The AD8564AR-REEL is a high-precision, low-power, low-offset operational amplifier from Analog Devices. This device falls into the category of linear comparators, which are integral to many analog applications. This article will discuss the application fields and working principles of the AD8564AR-REEL.

Analog Devices’ AD8564AR-REEL is well suited for automotive, consumer, and industrial applications. Its low power consumption coupled with fast settling time make it ideal for AC/DC signal conditioning, data acquisition, and active filtering. The device’s low offset-voltage and low bias-current, along with its dual external current trimming pins can allow designers to adjust the offset voltage on the fly and in the field.

The AD8564AR-REEL is constructed with a single-channel amplifier, featuring high common-mode rejection and low offset voltage over temperature. The device has a minimum CMRR of 65dB, ensuring high accuracy and precision in many applications. The device also features a wide supply voltage range from 2.7V to 36V, making it suitable for a range of powered environments.

These features allow the AD8564AR-REEL to excel in applications that require fast settling times and low power consumption, such as active-RC filters. The device can also be configured to provide a wide range of linear output current responses, allowing designers to configure it for specific jobs where precision and accuracy are of the utmost importance.

The AD8564AR-REEL works on a basic principle of comparing two analog signals. It will take the difference between two inputs and output a voltage or current corresponding to the difference. This voltage will be referenced by a ground or supply terminal of the amplifier, depending on the configuration. The device has two non-inverting and one inverting input, as well as an output connection for the resulting voltage or current. The AD8564AR-REEL will only output a voltage if the difference between the two input signals is greater than the hysteresis voltage of the device, which is typically around 0.1V.

The AD8564AR-REEL is a great choice for applications requiring high accuracy, low power consumption, and low offset voltage. The device can be used for AC/DC signal conditioning, data acquisition, active filtering, and other related applications. The device’s dual external current trimming pins and wide supply voltage range make it suitable for many powered environments. The device’s compare algorithm is simple, yet effective in providing fast settling times and high levels of accuracy to any application.
