ADS1299-6PAG

Analog Front End (AFE) Overview

The ADS1299-6PAG is a low-noise, analog-to-digital converter (ADC) featuring six channels. It utilizes a sigma-delta architecture with a 24-bit resolution and supports sampling rates up to 16 ks/s. The device accepts differential or single-ended inputs via an SPI interface. It operates on a 5 V analog supply and a 1.8 V digital supply, achieving a signal-to-noise ratio of 121 dB. Packaged in a TQFP-64 surface-mount format, it integrates programmable gain amplifiers for biomedical signal acquisition.

Analog Front End (AFE) Feature Summary

• Six-channel simultaneous sampling capability
• 24-bit resolution with 121 dB SNR
• Integrated PGA and internal reference
• SPI digital interface

Analog Front End (AFE) Applications

• Electrocardiography (ECG)
• Electroencephalography (EEG)
• Biomedical impedance measurement systems

Analog Front End (AFE) Procurement Notes

Verify the specific suffix '6PAG' against the manufacturer's official datasheet to confirm the channel count and package type. Ensure compatibility with required voltage levels and SPI timing parameters before integration into the design.

Analog Front End (AFE) Selection Notes

Select this component when six synchronized channels are required for high-fidelity bio-potential recording. Confirm that the 1.8 V digital logic level matches the host microcontroller interface and that the TQFP-64 footprint fits the PCB layout constraints.

Analog Front End (AFE) Part Context

This part belongs to the ADS1299 family of integrated analog front ends designed for biopotential measurements. The '-6PAG' designation specifies the six-channel variant within the broader eight-channel capable series, packaged in a TQFP-64 housing.

Analog Front End (AFE) Replacement Considerations

The ADS1299IPAG serves as a verified substitute offering eight channels instead of six. Verify pinout compatibility and software register adjustments when migrating from the six-channel to the eight-channel variant.
