HD Medical has created an electronic stethoscope that augments sound with visual displays of heart waveforms. The audio quality is up to 30x better than that of traditional stethoscopes, too. For Arvind Thiagarajan, the company's founder and CEO, this invention is all about helping doctors conduct more accurate initial patient screenings, detect heart conditions like murmurs earlier, and reduce the costs of unnecessary tests. To develop the ViScope stethoscopes, HD Medical needed high-performance, very low-power, and small-footprint ICs. The company found its answers in Maxim's microcontrollers, battery charge management ICs, DC-DC converters, and battery monitors. Read about how Thiagarajan's personal journey with the medical world inspired his interest in developing technologies that assist doctors, and find out how he addressed design challenges with Maxim ICs by reading the HD Medical testimonial.
