Maxim claims that its in-ear heart-rate monitor and pulse oximeter is the smallest fully integrated solution that delivers heart-rate and SpO2 measurements from hearables and wearables.

The MAXM86161 has an integrated analogue front-end (AFE) which eliminates the additional AFE typically needed to procure a separate chip and connect to the optical module.

The MAX30208 digital temperature sensor delivers clinical-grade temperature measurement accuracy (±0.1°C) with fast response time to changes in temperature.

It also meets the power and size demands of small, battery-powered applications such as smartwatches and medical patches.

It simplifies the design of battery-powered, temperature-sensing wearable healthcare applications. Easier to use than competitive offerings, it measures temperature at the top of the device and does not suffer from thermal self-heating like competitive solutions.

MAX30208 is compatible with up to four I2C addresses to enable multiple sensors on the same IC bus. It  can be attached to either a PCB or a flex printed circuit (FPC).
