Analog to digital converters (ADCs) are electronic circuits designed to convert continuous analog signals to discrete digital signals. The DC1751A-E is an evaluation board chopper-stabilized amplifier designed to demonstrate the performance of the DC1060L-E integrated circuit from Microchip. This board can improve the dynamic accuracy of a precision integrated circuit by using a chopper-stabilized amplifier. This article will cover the application field and working principle of the DC1751A-E evaluation board.The application field for the DC1751A-E board is mainly in low noise and wide dynamic range applications. This board comes with the DC1060L-E integrated circuit, which enables the board with low noise and wide dynamic linearity from 0.3 Hz to 350 kHz. It also offers an extremely accurate and low noise output. This board has a low input bias current and includes an inverting amplifier with a gain of 105 dB or higher. It is suitable for use in a variety of applications, such as medical instruments, telecommunications, optical networks, industrial automation and metrology.The working principle of the DC1751A-E board starts with a chopper-stabilized amplifier. This type of amplifier is used to reduce the offset error and thermal drift of amplifiers, and provide better accuracy and linearity across its wide frequency range. It works by chopping the output of the amplifier and then alternating between two condition. The first condition transfers the entire amplifier with full power. The second condition guides the offset voltage of the amplifier to its output with only a small amount of current. This helps to reduce the total offset error of the amplifier and improve the overall accuracy of the board.The DC1751A-E board also features a voltage reference circuit that enables for a stable reference voltage for the chopper-stabilized amplifier, in order to improve the accuracy even further. Additionally, the board has an integrated temperature compensation circuit, which makes it more flexible and suitable for a wider range of applications.To sum it up, the DC1751A-E chopper-stabilized amplifier evaluation board from Microchip is designed for use in low noise and wide dynamic range applications. It comes with the DC1060L-E integrated circuit, which enables the board with low noise and wide dynamic linearity from 0.3 Hz to 350 kHz. It is also equipped with a voltage reference circuit, temperature compensation circuit, and a chopper-stabilized amplifier. The DC1751A-E is suitable for use in a variety of fields, such as medical instruments, telecommunications, optical networks, industrial automation and metrology.
