lm324 quad comparator

LM324, LM324A, LM224, LM2902, LM2902V, NCV2902 Single Supply Quad Operational Amplifiers The LM324 series are low−cost, quad operational amplifiers with true differential inputs. They have several distinct advantages over standard operational amplifier types in single supply applications. The quad amplifier can operate at supply voltages as low as 3.0 V or as high as 32 V with quiescent currents about one−fifth of those associated with the MC1741 (on a per amplifier basis). The common mode input range includes the negative supply, thereby eliminating the necessity for external biasing components in many applications. The output voltage range also includes the negative power supply voltage. Features • Short Circuited Protected Outputs • True Differential Input Stage • Single Supply Operation: 3.0 V to 32 V • Low Input Bias Currents: 100 nA Maximum (LM324A) • Four Amplifiers Per Package • Internally Compensated • Common Mode Range Extends to Negative Supply • Industry Standard Pinouts • ESD Clamps on the Inputs Increase Ruggedness without Affecting Device Operation • NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC this IC can be used in various electronics circuits like voltage comparator, triangular wave generator(pwm), voltage monitor(low voltage check), line following robot etc.

Aakriti 2014 event organised by kathmandu engineering college kalimati

Aakriti2014 was the event recently organised by kathmandu engineering college kalimati kathmandu. the event was 3 days long and held successfully by the college of all department. Also there was a competition of various field of engineering. students and professionals of many fields were present there to show their project and prototype. cosmos college of management and technology was the only college who participated there from other university of the college in Hardware competition. The Team of students of second semester of electronics and communication engineering made a very smart project named smart representing home automation and security system under the supervision of cosmos electronics research team(CERT) and won the second prize there. the first prize was given for Robotic hand from the college of organiser. the participants from the cosmos college under the team CERT were 1. sunil thapa 2. samrat koirala 3. ganesh bhushal 4. ramita shah 5. srijana bohara
many many congratulation for the second prize winner of the event.
