ADS1298IPAG FAQ
What's the difference between ADS1298IPAG and ADS1298IPAGR?
The two ICs chips assure the highest reliability and consistent performance. Do you know the difference between ADS1298IPAG and ADS1298IPAGR? Some of the parameters are completely independent. But the ADS1298IPAG is identical to the ADS1298IPAGR in operating temperature and number of channels. Except that the ADS1298IPAG has TQFP64 packaging instead of tape&reel packaging.
What's the function of the ADS1298IPAG?
A semiconductor device called an Analog Front-End (AFE), which consists of analog amplifiers, op amps, filters, and integrated circuits, is used for signal conditioning. This adaptable functional block is used to connect to several types of sensors.
How to choose an analog front end(AFE) for imaging?
The choice of an AFE for an imaging application depends on many factors, including the type of sensor used, dynamic range, resolution, speed, noise, and power requirements. The most important factor need has driven IC manufacturers to higher levels of circuit integration in order to reduce the size and cost of camera components. Because Camera manufacturers continually need to create higher-performance cameras at lower costs in order to remain competitive.
