MAX8614BATD/V+T

Overview

The MAX8614BATD/V+T is a complete single-channel optical data acquisition system designed for pulse oximetry and heart-rate monitoring. It integrates three programmable high-current LED drivers capable of driving up to six LEDs, with dual-device master-slave configurations supporting up to twelve LEDs. The device features a low-noise analog front end (AFE), a 19-bit charge-integration ADC, and an industry-leading ambient light cancellation circuit. Packaged in a compact WLP format, it supports wearable health applications requiring low power consumption and high dynamic range.

Feature Summary

• Integrates three programmable high-current LED drivers for multi-LED configurations
• Includes a low-noise signal conditioning analog front end with a 19-bit ADC
• Features advanced ambient light cancellation for superior environmental suppression

Applications

• Wearable pulse oximeters
• Heart-rate monitors
• Fitness and health tracking devices

Procurement Notes

Verify the specific suffix 'V+' against the manufacturer's official documentation to confirm compliance status and package variant. Confirm availability through authorized distributors as supply may be restricted. Ensure the component matches the required thermal and electrical specifications for the target application before integration.

Selection Notes

Select this component for designs requiring integrated optical sensing with minimal external components. Consider the master-slave capability if higher LED counts are needed. Evaluate the WLP package size constraints against the PCB layout requirements. Verify that the operating temperature range meets the environmental conditions of the intended deployment.
