Difference Amplifier uses Digital Potentiometers: 05/30/02 EDN Design Ideas / (added 1/05) You sometimes
need to measure a small signal in the presence of a large common-mode signal. Traditional instrumentation amplifiers that use two or three op amps in their internal structure find common use
in these applications. The circuit in Figure 1 presents an alternative approach that is useful when low cost and low drift are important, but when you don't need high precision....
Digital Camera Interface: project shows how a CMOS ‘Camera On a Chip’ image sensor can be interfaced to an XSA-100 Board
through an I2C bus. The pixel data is buffered in the XSA-100 SDRAM and is then uploaded through the parallel port to be displayed on a PC. (added 4/02)
