The ADAS1000 contains different modes of operation, deciding which to use can be a bit confusing, here's a little guidance and also some example calculations in attached excel sheet (see below)

 

Analog Lead mode

  • use for typical ECG lead configuration, creates the analog lead up front before digitization in the ADC, generates LEAD I/II/III and the V wrt WCT
  • has slightly lower noise performance than digital lead mode
  • Preferred mode for normal ECG applications

 

Digital Lead mode

  • use for typical ECG lead configuration. Each channel is digitized by ADC and the lead is calculated after the ADC
  • slightly higher noise performance than digital lead mode

 

Electrode mode

  • use where need to digitize each input individually and not interested in a lead measurement
  • Each channel is digitized wrt VCM_REF
