Key Features

  • 4-channel, 24-bit delta-sigma ADC with <1 µVPP input-referred noise for high-precision biopotential acquisition
  • Integrated programmable gain amplifier (PGA) with gains of 1, 2, 4, 6, 8, 12, and 24 for flexible signal conditioning
  • On-chip bias drive, lead-off detection, and SPI interface reduce external component count in medical designs
  • Supports ±4.5V analog input range and operates from a 2.7V to 3.6V supply for low-power portable systems
  • 64-pin TQFP package (PAGR) simplifies PCB layout in space-constrained wearable and clinical devices

Applications

The ADS1299-4PAGR is purpose-built for medical-grade biopotential measurement systems, including electroencephalography (EEG), electrocardiography (ECG/EKG), electromyography (EMG), and other biosignal monitoring equipment. Its ultra-low noise floor and integrated analog front-end make it ideal for portable patient-monitoring devices, neuroscience research instruments, and clinical diagnostic systems. The device is also well-suited for industrial bio-impedance sensing and high-precision multi-channel data-acquisition applications where signal integrity is critical.

Frequently Asked Questions

What is the resolution and noise performance of the ADS1299-4PAGR?

The ADS1299-4PAGR provides 24-bit resolution with an input-referred noise as low as 1 µVPP at a data rate of 250 SPS and a PGA gain of 24. This ultra-low noise level makes it well-suited for capturing small biopotential signals such as EEG (typically 1–100 µV) without requiring additional external amplification stages.

What applications is the ADS1299-4PAGR designed for?

The ADS1299-4PAGR is specifically designed for biopotential measurement applications including EEG, ECG, EMG, and other medical biosignal acquisition systems. Its integrated PGA, bias drive amplifier, and lead-off detection circuitry reduce the number of external components needed, making it ideal for wearable health monitors, clinical diagnostic equipment, and neuroscience research instruments.

What package and interface does the ADS1299-4PAGR use?

The ADS1299-4PAGR is housed in a 64-pin TQFP (PQFP-G64) package with a 10×10 mm body, which balances compact PCB footprint with accessible pad pitch. It communicates via a standard 4-wire SPI interface supporting up to 10 MHz SCLK, enabling easy integration with common microcontrollers and DSPs in both portable and bench-top designs.

Can the ADS1299-4PAGR be used in daisy-chain configurations for more than 4 channels?

Yes. Texas Instruments provides a daisy-chain feature that allows multiple ADS1299-4PAGR devices to be cascaded on a single SPI bus, effectively expanding the system channel count in multiples of 4. This is commonly used in high-density EEG systems that require 16, 32, or more simultaneous recording channels while minimizing digital I/O requirements on the host processor.
