App note: The effect of pan material in an induction cooker

A good read on induction cooker and the effects of pan material used, app note(PDF) from ON Semiconductors. Induction heating is a well established method of generating heat in metal goods and has been used for decades. The induction cooking market is well established, but little has been written regarding the properties and interactions of […]

App note: EMI and ESD filtering of audio interconnects

App note(PDF) on NUF2441FC EMI and ESD filter chip from ON Semiconductor. The continued ever-increasing integration of more functions into personal electronic devices such as cell phones has made electronics manufacturers demand more integrated functions to reduce part count and save board space. Cell phone manufacturers have also driven component manufacturers to produce more efficient […]

App note: Analog switches solve many problems within a cell phone

Applications(PDF) of analog switches inside a cell phone by ON Semiconductor. Analog switches have been available since the 60’s as a component for systems designers. With the advent of ASICs and ASSPs, many designers have not experienced the real value of these devices. Today’s designers may be familiar with the venerable MC14066, a workhorse that […]

App note: Minimizing the temperature dependence of digital potentiometers (POTs)

An app note from ON Semiconductors. The digital POT has two temperature dependent parameters, the TC of the end-to-end resistance RPOT and the ratiometric TC. The temperature dependence of the parameters of an analog circuit using a digital POT is reduced if the performance of the circuit is shifted from the TC of the end-to-end […]

App note: An introduction to LDO early warning function

Supervisory reset delay prevents premature power fail resets, App note from ON Semiconductor. In today’s world of high speed, high power processors, new demands have been placed on the power source regulator. One example is the need to inform the processor in advance of an impending drop in supply voltage below a critical value. A […]
