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. […]

Maxim Integrated — PMICs for Hearables: Lowest Standby Power and High Efficiency at Less Than Half the Size

FTMJan2018-AS-Maxim-tile-200x200

Size is critical for hearables and wearables as they continue moving to smaller form factors. Most PMICs for these small, lithium-ion battery-operated devices require additional components, such as boost, buck, and low dropout (LDO) regulators; a charger; and current regulators for LED indicators. Designers of Bluetooth® headphones, activity monitors, smart garments, smartwatches, and other size-constrained […]

Maxim Integrated – MAX77650/MAX77651: Ultra-Low Power PMIC with 3-Output SIMO and Charger

FTMOct2017-MaximIntegrated-tile-200x200

The MAX77650 and MAX77651 feature single inductor multiple output (SIMO) buck-boost regulators that provide three independently programmable power rails from a single inductor, 150mA LDO, and three current sink drivers to reduce overall component count and maximize available board space. For desigexibility, the MAX77650 operates up to 3.3V and the  MAX77651 operates up to 5V—both include […]

Maxim Integrated – Choose a Flexible and Scalable Front-End Tuner for Your Software Defined Radio

FTMSept2017-MaximIntegrated-tile-200x200

Introduction Traditional radio receivers integrate a front-end tuner with a baseband processor, hardwired to one specific radio standard. This means that there are as many radio receiver chips as there are standards. In contrast, Software Defined Radio (SDR) architectures perform the baseband processing using software, enabling reception of a wide range of radio standards with […]

Maxim Integrated – Pack More Punch in Your Small Sensor While Keeping It Cool

Pg24_Maxim_thumb

Introduction Sensors have become ubiquitous in the industrial environment. As they increase in sophistication and shrink in size, sensors are enabling Industry 4.0. In turn, sensor electronics are becoming more complex, requiring on-board voltage regulators to deliver power more efficiently and with minimum heat generation. How do you safely deliver low-voltage power to tiny sensors […]
