIP-8 (through-hole, 2.54mm pitch)
• Number of Op-Amps: 2 (dual)
• Input Type: JFET (low input bias current: ~200pA typical)
• Supply Voltage: ±2.25V to ±18V (dual supply)
• GBW: 3 MHz (typical)
• Slew Rate: 13 V/μs (typical)
• Input Offset Voltage: 3mV (typical), 15mV (max) – higher than TL072
• Input Noise Voltage: 18nV/√Hz (vs 18nV/√Hz for TL072 – similar)

TL082 vs TL072 – Which to Choose?

• TL072: Tighter offset spec (3mV typical, 6mV max), lower noise – preferred for precision audio
• TL082: Higher offset spec (3mV typical, 15mV max) – lower cost, suitable for general-purpose use
• Both have identical GBW (3MHz) and slew rate (13V/μs) – same speed
• Use TL072 for audio preamplifiers and precision circuits; TL082 for general signal processing

Typical Applications

• Audio circuits: Preamplifiers, tone controls, and signal conditioning
• Active filters: Low-pass, high-pass, and bandpass filter stages
• Synthesizers: VCO, VCF, and envelope generator circuits
• Instrumentation: Dual-channel signal amplification and conditioning
• Guitar effects: Overdrive, distortion, and modulation circuits
