Introduction

TL072IDRE4 is a low-power high-bandwidth dual-channel JFET input operational amplifier (op-amp) designed for use in professional and audio applications. It features very low offset voltage, low input bias currents, high gain bandwidth product (GBWP), low input capacitance, low distortion and very low supply current. This makes it ideal for audio and instrumentation applications that require wide bandwidth and low noise performance.

Features

1. Low supply current – only 1.3 mA/amplifier2. High speed – GBWP 3.2 MHz3. Low input offset voltage – only 2.5 mV4. Low input bias current – only 10 nA5. Low total harmonic distortion (THD)6. Output short-circuit protection7. Internal common-mode feedback removing external components

Application

TL072IDRE4 is used in many audio and instrumentation applications. It is ideal for very low voltage power supplies and low power audio applications, such as portable audio, instrumentation and audio mixing. It can also be used in audio signal routing and mixing. In addition, TL072IDRE4 is a great choice for active filters, voltage controlled oscillators, sample and hold circuits, automatic gain control circuits, modulators and demodulators, voltage to current converters, audio pre-amplifiers, headphone amplifiers and tracking systems.

Working Principle

TL072IDRE4 is a dual-channel JFET input operational amplifier. The JFET input stage provides very low input capacitance and low input bias current. The JFET inputs are internally connected to voltage references, resulting in very low offset voltage.This amplifier runs on single-supply, low-voltage operation with a supply voltage range of 1.35 V to 7 V. It can provide a wide range of gains without the need of external components and the output can swing down to zero volts.Additionally, TL072IDRE4 features three gain stages connected via an intermediate buffer amp stage. This provides a higher gain bandwidth and increased stability. The multiple stages also reduce distortion and noise.TL072IDRE4 also has short-circuit protection built in, allowing it to be used in applications with high output currents. The amplifier is operational up to a temperature of 85°C.

Conclusion

TL072IDRE4 is a low-power, high-bandwidth dual-channel JFET input operational amplifier with multiple gain stages. It is widely used in audio and instrumentation applications due to its low input offset voltage, low input bias current, low THD, wide GBWP and low supply current. It also has built-in output short-circuit protection and can be operated in single-supply, low-voltage operation.
