ADS1293 Digital Electrocardiogram (ECG) Module Physiological Signal Measurement 3-Channel 24-Bit Analog Front End

Product Features:
The ADS1293 includes all the features typically required in portable, low-power medical, sports, and fitness electrocardiogram (ECG) applications. It provides three high-resolution digital ECG channels with synchronized pace outputs. Each channel can be configured for a specific sampling rate and bandwidth, allowing users to optimize the configuration for performance and power consumption. All input pins include an electromagnetic interference (EMI) filter, and input channels can be selected via a flexible routing switch. It also features AC and DC lead-off detection, right leg drive and Wilson/Goldberger reference termination generation without external lead reconnection, an ALARMB pin for interrupt-driven diagnostics, battery voltage monitoring, a built-in oscillator and reference, and flexible power-down and standby modes.
