The MAX8697SEWQ+T is an integrated circuit (IC) component designed for optical sensors applications. It belongs to the MAX8697 series of devices manufactured by Maxim Integrated.
The IC is specifically designed for vital-signs monitoring, offering high accuracy and low power consumption. It integrates several key features that make it suitable for a wide range of wearable health monitoring devices.
One of the main features of the MAX8697SEWQ+T is its optical sensor interface, which allows for non-invasive monitoring of various vital signs. It supports both reflective and transmission-based photoplethysmography (PPG) signals, enabling measurement of heart rate, SpO2 (blood oxygen saturation), and other parameters.
To provide accurate and reliable measurements, the IC component includes advanced signal processing algorithms. These algorithms work in conjunction with the integrated ambient light cancellation technology to filter out noise and external light interference. This ensures high-quality data output even in challenging environments.
Another notable feature is the programmable LED current and pulse width modulation (PWM) control. This allows the device to adjust the LED drive current and pulse width, enhancing measurement accuracy and power efficiency. Moreover, it supports external LED drivers to provide flexibility in the design of the sensor module.
The MAX8697SEWQ+T also includes a low-power microcontroller unit (MCU) with an I2C interface for easy integration into various applications
