ADS1293CISQE/NOPB - TI Function Overview

The ADS1293CISQE/NOPB is a 24-bit 3-channel low-power Analogue Front End for bio potential measurements. The ADS1293 enables the creation of scalable medical instrumentation systems at significantly reduced size and power. The analogue front end features 3 high-resolution channels capable of operating up to 25.6kSPS. 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 need to reconnect leads externally. A fourth channel allows external analogue pace detection for applications that do not use digital pace detection. This device incorporates a self-diagnostics alarm system to detect when the system is out of the operating conditions range.
