The AS339AMTR-E1 is a specialized semiconductor device in the category of Linear-Comparators. Such comparators are typically used to compare two input signals and output electric signals based on their relative magnitudes, allowing for an amplification of one signal or various access points based on the relative difference between the two signals. The AS339AMTR-E1 was developed to offer similar functionality, while also providing additional electronic input and output functions.

Overview

The AS339AMTR-E1 operates as an amplifier and comparator circuit which compares two analog signals and then drives output signals accordingly. This makes the device well suited for monitoring two or more signals in order to determine the presence and absence of electronic signals, as well as providing active control of outputs based on these distinctions. The device is specialized to operate with comparators of non-equal amplitudes, and the differential gain for the input signals can reach up to 200dB.

The AS339AMTR-E1 is available in a variety of packages and configurations, some with enhanced features and others with a more general purpose design. Regardless of the specific package and configuration, the device is manufactured in a durable plastic housing and uses power from a wide range of standard supply voltages. This allows for easy integration and extended service in many commercial and industrial applications.

Application Fields

The AS339AMTR-E1 is well suited for use in a variety of commercial and industrial applications. It can be used as a threshold detector, amplitude limiter, RF signal monitoring device, high-performance comparator, or discriminator. Many of its primary functions involve comparing two or more low-level signals in order to detect the presence or absence of specific signal types, whether they be acoustic, RF or other types. These signals can then be monitored and used to control other outputs or systems via the device.

The device is commonly used in audio applications, monitoring and comparing levels of signals to detect for the presence and strength of particular audio signals. It is also used for monitoring acoustic frequencies in speech recognition applications and in noise cancellation systems, helping to further control these systems via variable gain stages. With the accuracy and low-noise performance offered by the AS339AMTR-E1, it is an ideal choice for many types of audio applications.

In addition to audio applications, the device is also well suited for industrial and medical applications. It is often used for measuring differences between two or more signals for monitoring purposes, such as tracking temperatures of multiple points in a system. Furthermore, its low-noise performance is suitable for monitoring and comparing high-fidelity signals in medical MRI and CT scanning systems.

Working Principle

The AS339AMTR-E1 operates by comparing two or more input signals and outputting electric signals based on their comparison. It uses a transimpedance amplifier consisting of an input stage connected to two pairs of field effect transistors (FETs). One of these pairs is connected in parallel, while the other is connected in series. The two FETs on one side of the circuit will generate either positive or negative potentials, depending on the properties of their respective signal sources, while the other two FETs will generate respective opposite potentials based on the same sources.

These potentials are then combined and amplified using an integrating input stage, in which the signal is amplified and the output level is maintained for a certain period of time. When the signal crosses a certain threshold, the comparator produces an output signal, depending on the level of the respective potentials. This output signal is then used to control a load or to activate another application.

Conclusion

The AS339AMTR-E1 is a specialized Linear-Comparator device, designed to compare and monitor two or more input signals. Its comparator circuit operates with a differential gain of up to 200dB, allowing for accurate readings of low-level signals. The device is suitable for many applications, particularly audio and medical, as it can precisely compare signals and control outputs accordingly.
