TL072CP Dual JFET-Input Op-Amp IC — DIP-8, Low-Noise Audio (5-Pack)
The TL072CP is a dual JFET-input operational amplifier in a DIP-8 through-hole package, featuring a 13V/μs slew rate, 3MHz gain-bandwidth product, and ultra-low input bias current of just 65pA. It is the standard op-amp for audio preamplifiers, active filters, and signal processing circuits where low noise and high input impedance are required.

Why Choose TL072CP?
- JFET Inputs — 65pA bias current; ideal for high-impedance sources (guitar pickups, microphones, piezo sensors)
- 13V/μs Slew Rate — Handles audio frequencies up to ~100kHz without slew-rate distortion
- Low Noise — 18nV/√Hz suitable for audio preamp and signal conditioning
- ±18V Supply — Wide supply range for ±15V audio equipment and ±12V systems
- Dual Package — Two op-amps in DIP-8; stereo preamp in one IC
Typical Applications
- Guitar and instrument preamplifier (high-impedance input)
- Active low-pass, high-pass, and band-pass audio filters
- Stereo audio mixer summing amplifier
- Piezoelectric sensor signal conditioning
- Precision voltage follower (buffer) for high-impedance sources
- Waveform generator integrator and differentiator
FAQ
Q: Can TL072CP run on a single 9V supply?
A: Yes — use single supply (9V to V+ and GND to V−). Bias inputs at VCC/2 (4.5V) via voltage divider for AC-coupled audio signals.
Q: Is TL072CP suitable for phono (RIAA) preamp?
A: Yes — low bias current and adequate GBW make it suitable for RIAA equalization. NE5532 is preferred for lowest noise, but TL072 is widely used in budget phono stages.
