What are the key features of ADS1299-X?
- 24-bit resolution with 1 µVpp input-referred noise enables acquisition of microvolt-level EEG and ECG biopotential signals
- Up to 8 simultaneous differential input channels with integrated PGA eliminates external amplifier stages in biosignal front-ends
- Programmable data rates from 250 SPS to 16 kSPS accommodate both high-resolution low-bandwidth EEG and higher-bandwidth EMG applications
What is ADS1299-X used for?
ADS1299-X is purpose-built for medical and research biopotential acquisition instruments including EEG headsets, ECG monitors, and EMG measurement systems where 24-bit resolution and sub-microvolt noise performance are essential. Its multi-channel simultaneous sampling with integrated programmable gain amplifiers reduces system complexity and BOM cost in portable and wearable brain-computer interface devices. Research-grade EEG recording systems and clinical neurology workstations also employ this family for its low 1µVpp noise floor and high common-mode rejection.

Frequently Asked Questions
What resolution and noise performance does ADS1299-X provide for biopotential signal acquisition?
ADS1299-X delivers 24-bit resolution with an input-referred noise of approximately 1 µVpp at the lowest data rate of 250 SPS, enabling detection of sub-microvolt EEG alpha and theta signals. At higher data rates up to 16 kSPS, noise increases slightly but remains below 2 µVpp, suitable for surface EMG and ECG acquisition. This noise performance rivals discrete amplifier designs while reducing component count to a single-chip solution.
How many input channels does ADS1299-X support, and can they sample simultaneously?
The ADS1299-X family includes variants with 4, 6, or 8 differential input channels, all sampled simultaneously to preserve phase coherence between channels in multi-electrode EEG or ECG recordings. Simultaneous sampling eliminates the interchannel time skew introduced by multiplexed ADC architectures, which is critical for source localisation algorithms in 8-channel or 256-channel EEG arrays. Each channel includes an integrated programmable gain amplifier with gain settings of 1 to 24, covering the full dynamic range of biopotential signals from 1 mV ECG to 100 µV EEG.
Which medical and neuroscience applications are best matched to ADS1299-X?
ADS1299-X is optimised for EEG recording headsets, clinical ECG and Holter monitors, EMG prosthetic control systems, and brain-computer interface research platforms where 24-bit accuracy and 1µVpp noise are required. Its right-leg drive circuit output and high common-mode rejection of 110 dB minimum suppress 50Hz and 60Hz power-line interference in hospital and laboratory environments. Sleep study equipment and neurofeedback devices also use this family to capture slow cortical potentials below 1 Hz with minimal baseline drift.
What data rate range does ADS1299-X support, and how does it affect signal bandwidth?
ADS1299-X supports programmable output data rates from 250 SPS to 16 kSPS, corresponding to signal bandwidths of approximately 125 Hz at the lowest rate and 8 kHz at the highest rate. At 250 SPS, the 24-bit resolution and 1 µVpp noise provide the best dynamic range for DC-coupled EEG recordings. Switching to 16 kSPS extends bandwidth to capture higher-frequency EMG bursts or high-gamma EEG oscillations above 100 Hz, at the cost of slightly increased noise and higher SPI data throughput requirements to the host processor.
