Maxim Integrated MAX86141ENP+T Optical Sensor

The Maxim Integrated MAX86141ENP+T is a highly integrated, low-power optical sensor designed for precision heart rate monitoring and pulse oximetry. This compact sensor module is an ideal solution for wearable devices, fitness trackers, and smartwatches due to its small form factor and high performance in biometric sensing applications.

The MAX86141ENP+T combines two LEDs, a photodetector, and advanced analog front-end (AFE) electronics in a single package. This integration facilitates the design of compact and power-efficient applications without sacrificing accuracy and reliability. The AFE includes a programmable current for the LEDs, a high dynamic range, and a high-resolution ADC, ensuring precise measurement of the photodetector's signal.

One of the key features of the MAX86141ENP+T is its ability to operate in both single and dual-LED mode. This flexibility allows designers to choose the most appropriate configuration for their specific application. In dual-LED mode, the sensor can perform simultaneous green and IR LED measurements, which is essential for accurate pulse oximetry readings.

Moreover, the sensor supports a range of data rates and includes a built-in FIFO memory, which can store up to 32 samples. This feature reduces the demand on the host processor, as it can retrieve data from the FIFO at its convenience, leading to lower system power consumption.

The MAX86141ENP+T operates on a supply voltage of 1.8V for the analog supply and 1.2V to 3.6V for the digital supply, which makes it compatible with most low-power MCUs and processors used in wearable devices. Additionally, it communicates with the host processor via a standard I2C interface, simplifying integration into existing designs.

With its low power consumption, high integration, and advanced features, the Maxim Integrated MAX86141ENP+T optical sensor is an excellent choice for developers looking to incorporate reliable heart rate and SpO2 monitoring into their health and fitness applications.
