The MAXM86146 is the world’s smallest highly-integrated, optical data acquisition system. It combines Maxim's bestin- class optical biosensing analog front end (AFE) with a powerful Arm® microcontroller unit (MCU) and two high sensitivity photodiodes.

The integrated MCU is an ultra-low-power microcontroller specifically designed for battery-powered devices and wireless sensors. It combines a flexible and versatile power management unit that operates from a single 1.8V supply. It supports I2C communication protocol and is ready to be programmed with the latest firmware and world-class algorithms for wearable applications including pulse heart rate (HR), pulse blood oxygen saturation (SpO2). The integrated algorithms adjust the optical AFE settings to maximize SNR while minimizing power consumption based on activity classification.

The optical AFE has two low-noise optical readout channels. Both channels have independent 19-bit ADCs and an industry-leading ambient light cancellation (ALC) circuit for unparalleled ambient-light rejection in many scenarios. The optical AFE includes three high-current, low-noise LED drivers and operates on a 1.8V main supply voltage and a flexible LED driver supply voltage.

With the addition of external LEDs and an accelerometer (required), a complete system is achieved reducing time to market and simplifying design. This arrangement seamlessly enables customer-desired on-chip processing, resulting in a highly-integrated sensor hub with embedded algorithms.

The MAXM86146 is available in a compact 4.5mm x 4.1mm x 0.88mm, 38-pin OLGA package and operates over commercial temperature range of 0°C to +70°C.
