TL072 Operational Amplifier DIP-8
The TL072 is a high‑speed, low‑noise JFET‑input dual operational amplifier designed for general-purpose analog signal processing. It features well-matched, high-voltage JFETs and bipolar transistors in a monolithic IC, offering high slew rates, low input bias/offset currents, and excellent noise performance.
Features
- Wide common-mode and differential input voltage range
- Very low input bias current (20–200 pA) and offset current
- Low input noise voltage, en = 15 nV/√Hz (typical)
- High slew rate: 16 V/µs (typical)
- Low total harmonic distortion: 0.01% (typical)
- Internal frequency compensation for stability
- Output short-circuit protection and latch-up free operation
- High input impedance due to JFET input stage
