Maxim Integrated – MAX30110/2: Optimized Pulse-Oximeter and Heart Rate AFE for Wearable Health

FTMFeb2018-AS-AC-MaximIntegratedMAX30110-tile-200x200

The MAX30110/2 is a family of complete optical pulse oximetry and heart rate detection integrated analog front-end. The devices integrated a high-resolution, optical readout signal-processing channel with built-in ambient light cancellation, as well as high-current LED driver DACs, to form a complete optical readout signal chain. With external LED(s) and photo diode(s), the MAX30110/2 offers […]

Maxim Integrated – MAX14874: 4.5V to 36V Dual Relay/ Valve/Motor Driver

FTMFeb2018-AS-AC-MaximIntegratedMAX14874-tile-200x200

The MAX14874 dual push-pull driver provides a small and simple solution for driving and controlling relays and valves with voltages between 4.5V and 36V. It is also designed to drive brushed DC motors. Separate COM pins allow monitoring of individual driver load currents. Peak currents up to 2.5A ensure for PWM controlled large motor torque. […]
