The operational amplifier – or “op amp” for short – is a common building block in analog electronics. Whether you’re a professional electronics designer or just getting started, it is likely you’ve used an op amp in your designs. Invented in 1941 by Karl D. Swartzel Jr. of Bell Labs, the op amp was originally […]
OriginGPS has announced its first dual-frequency GNSS module, the ORG4600-B01, which will enable customers to build systems with sub-1m accuracy without implementing external components. by Jean-Pierre Joosting @ www.mwee.com Measuring just 10- x 10-mm, the ORG4600-B01 module supports L1 + L5 GNSS reception with one RF port, enabling the use of a low-cost, dual-band antenna delivering

A microcontroller, a digital device, can read, execute and transmit only digital signals. On the contrary, the outputs of the most of the transducers are analog in nature. Thus it is hard to interface these transducers directly with controllers. Analog-to-digital convertor (ADC) ICs are one way to make the analog input compatible with the microcontroller. Using
