MAX86150 – Integrated Electrocardiogram (ECG) and Photoplethysmogram (PPG) Bio-Sensor for mobile health monitoring
Maximum Integrated has launched a new bio-sensor which can measure both PPG and ECG as a single package. This sensor is aimed to be used in portable mobile devices like Smart phones, Laptops, Tablets etc. Hence it has been designed in s small form factor and consumes very less power. The sensor also claims to be highly accurate and FDA certifiable. IT has an integrated electrocardiogram, pulse oximeter, heart rate monitor sensor module. It includes internal LEDs, photodetectors, IR sensor and low-noise electronics with ambient light rejection.
The MAX86150 operates on a 1.8V supply voltage with a separate power supply for the internal LEDs. Communication to and from the module is entirely through a standard I2C-compatible interface. The module can be shut down through software with near zero standby current, allowing the power rails to remain powered at all times.
Features of MAX86150:
- Operating Voltage: 1.8V
- Supply Current: 750uA (max)
- Shutdown Current: 0.7uA
- Continuous Power Dissipation: 440mW
- Interface: I2C
- Accuracy: 136dB
- Dimension: 3.3mm x 5.6mm x 1.3mm (22-pin)
- Package: 22 OLGA
