AFE4950

適用于可穿戴設(shè)備、光學心率監(jiān)測和 SpO2 的超小型集成式 AFE

AFE4950 器件是一款用于同步采集 PPG 和 ECG 信號的模擬前端 (AFE)。該器件還可用于心率監(jiān)測 (HRM) 和外周毛細血管氧飽和度 (SpO2) 測量等光學生物傳感應用。ECG 信號鏈支持雙電極和三電極配置，并具有集成式右腿驅(qū)動 (RLD) 緩沖器。ECG 信號鏈還可用于以較低功耗連續(xù)監(jiān)測一對電極間的阻抗。; ? 支持同時且同步采集多達 24 個 PPG 和單引線 ECG 信號。\n? 在每個相位內(nèi)均可實現(xiàn)靈活的 8 個 LED、4 個 PD 分配\n? ECG 信號鏈： \n? 頻率高達 2kHz 的單引線 ECG 信號采集\n? 用于驅(qū)動第三電極的 RLD 輸出\n? 輸入噪聲：0.7μVrms\n? 支持高達 ±0.65V 的差分直流失調(diào)電壓和 +/-0.55V 的共模范圍\n? 可編程 INA 增益：11、21\n? 可實現(xiàn)快速飽和恢復的高通濾波器\n? 集成式 300Hz 抗混疊低通濾波器\n? 交流、直流導聯(lián)脫落檢測：2.9nA 至 92.5nA\n? 低功耗持續(xù)導聯(lián)接通檢測\n \n;
