ADS7822EB/2K5 Data Acquisition - Analog to Digital Converters (ADC)

The ADS7822EB/2K5 is a high-performance, high-speed, low-power analog-to-digital converter (ADC). It is designed to convert analog signals into digital signals, while consuming extremely low power. The device has an 8-Bit resolution, a low-noise digitizer, and an oscillator and scaler. In addition, it is available in a 28-pin QFN, a 24-pin TQFP, and a 24-pin DIP package.The ADS7822EB/2K5 has a low-noise, single channel analog input, allowing it to capture and digitize high-amplitude signals without introducing significant distortion. Additionally, it has a programmable gain amplifier (PGA) supported by a low offset and high linearity. The on-chip 5-pole low-pass filter makes it ideal for noise-sensitive applications.The ADS7822EB/2K5 also has a high-speed, 8-bit, 10-MHz A/D converter. It can sample and digitize the input analog signal and convert it into digital form. This makes it ideal for applications where high data rates are required, such as digital signal processing systems and communications.The ADS7822EB/2K5 also features a digital-output phase-locked loop (PLL) which provides clock frequencies up to 10MHz. The PLL update rate is programmable using the on-chip oscillator and the resulting frequencies can be configured for the various operating modes. The ADS7822EB/2K5 also provides a 2-fold digital-output synchronous serial data transfer. It allows for simultaneous communication with multiple microcontrollers simultaneously, as well as parallel input data capture. The data transfer protocol also supports one-shot command, which provides the ability to send a single command and then receive a response in one clock cycle.Finally, the ADS7822EB/2K5 has an internal power-on reset and programmable power-down function. This is ideal for low-power applications, providing a way to shut the chip down when it is not in use, conserving power and extending battery life.Overall, the ADS7822EB/2K5 is a high-performing, low-power device designed for applications such as medical instrumentation, digital signal processing systems, portable communications, portable audio and video equipment, radar systems, and image capture. Its combination of single-channel high-amplitude, low-noise analog digitizing; high-speed, 8-bit, 10-MHz A/D conversion; digital-output synchronous serial data transfer; and programmable power-down functions make it an excellent choice for these applications.
