Low EMI Isolation for Medical Equipment Applications
July 06, 2011 // Silicon Laboratories // 0 commentsDownload White Paper 311Ko
EMI is especially problematic in medical systems that acquire low-amplitude signals, such as electrocardiographs (ECGs), where signals collected from patients can range from 400 µV to 5 mVpk with 3 dB corner frequencies at 0.05 and 100 Hz. The trend towards higher-frequency, lower-power medical systems complicate EMI management by emitting broader bandwidth RF noise at higher energy levels. Find out what you need to know about EMI and how to minimize the effects in medical electronic applications using digital isolation.

This month, Trinamic Motion Control is offering you to win one of four TMCM-1043 development kits for its highly integrated, NEMA 17-compatible TMCM-1043 stepDancer stepper motor module.
Offering designers an easy-to-use PC-based GUI that allows one-click modification of motor drive current, micro-stepping and other key parameters, the intuitive kits are custom designed and developed for direct mounting on a NEMA 17 motor. Pre-programmed and pre-configured with all operating parameters to support standard 1.5A (peak) motors, the TMCM-1043 board uses Trinamic´s single-axis TMC2660 stepper motor driver IC, which integrates a motor pre-driver and power MOSFETs.
