HTC Incredible’s real price tag: $163.35

iSuppli's Teardown Analysis Service conducted a study of the cost of materials for the HTC Incredible. The total was $163.35 for the parts and electronic components used to build the smartphone. Nearly 20% of the cost of the handset is from the processor which cost $31.40. Right behind the processor was the display and touch screen which is manufactured by Samsung. The display, which is an advanced Active Matrix Organic Light Emitting Diode (AMOLED), cost $31.20. In third place was the memory Read more [...]

Low Power Quad Op Amps – LM324AD of the LM324 Series

The LM324 series consists of four independent, high-gain, internally frequency-compensated operational amplifiers designed specifically to operate from a single power supply over a wide range of voltages. In the linear mode, the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage. The unity gain crossover frequency and the input bias current are temperature-compensated. The Read more [...]

Op Amps – Then and Now

Op Amps – Then and Now Op amp is the commonly used name for operational amplifiers, which are widely used electronic components. Op amps are often seen on many surface equipment designs and logging tools. The name ‘operational amplifier’ comes from the use of such high gain amps in performing mathematical operations for analog computer operations and is said to have been coined in 1947. A lot of study was done in the field and the initial operational amplifiers, based on Read more [...]
