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 illustrates the flexibility of the MAX7060 ASK/FSK transmitter. While the currently available evaluationkit (EV kit) has been optimized for the device's use in a specific frequency band (i.e., 288MHz to 390MHz), this document addresseshow the EV kit circuitry can be modified for improved operation at 433.92MHz, a frequency commonly used in Europe. Twoalternative match and filter configurations are presented: one for optimizing drain efficiency, the other for achieving higher transmitpower. Features and capabilities of earlier Maxim industrial, scientific, and medical radio-frequency (ISM-RF) transmitters areprovided, allowing comparison of the MAX7060 to its predecessors. Several design guidelines and cautions for using the MAX7060are discussed.
