TL062 Dual Low-Power JFET-Input Op Amp by TI 200µA Supply 3.5V/µs Slew

Description

Product Overview

The TL062 is a dual operational amplifier that combines the low power consumption of a JFET-input stage with the performance needed for modern portable and battery‑powered designs. Each amplifier draws only 200 µA from the supply, allowing designers to keep overall system current well below the milliamps range while still achieving a slew rate of 3.5 V/µs. This speed is sufficient for most audio, sensor, and instrumentation applications where rapid signal transitions are required. The device operates from a single supply voltage ranging from 3 V to 36 V, and its common‑mode input range includes the positive rail, giving designers flexibility in single‑supply configurations. Internally, the TL062 includes short‑circuit protection on the output stage, preventing damage in the event of a load fault. The DIP‑8 package is specifically chosen for breadboard‑friendly prototyping, making it easy to test and integrate into development boards without the need for specialized sockets.

Usage

Engineers and hobbyists alike find the TL062 ideal for a wide variety of signal‑conditioning tasks. In portable medical devices, the low quiescent current helps extend battery life while the high slew rate ensures accurate waveform reproduction for ECG or pulse‑oximetry front‑ends. In audio equipment, the JFET input stage provides low noise and low bias currents, making the TL062 suitable for pre‑amplifier stages in mixers, guitar pedals, and headphone amplifiers. The wide input voltage range also allows the amplifier to be used in single‑supply sensor interfaces, such as thermocouple amplifiers, strain‑gauge bridges, and photodiode transimpedance stages. Because the device tolerates short‑circuit conditions, it can be safely employed in environments where accidental overloads may occur, such as robotics or automotive sensor modules. The DIP‑8 footprint simplifies integration into both hand‑wired prototypes and printed‑circuit‑board designs, enabling rapid iteration from concept to production.
