概述

Description

MAX30102EFD+ is a compact optical biosensor module from Maxim Integrated for wearable heart-rate and SpO₂ sensing. It combines red and infrared LEDs, a photodiode, and a high-performance analog front-end with A/D conversion, enabling reflectance PPG measurements from tissue. Interfaces are I2C, with programmable LED drive currents and sample rates, and it supports ambient-light rejection and FIFO/data registers for efficient data streaming.
Key points:
- Dual LED (red and IR) with configurable drive current
- Integrated photodetector and AFE with ADC
- I2C interface, programmable sample rate, ambient-light cancellation
- Low power, small footprint; typically 1.8–3.3 V supply
- Designed for wearables and portable medical/fitness devices
Usage: connect to a microcontroller, configure LEDs and sampling, read data, and apply HR/SpO₂ processing in software. Note: consult the latest datasheet for exact specs and safe operating procedures; not a standalone medical device.

Features

Here are the core features of MAX30102EFD+ (compact, wearable pulse oximeter/heart-rate sensor):
- Dual-wavelength LED drivers and photodiode: Red and IR LEDs with programmable drive currents.
- On‑chip optics and sensing: ambient-light cancellation and high-dynamic-range photodetector.
- Analog front-end and ADC: 16‑bit ADC with built-in DSP for PPG signals.
- Data interface: I2C with configurable address; data-ready/interrupt outputs.
- FIFO and registers: programmable sample rate and onboard FIFO for multiple samples; HR/SpO2 results exposed via registers.
- Heart rate and SpO2 ready to read: optimized for wearable wellness and fitness applications.
- Power management: low-power modes with wake/sleep/shutdown options.
- Package: very small 8-pin EFD+ package suitable for compact wearables.
- Operating range: designed for battery-powered wearables (typical temperature range specified in datasheet).
Note: For exact voltage, timing, and register details, refer to the official MAX30102EFD+ datasheet.

Package

The "EFD" suffix denotes Maxim's EFD package — a wafer-level land-grid-array (LGA/WLP) optical-sensor package. For exact pin count, footprint and mechanical dimensions, see the MAX30102 datasheet.

Pinout

The MAX30102EFD+ comes in a 10-pin LGA package. Its pins provide:
- VCC (power supply)
- GND (ground)
- SDA (I²C data)
- SCL (I²C clock)
- INT (interrupt / data-ready)
- LED driver pins for the red and IR LEDs (LED anode/cathode pairs)
- Photodiode input(s)/analog front-end connections for the sensor detector
- One or more NC (no-connect) / substrate pins
Note: Exact pin numbers, pin names, electrical characteristics, and package outline should be confirmed from the MAX30102 datasheet for wiring and layout.

Manufacturer

The MAX30102EFD+ is a product of Maxim Integrated (now part of Analog Devices, Inc.). Analog Devices is an American multinational semiconductor company that designs and supplies analog, mixed‑signal, and sensor integrated circuits (including optical heart‑rate and pulse‑oximetry sensor modules).

Application

Key application areas:
- Wearables: smartwatches, fitness bands, armbands for continuous HR and SpO2 (PPG)
- Health-monitoring devices: fingertip pulse oximeters, remote patient monitoring/telehealth
- Sleep and activity tracking: HR, SpO2, motion-assisted analysis
- Medical-grade and consumer devices in clinics and home care
- DIY/prototyping: education and hobbyist sensors for PPG/SpO2

Equivalent

There’s no perfect drop‑in clone of the MAX30102EFD+. Closest direct alternatives in the same family: MAX30101, MAX30105 (Maxim/Analog Devices) and the older MAX30100. Functional equivalents from other vendors: TI’s AFE4490/AFE4403 (optical AFEs that need external LEDs/PDs), Silicon Labs Si114x series. Choose by interface, LED/PD integration, package and firmware/algorithm support.
