Abstract: This application note describes the essential workings of an electrocardiogram (ECG). It discussesfactors that disrupt the ECG signals and make reliable, highly-accurate electrical characterization difficult. Theindustry-standard solution for ECG electrical characterization, which uses an analog front-end and ADCcombination, is explained. The ARTicle then introduces the MAX11040 simultaneous-sampling, sigma-deltaADC as a compelling, highly integrated solution that eliminates the need for the AFE, and saves both spaceand cost for the application.

Abstract: This application note describes how sampling clock jitter (time interval error or "TIE jitter") affectsthe performance of delta-sigma digital-to-analog converters (DACs). New insights explain the importanceof separately specifying low-frequency (< 2x passband frequency) and high-frequency or wideband (> 2xpassband frequency) jitter tolerance in these devices. The ARTicle also provides an application example ofa simple highly jittered cycle-skipped sampling clock and describes a method for generating a properbroadband jittered clock. The document then goes on to compare Maxim's audio DAC jitter tolerance tocompetitor audio DACs. Maxim's exceptionally high jitter tolerance allows very simple and low-cost sampleclock implementations.

Abstract: It is incredible how many programmable logic controls (PLCs) around us make our modern life possible and pleasant.Machines in our homes heat and cool our air and water, as well as preserve and cook our food. This tutorial explains the importanceof PLCs, and describes how to choose component parts using the parametric tools on the Maxim's website.A similar version of this ARTicle was published February 29, 2012 in John Day's Automotive Electronic News.

Abstract: This ARTicle discusses application circuits for Maxim force/sense digital-to-analog converters (DACs). Applications include:selectable fixed-gain DAC, programmable gain DAC, photodiode bias control, amperometric sensor control, digitally programmablecurrent source, Kelvin load sensing, temperature sensing, and high current DAC output. A brief description of the various DAC outputconfigurations is also given.

Abstract: Using a wafer-level package (WLP) can reduce the overall size and cost of your solution.However when using a WLP IC, the printed circuit board (PCB) layout can become more complex and, ifnot carefully planned, result in an unreliable design. This ARTicle presents some PCB designconsiderations and general recommendations for choosing a 0.4mm- or 0.5mm-pitch WLP for yourapplication.

Abstract: There are differences between the operation of low-frequency AC transformers and electronic transformersthat supply current to MR16 lamps, and there are also differences in the current draw for MR16 halogen lamps andMR16 LED lamps. These contrasts typically prevent an MR16 LED lamp from operating with most electronictransformers. This ARTicle explains how a high-brightness (HB) LED driver optimized for MR16 lamps will allow LEDlamps to be compatible with most electronic transformers.A similar version of this ARTicle appeared on Display Plus, July 7, 2012 and in German in Elektronikpraxis, October 1,2012.
