Design Guide

Low-Cost Blood Pressure and Heart Rate Monitor Reference Design

Description

This is a reference design for a low-cost electronic blood pressure monitor (BPM), or sphygmomanometer, with focus on low-noise performance using both TI's Microcontroller (MCU)-integrated chopping amplifiers and small size external amplifiers. This design targets portable battery-operated devices and showcases how the MSPM0L1306 with integrated precision analog can be leveraged to reduce cost and external components. The designer can easily switch to the included INA350 to evaluate alternative low-cost architectures, and test TI's smallest motor and pump driver, the DRV8210. A GUI is included for testing and evaluation.

Features

  • Ultra-low-power in standby mode for extended battery life
  • Low-cost MCU with integrated INA for size and BOM reductions
  • Supports GUI and Raw Data Readout for ease of algorithm development and post-processing
  • Smallest integrated valve and pump driver design helps in reducing the overall size
  • On-the-fly transition for evaluation of both external INA and MCU-integrated INA
