الوصف

نظرة عامة على المنتج

The MAX30003CWV+T is an ultra-low power, single-channel integrated biopotential analog front-end (AFE) from Analog Devices (formerly Maxim Integrated), designed for ECG (electrocardiogram) and R-to-R heart rate detection in wearable applications. It features 15.5-bit effective resolution with 5uVp-p noise, built-in R-R detection algorithm, and operates on just 85uW at 1.1V. The CWV package is a 30-bump wafer-level package (WLP) measuring 2.7 x 2.9mm.

مقدمة المنتج:MAX30003CWV+T مقدمة المنتج

The MAX30003CWV+T is an ultra-low power single-channel biopotential AFE from Analog Devices, designed for wearable ECG and heart rate monitoring. It achieves clinical-grade 15.5-bit effective resolution with just 5uVp-p input noise, while consuming only 85uW at 1.1V supply. The built-in R-R heart rate detector with configurable interrupts eliminates the need to run HR algorithms on the host MCU, significantly reducing system power. The 30-bump WLP package (2.7×2.9mm) is optimized for space-constrained wearable designs.

مبدأ العمل:MAX30003CWV+T مبدأ العمل

The MAX30003CWV+T operates as a fully integrated ECG analog front-end. The biopotential channel receives differential ECG signals at the ECGP and ECGN pins, which first pass through ESD protection and EMI filtering. The fast-settling input amplifier with high input impedance (>500MOhm) amplifies the microvolt-level ECG signal while rejecting common-mode interference (CMRR >100dB). A programmable gain amplifier (PGA) further conditions the signal before an anti-aliasing filter (AAF, -3dB at 600Hz). The signal then enters a high-resolution sigma-delta ADC with programmable decimation filter. The R-R detector algorithm runs on the digitized ECG waveform, identifying QRS complexes and outputting heart rate data via the INTB interrupt pin. The 32-word FIFO allows the host MCU to remain in deep sleep until enough data accumulates, reducing overall system power consumption. DC lead-off detection uses a 0.7uA current source to monitor electrode connectivity.
