ADS7800KU Description

The ADS7800KU is a high-performance, 12-bit analog-to-digital converter (ADC) designed by Texas Instruments, a leading manufacturer in the electronics industry. This IC is part of the Data Acquisition ICs category and is housed in a 24-pin SOIC package. The ADS7800KU features a single A/D converter with a sampling rate of 333,000 samples per second (333k SPS), making it suitable for applications requiring high-speed data acquisition. The device employs a successive approximation register (SAR) architecture, which ensures accurate and efficient conversion of analog signals to digital data.

The ADS7800KU is equipped with a single-ended input type, allowing for straightforward integration into various electronic systems. It operates with a 5V digital supply voltage and includes an internal reference type, which enhances the accuracy and reliability of the conversion process. The data interface is parallel, facilitating easy communication with microcontrollers and other digital systems. The device is REACH unaffected and ROHS3 compliant, ensuring it meets environmental and safety standards.

The ADS7800KU has a moisture sensitivity level (MSL) of 3, which means it can be stored for up to 168 hours before assembly without additional precautions. This feature is particularly beneficial for surface-mount applications, as it reduces the risk of moisture-related issues during the manufacturing process. The product is currently in the "Last Time Buy" status, indicating that it is a legacy product with limited availability.
