It is a delta-sigma ADC that works on the concept of delta-sigma modulation and is capable of working with a wide range of input power signals. This article will discuss the application field and working principle of the AD9625BBPZ-2.5.

Application Field of AD9625BBPZ-2.5

The AD9625BBPZ-2.5 is a monolithic device, which is capable of providing 16-bit resolution with a maximum sampling rate of up to 250-mega sample per second. It is mainly used in data acquisition applications where high accuracy and precision measurements are required. Due to its wide input power range, it is well-suited for applications that require a large range of voltage and power signals, such as low-noise amplifiers (LNA), high-precision mass Flow Controllers (MFCs), Direct Digital Synthesizers (DDSs), and temperature controllers.

The AD9625BBPZ-2.5 also offers a variety of features such as programmable input range, very low power consumption, wide voltage swing, and programmable gain. These features make it suitable for applications that require extremely low-noise signals and high-resolution measurements, such as in medical imaging, automotive testing, instrumentation, and industrial applications.

Working Principle of AD9625BBPZ-2.5

The AD9625BBPZ-2.5 is based on the concept of delta-sigma modulation. It uses a delta-sigma modulator to convert the input analog voltage into a digital code. The modulator works on the principle that the amplitude of the input signal is converted into a sequence of discrete binary numbers. The binary numbers are then quantized and oversampled to produce a digital output. The output digital code is then used to obtain a digital representation of the input signal.

The AD9625BBPZ-2.5 utilizes a delta-sigma modulator with an order of 4, which is capable of providing a resolution of up to 16 bits. The modulator also provides a wide input range of up to 5 volts and a very low noise figure, allowing the device to process signals from a wide range of source gains and levels. The ADC also includes a programmable gain amplifier (PGA) to further increase the accuracy and resolution of the output signal.

The AD9625BBPZ-2.5 also includes a variety of features such as adjustable threshold levels and programmable conversion modes, which further enhance its performance. The adjustable threshold levels allow the user to adjust the conversion rate depending on the application, while the programmable conversion modes enable the user to select the type of output code they require.

Overall, the AD9625BBPZ-2.5 is a reliable, high-precision device suitable for various data acquisition applications. Its wide input power range and low power consumption make it a great choice for applications that require high accuracy and precision, such as medical imaging, automotive testing, instrumentation, and industrial applications.
