TIADS1298
Overview
The ADS1298 is a highly integrated 24-bit analog front-end (AFE) specifically designed for medical imaging and biopotential measurements. It combines eight simultaneous-sampling channels with a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator to simplify the design of multi-lead ECG and EEG systems.
Why Choose This Part
It significantly reduces power consumption to as low as 8.8mW at 3V while integrating critical medical functions like respiration impedance and pace detection. The simultaneous-sampling architecture eliminates the phase delays found in multiplexed solutions, ensuring high signal integrity for diagnostic-grade equipment.
Applications
Key Specifications
Getting Started
Designers should utilize the ADS1298ECGFE-PDK performance demonstration kit, which includes the evaluation board and XMOS-based motherboard. Firmware development typically involves interfacing via SPI and managing the DRDY interrupt for data retrieval, while leveraging the internal test signals for initial calibration.
