OPA552UA

Instrumentation, OP Amps, Buffer Amps

The OPA552UA operated amplifier is a reliable, high-performance tool that can be used in a variety of applications. It is an integrated circuit (IC) device, built with several transistors and other circuit elements, configured to amplify signals and power supplies. The OPA552UA is a wideband, low noise, high speed amplifier designed to provide a wide frequency range of operation and a high gain impedance converter.

Application Field

The OPA552UA is ideal for a wide range of applications. It can be used in broadcast and audio applications, as well as in audio amplification, energising applications and instrumentation. It is commonly used in mixers, power amplifiers, weigh scales, sensors, antennas and acoustic transducers such as microphones, receivers and speakers. It can be used as an input module to process signals before they are provided to a system. It can also be used to drive high-current output stages and to provide higher voltage gains.

Working Principle

The OPA552UA amplifier operates on a classic differential amplifier circuit, with a single input and two outputs. The two output signals are referred to as the true and complementary output. The circuit has two input terminals and two output terminals, connected to two transistors that convert the input signal into two output signals, one inverting and one non-inverting. The output signal can be changed using the two adjustable parameters, gain and offset.

The OPA552UA amplifiers offers high distortion levels and its low noise floor allows it to reproduce signals with minimal interference. The high slew rate and low propagation delay of the amplifier enable it to reproduce high-speed signals accurately. The overall performance of these amplifiers can be fine-tuned by changing the quiescent current and the gain and offset of the amplifier.
