TL072CP 30V Dual Low-Noise JFET Operational Amplifier IC (8-Pin DIP)
📋 Overview The TL072 is a dual-channel, JFET-input operational amplifier from Texas Instruments — the two-amp sibling of the industry-standard TL071. It packs two independent, low-noise op amps into a single 8-pin DIP, so you get two amplifier stages while using half the board space and half the parts count of two single op amps. Rated for a 30V maximum supply with a 13V/µs slew rate, low input offset voltage, and low noise, it's a dependable choice for audio circuits, sensor signal conditioning, and general-purpose analog designs where you need more than one amplifier stage. New to op amps? Think of the TL072 as two TL071-style signal "helpers" built into one chip — handy for stereo audio (left/right channels), a two-stage filter, or any circuit that needs a matched pair of amplifiers sharing the same power supply. ⭐ Key Features Dual channel — two independent op amps in one 8-pin package 30V maximum supply voltage — higher headroom than many general-purpose op amps 13V/µs typical slew rate for fast-changing signals 3MHz gain-bandwidth product Low input offset voltage for accurate, stable readings Low input noise — ideal for audio and precision signal work Output short-circuit protection built in Industry-standard, second-source-friendly pinout — easy to substitute in existing designs Common, easy-to-solder 8-pin DIP package for through-hole prototyping 🎯 Applications Stereo audio circuits: preamps, mixers, and tone controls where matched left/right channels benefit from sharing one chip Multi-stage filters: build a two-pole active filter (e.g., a buffer stage plus a filter stage) using both amplifiers on one IC Sensor signal conditioning: amplify and buffer two separate sensor signals, or use one channel for gain and the other for buffering Instrumentation and test equipment: dual buffer or comparator stages in measurement gear Higher-voltage analog stages: the 30V supply rating gives extra headroom for designs running on ±12V to ±15V rails General-purpose amplification: inverting/non-inverting amplifier stages, voltage followers, and dual comparators in hobbyist and educational projects 📌 Pin Diagram (8-Pin DIP) Pins 2 & 3 (1IN-, 1IN+): Inverting and non-inverting inputs, amplifier 1 Pin 1 (1OUT): Output, amplifier 1 Pins 5 & 6 (2IN+, 2IN-): Non-inverting and inverting inputs, amplifier 2 Pin 7 (2OUT): Output, amplifier 2 Pins 4 & 8 (V-, V+): Power supply connections (shared by both amplifiers) 📊 Specifications Device TL072CP (dual channel) Package 8-Pin PDIP Maximum supply voltage 30V Input type JFET (low bias current) Slew rate 13V/µs (typical) Gain-bandwidth product 3MHz Input offset voltage Low, typical single-digit mV or better Operating temperature 0°C to 70°C (C-grade) Short-circuit protection Yes, continuous, per amplifier Both amplifiers on the TL072CP share the same power supply pins and specifications.
