Analog Devices / Maxim Integrated MAX30003 생체전위 AFE
Maxim Integrated MAX30003 Biopotential 아날로그 프론트 엔드 (AFE)는 임상용 ECG AFE로서 고해상도 데이터 컨버터를 포함하고 있습니다. MAX30003은 웨어러블 응용기기를 위한 완전, 생체전위, 아날로그 프론트 엔드 솔루션을 제공합니다. 장치는 임상 및 피트니스 애플리케이션에 높은 성능을 제공합니다. MAX30003은 긴 배터리 수명을 위한 초저전력의 단일 생체전위 채널입니다.
The MAX30003 has ESD protection, EMI filtering, internal lead biasing, DC leads-off detection, ultra-low power leads-on detection during standby mode, and extensive calibration voltages for built-in self-test. Soft power-up sequencing ensures no large transients are injected into the electrodes. The MAX30003 also has high input impedance, low noise, high CMRR, programmable gain, various low-pass and high-pass filter options, and a high-resolution analog-to-digital converter. The device is DC coupled, can handle large electrode voltage offsets, and has a fast recovery mode to quickly recover from overdrive conditions, such as defibrillation and electrosurgery.
The Analog Devices MAX30003 Biopotential AFE is available in a 28-pin TQFN and 30-bump Wafer-Level Package (WLP), operating over the 0°C to +70°C commercial temperature range.
