TL084 Linear Operational Amplifier SOP-14

TL084 Linear Operational Amplifier IC (SOP-14) delivers high-performance, low-noise signal amplification for precision analog circuits. Engineers and hobbyists use this JFET-input op-amp in audio equipment, active filters, and instrumentation systems for its wide bandwidth and stable operation.

Key Features:

• JFET-Input Technology: Ensures high input impedance and low bias current for sensitive signal processing.
• Wide Bandwidth: Supports up to 4 MHz gain bandwidth for high-frequency applications.
• Low Noise: Minimizes signal distortion in audio and measurement circuits.
• SOP-14 Package: Compact surface-mount design saves PCB space.
• Quad Op-Amp: Integrates four independent amplifiers in a single IC.

Technical Specifications:

• Operating Voltage: ±5V to ±18V (dual supply) or 10V to 36V (single supply)
• Input Bias Current: 30 pA (typical)
• Slew Rate: 13 V/µs (ensures fast signal response)
• Temperature Range: –40°C to +105°C (industrial-grade reliability)

Mechanical Specifications:

• Package Type: SOP-14 (Surface-Mount)
• Lead Material: Tin-plated for solderability
• Moisture Sensitivity: MSL 3 (standard handling precautions apply)

Dimensions:

• Package Size: 8.65 mm × 3.9 mm × 1.35 mm (L × W × H)
• Lead Pitch: 1.27 mm (standard SMD spacing)

Pinout and Wiring:

• Pins 1, 7, 8, 14: Outputs of the four op-amps (OUT1 to OUT4)
