Data Acquisition - Analog to Digital Converters (ADC)Analog to Digital Converters (ADC) are electronic components that are used to convert analog signals into digital representations. The AD9248BSTZ-20 is a low power, high speed 8-bit Analog-to-Digital Converter (ADC) designed for high dynamic range signal acquisition and signal processing applications. It provides simultaneous sampling, low noise and high signal to noise ratio (SNR) performance.The AD9248BSTZ-20 is capable of conversion rates up to 1 million samples per second (Msps). It is constructed as a dual-channel parallel-input ADC, with both single-ended and differential input options, and supports direct I/O connection with microcontrollers, FPGAs, and other devices. Additionally, it features three low-power modes, which make it an ideal solution for low-power use cases.The device features a single-ended input for each channel and differential mode for inputs A and B. Each input offers an independent signal path with an input range of ±1.8V, and a linearity of 0.2LSB max. The ADC also features a low power off mode and two low power modes, which reduce the device power consumption even further for battery-powered applications.The AD9248BSTZ-20 is suitable for a variety of applications, such as medical imaging, battery-operated instrumentation, ultrasound, ultrasound imaging, 4G/LTE radio base station processing, telecom, and instrumentation. It has the flexibility to operate in both degraded and non-degraded modes, making it ideal for applications with strict dynamic range requirements. The ADC also integrates a high speed clock generator that supports both fixed frequency and variable frequency modes, which makes it suitable for data acquisition in measurement and communications.The AD9248BSTZ-20 has a typical dynamic resolution of 7.8 effective number of bits (ENOB) and a maximum conversion speed of 1 million samples per second (Msps). The device also features an integrated output data comparator, which allows for data comparison without the need for a separate analog circuit. Additionally, it features an internal digital calibration loop to minimize offset, gain and linearity errors. The device is built using the HV-CMOS process and encapsulated in a 48-pin, QFN 6mm x 6mm package. It is capable of functioning in temperatures of up to +125°C and provides a typical power consumption of just 3.9 mW/Msps, making it an ideal solution for battery-powered applications.In summary, the AD9248BSTZ-20 is a low power, high speed 8-bit Analog-to-Digital Converter (ADC) designed for high dynamic range signal acquisition and processing applications. It features simultaneous sampling, low noise, high signal to noise ratio (SNR) performance and low power modes, making it suitable for a variety of data acquisition and communication applications. Moreover, it has an integrated clock generator that supports both fixed frequency and variable frequency modes, ensuring its flexibility for different applications. And its low power consumption makes it suitable for small, battery-powered devices.
