Linear-Comparators broadly encompass a range of analog devices that are used to interface analog signals from one environment to another. In particular, AD790AQ is a popular Linear-Comparator used for a variety of applications. This article will discuss the applications and working principle of the AD790AQ.

The AD790AQ is a dual-channel rail-to-rail input/output linear-integrated differential comparator. It has many advantages over analog comparators, such as low power consumption, low distortion, adjustable hysteresis, and low offset voltage. This makes the AD790AQ an ideal choice for precision analog comparison in a variety of applications, including analog-digital conversion, motor control, and audio applications.

In terms of its application field, the AD790AQ is commonly used in audio programs due to its low distortion and adjustable hysteresis. Specifically, the adjustable hysteresis in combination with the low distortion makes it suitable for audio applications requiring linear speed and accuracy. Additionally, its low offset voltage makes it suitable for low distortion applications, such as audio frequency detection, audio equalization, and speaker protection.

The AD790AQ is also useful for motor control applications. It is capable of providing a highly linear response that is essential for achieving motor control specific performance objectives. It has low internal power consumption, meaning that it is capable of high efficiency and low power consumption when compared to other analog comparators. Additionally, its differential inputs allows for symmetrical signal transitions in motor control applications.

The AD790AQ is also used in analog-to-digital conversion applications. It is able to compare input signals with a reference voltage and output a digital signal depending on the input thresholds. This makes it an ideal choice for applications requiring precision and accuracy in analog-to-digital conversion. Additionally, its low power consumption and low distortion makes it suitable for low noise applications, such as medical applications.

Finally, the working principle of the AD790AQ can be described as follows. Its inputs can be divided into two categories, inverting and non-inverting inputs. The non-inverting input is connected to a reference voltage, while the inverting input is connected to the signal to be compared. When the non-inverting input is higher than the inverting input, the output of the comparator is driven high. Conversely, when the non-inverting input is lower than the inverting input, the output of the comparator is driven low.

In summary, the AD790AQ is a popular Linear-Comparator with a wide range of applications. It is suitable for audio applications due to its low distortion and adjustable hysteresis, motor control applications due to its low power consumption and differential inputs, and analog-to-digital conversion applications due to its ability to compare input signals with a reference voltage and output a digital signal when thresholds are exceeded. The working principle of the AD790AQ can be described as having two inputs, one connected to a reference voltage and the other connected to the signal to be compared, and the output of the comparator being driven high when the non-inverting input is higher than the inverting input, and driven low when it is lower.
