Introduction 

General Product Information 

The RT1025 is an integrated AFE solution for Heart-Rate monitoring and measurements. The RT1025 integrates low 

noise  voltage  and  current  sensing  channels  and  is  capable  of  sensing  ECG  (Electrocardiography)  and  PPG 

(Photoplethysmography) simultaneously. The RT1025 has > 100dB dynamic range and can sense pulses accurately 

by  de

tecting  the  heart’s  electric  signals.  The  sampling  rates  of  the  high-precision  voltage  and  current  sensing 

channels  in  the  RT1025  are  configurable  between  64  to  4kHz.  The  RT1025  solution  need  only  few  discrete 

components and is easy to use for low-power medical ECG/PPG, sports, and fitness applications. With high levels 

of integration and high-precision voltage and current sensing channels, the RT1025 solution is suitable for scalable 

medical  instrumentation  systems.  The  RT1025  is  available  in  a  3.1mm  x  3.4mm,  41-Ball,  0.4mm  pitch, WL-CSP 

package.   

The  Cardio  EVK  is  an  Android  APP  to  evaluate  RT1025  performance  with  the  Cardioid  evaluation  board.  The 

evaluation board includes the RT1025 together with the BLE SiP and PPG modules to quickly evaluate the operation 

and performance of the RT1025. The evaluation board number is PCB106_V1. For more information, please find the 

related datasheet or application notes from Richtek website.
