The op-amp is basically a differential amplifier having a large voltage gain, very high input impedance and low output impedance. The op-amp has a “inverting” or (-) input and “noninverting” or (+) input and a single output. The op-amp is usually powered by a dual polarity power supply in the range of +/- 5 volts […]

After a period of rapid growth, the CMOS image sensor market has lost steam.
Micron Technology Inc., the world’s largest supplier of CMOS image sensors, could be in the process of spinning off that business amid a slump in the sector, according to recent reports.
It’s also been a topsy-turvy period for OmniVision, Samsung, STMicroelectronics, Toshiba and […]

While ZigBee itself is not new, having been officially ratified as a standard on Dec. 14, 2004, what is new is that certification of products based on this specification are now under way. The promise of ZigBee-compliant products hitting store shelves later this year now looms large. With ZigBee poised to reach this next major […]

The ADS-939 sampling ADC from C&D Technologies is a fully integrated data acquisition system that gives true 16-bit resolution performance at a 10 MHz sampling rate over the entire operating temperature range, up to full military. The functionally complete design requires no external components and is housed in a small, high reliability, hermetically sealed, 40-pin […]

Most audio system design engineers are well aware of the power-efficiency advantages of Class D amplifiers over linear audio-amplifier classes such as Class A, B, and AB. In linear amplifiers such as Class AB, significant amounts of power are lost due to biasing elements and the linear operation of the output transistors. Because the transistors […]
