Cart ECG (electrocardiogram) with Bluetooth Low Energy Reference Design
(ACTIVE) TIDA-ECG-BLUETOOTH-LOW-ENERGY-REFERENCE-DESIGN
View the Important Notice for TI Designs covering authorized use, intellectual property matters and disclaimers.
Description
The heart of this reference design is the Analog Front End – ADS1293 from Texas Instruments. It provides 3 high resolution digital ECG channels with simultaneous pace output. The ADS1293 consumes low power of 0.3mW/channel and has a low input referred noise. Another aspect of this reference design is the wireless feature via Bluetooth low energy SOC. The CC2541 has a built in microcontroller (8051) that interfaces with ADS1293 and transmits the ECG data to a smartphone or a tablet. The reference design also incorporates a low-cost pcb trace antenna for the Bluetooth Low Energy.
