Product Overview: ADS1293CISQ/NOPB

The ADS1293CISQ/NOPB is a high-performance, integrated analog front-end (AFE) device designed by Texas Instruments for biopotential and bioimpedance applications. This precision AFE is specifically tailored to meet the demanding needs of advanced medical instrumentation such as electrocardiograms (ECG), respiratory measurements, and fitness monitoring equipment.

Key Features

• Multi-Channel Flexibility: The ADS1293 features three low-noise programmable gain amplifiers (PGAs) and three high-resolution analog-to-digital converters (ADCs), providing simultaneous sampling of multiple channels.
• High Performance: With a data rate of up to 32k samples/second per channel, the device ensures accurate and high-speed data acquisition. Its 24-bit resolution ADCs offer precise signal quantization, making it ideal for capturing low-amplitude biopotential signals.
• Integrated Features: The device integrates several functions such as a right leg drive amplifier (RLD), a pace detection circuit, and a lead-off detection system, which simplifies design and reduces external component count.
• Low Power Consumption: Designed for battery-powered devices, the ADS1293 operates with a power-efficient architecture, minimizing power consumption for extended device operation.
• Compact Form Factor: Available in a compact QFN-32 package, the ADS1293CISQ/NOPB is designed for space-constrained applications, allowing for a reduced PCB footprint in end products.
