TI has low noise chip for monitoring brain waves
Texas Instruments has introduced a very low noise electroencephalography (EEG) analogue front end AFE device.
It is used for non-invasive monitoring of brain waves. The 24-bit, 8-channel ADS1299 is the first simultaneously sampling EEG AFE with input-referred-noise as low as 1µVpp.
The ADS1299 was designed for manufacturers of extra-cranial biopotential measurement equipment who want to reduce board space, design time and cost while improving performance.
It can be used in EEG equipment to monitor bispectral index, evoked potentials and event-related potentials to diagnose brain injuries, strokes and sleep disorders.
The ADS1299 can also be used in ultra-high-performance medical diagnostic and research-grade electrocardiogram (ECG) equipment.
The ADS1299 Performance Demonstration Kit (ADS1299EEG-FE) includes easy-to-use evaluation software; built-in analysis tools, including oscilloscope, FFT and histogram displays; flexible input configurations; optional external reference circuits; and the ability to export data in simple test files for post processing. An IBIS model to verify board signal integrity requirements is also available.
The ADS1299 is available in a 10-mm by 10-mm QFP package.
