Analog Devices (ADI) has launched a low-power, high-performance analog front end (AFE) for small, wearable devices that is expected to help develop battery-powered devices that assess patient health.

Analog Devices (ADI) today announced the availability of the MAX30009 low-power, high-performance BioZ analog front end (AFE), which enables smaller size and longer life of bioimpedance (BioZ) remote patient monitoring (RPM) devices.

The MAX30009 BioZ AFE is highly integrated and is 30% smaller than competing products, enabling smaller measurement devices for improved patient comfort and consuming 62% less power than competing products.

It is also a high-performance device that supports simultaneous measurement of I and Q channels, 2-electrode and 4-electrode configurations, sample rates of 16sps to 4ksps, and a wide frequency range of 16Hz to 891KHz.

“For developers of small, battery-powered wearable devices that require continuous operation, this chip-on-AFE provides clinical-grade vital sign measurements required for bioimpedance analysis in wearables and medical-grade patches to assess patient health,” ADI said.
