資料

The ADS1293 incorporates all features commonly required in portable, low-power medical, sports, and fitness electrocardiogram (ECG) applications. With high levels of integration and exceptional performance, the ADS1293 enables the creation of scalable medical instrumentation systems at significantly reduced size, power, and overall cost.

The ADS1293 features three high-resolution channels capable of operating up to 25.6 ksps. Each channel can be independently programmed for a specific sample rate and bandwidth allowing users to optimize the configuration for performance and power. All input pins incorporate an EMI filter and can be routed to any channel through a flexible routing switch. Flexible routing also allows independent lead-off detection, right-leg drive, and Wilson/Goldberger reference terminal generation without the need to reconnect leads externally. A fourth channel allows external analog pace detection for applications that do not use digital pace detection.

The ADS1293 incorporates a self-diagnostics alarm system to detect when the system is out of the operating conditions range. Such events are reported to error flags. The overall status of the error flags is available as a signal on a dedicated ALARMB pin.

The device is packaged in a 5-mm × 5-mm × 0.8-mm, 28-pin LLP. Operating temperature ranges from –20°C to 85°C.
