3 Channel AFE 24 Bit 28-WQFN (5x5) ADS1293CISQ/NOPB is a highly integrated, low-power 3-channel ECG Analog Front-End (AFE) from Texas Instruments. It is designed for portable and battery-powered medical devices, fitness monitors, heart-rate monitoring systems, Holter monitors, and other electrocardiogram (ECG) applications. The device integrates signal acquisition, filtering, lead-off detection, right-leg drive generation, and high-resolution analog-to-digital conversion into a single IC, reducing external component count and system cost. Key Features Three high-resolution ECG acquisition channels 24-bit analog-to-digital conversion Simultaneous pace detection support Ultra-low power consumption of approximately 0.3 mW per channel Low input-referred noise of 7 µVpp (40 Hz bandwidth) Programmable sample rates up to 25.6 ksps Differential input voltage range of ±400 mV Integrated EMI-hardened input filters Flexible input routing matrix Built-in Right-Leg Drive (RLD) amplifier AC and DC lead-off detection Integrated Wilson and Goldberger terminal generation Battery voltage monitoring capability Internal oscillator and voltage reference ALARMB pin for interrupt-driven diagnostics and fault reporting Multiple power-down and standby modes for battery-powered systems SPI-compatible digital interface Operating temperature range: –20°C to +85°C 28-pin WQFN package (5 mm × 5 mm) Typical Applications Portable 1-, 3-, 5-, 6-, 7-, 8-, and 12-lead ECG systems Holter monitors Event recorders Telemedicine devices Patient vital-sign monitoring equipment Automated External Defibrillators (AEDs) Sports and fitness heart-rate monitors Wearable medical devices Hashtags #commonpartslibrary #integratedcircuit #TexasInstruments #ADS1293 #AFE #AnalogFrontEnd #ECG #Electrocardiogram #MedicalElectronics #HealthTech #WearableDevices #HeartRateMonitor #PatientMonitoring #BiomedicalEngineering #24BitADC #LowPowerDesign #SPI #SignalConditioning #PortableMedicalDevices #HolterMonitor #Telemedicine #VitalSignsMonitoring #EmbeddedSystems #MixedSignalIC #WQFN28 #BatteryPoweredDevices #MedicalInstrumentation
