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.

Who has never experienced oscillations issues when using an operational amplifier? Opampsare often used in a simple voltage follower configuration. However, this is not the bestconfiguration in terms of capacitive loading and potential risk of oscillations.Capacitive loads have a big impact on the stability of operational amplifier-basedapplications. Several compensation methods exist to stabilize a standard op-amp. Thisapplication note describes the most common ones, which can be used in most cases.The general theory of each compensation method is explained, and based on this, specific

Photodiodes can be broken into two categories: largearea photodiodes with their attendant high capacitance(30pF to 3000pF) and smaller area photodiodes withrelatively low capacitance (10pF or less). For optimalsignal-to-noise performance, a transimpedance amplifi erconsisting of an inverting op amp and a feedback resistoris most commonly used to convert the photodiode currentinto voltage. In low noise amplifi er design, large areaphotodiode amplifi ers require more attention to reducingop amp input voltage noise, while small area photodiodeamplifi ers require more attention to reducing op amp inputcurrent noise and parasitic capacitances.

Abstract: We can apply a BiCMOS integrated circuit with only resistors and no transistors to solve adifficult design problem. The mythically perfect operational amplifier's gain and temperature coefficient aredependent on external resistor values. Maxim precision resistor arrays are manufactured together on asingle die and then automatically trimmed, to ensure close ratio matching. This guarantees that theoperational amplifier (op amp) gain and temperature coefficient are predictable and reliable, even withlarge production volumes.

Abstract: Rail splitting is creating an artificial virtual ground as a reference voltage. It is used to set the signalto match the op amp's "sweet spot." An op amp has the most linear- and distortion-free qualities at that sweetspot. Typically, the sweet spot occurs near the center between the single power rail and ground. In the case ofa number of signals, the virtual ground can control channel DC errors when multiplexing or switching thesignals.
