The AD9225ARSRL is an analog-to-digital converter (ADC) that enables data acquisition and signal processing applications to convert analog signals, such as temperature, pressure, strain, audio, and video into digital signals. It is commonly used in applications that require reliable, high-speed and high-resolution data acquisition. The AD9225ARSRL is a 23-bit low noise, low power, SAR-based AD converter available in a 10 mg, 8-lead TSSOP package.

The AD9225ARSRL features a versatile configuration designed to meet the needs of a wide range of applications. It features a 8-channel simultaneous sampling with an exceptional low noise and low power consumption, making it ideal for applications that involve sensing small fast signals. The device also features an up-to-date 2.4 V to 3.6 V supply voltage range, allowing for universal integration in a wide range of systems. Additionally, the AD9225ARSRL features an on-chip reference, eliminating the need for an external reference, and supports a wide operating temperature range from -40°C to +85°C.

The AD9225ARSRL has a high speed data rate of up to 500ksps, which is advantageous in certain data acquisition applications. It is capable of achieving an input dynamic range of up to +95 dBFS, making it an ideal choice for applications that require high data accuracy. Additionally, the device features an integrated zero-latency track-and-hold function, permitting shorter acquisition times without adversely impacting the device\'s ability to accurately convert the analog signal to digital. Finally, the device also has a 4-bit resolution mode, which enables the device to convert more data faster and more accurately.

The AD9225ARSRL\'s working principle is based on successive-approximation-register (SAR) architectures. The ADC passes the converted digital output sampled each time the analog input value has crossed a reference level with a set resolution. When conversion has been conducted, the digital output registration can also remain in the SAR until it is changed by a subsequent incoming analog signal. This digital output is then latch and forwarded through an output register, eventually producing a corresponding digital output.

The AD9225ARSRL is a feature-rich ADC that is ideally suited for applications involving analog-to-digital conversion. It is the ideal choice for applications that require high-speed data acquisition, low power consumption, low noise, and a wide operating temperature range. The built-in features, such as the 4-bit resolution mode and the integrated zero-latency track-and-hold function, make it an excellent choice for applications that require precise, accurate, and fast data acquisition.
