ADS1299-6PAGR

Analog Front End (AFE) Overview

The ADS1299-6PAGR is a low-noise, multichannel analog-to-digital converter (ADC) featuring six simultaneous-sampling channels. It utilizes a 24-bit delta-sigma architecture with integrated programmable gain amplifiers (PGA), internal reference, and oscillator. The device supports data rates from 250 SPS to 16 kSPS and operates on single or dual power supplies. Key electrical specifications include an input-referred noise of 1.0 μVPP at 70-Hz bandwidth and a common-mode rejection ratio (CMRR) of -110 dB. It communicates via SPI interface in a TQFP-64 package.

Analog Front End (AFE) Feature Summary

• Six-channel simultaneous sampling with 24-bit resolution
• Integrated PGA with gains of 1, 2, 4, 6, 8, 12, or 24
• Low input-referred noise: 1.0 μVPP (70-Hz BW)
• Onboard oscillator and internal voltage reference

Analog Front End (AFE) Applications

• Electroencephalogram (EEG) systems
• Electrocardiogram (ECG) monitoring
• Auditory evoked potential (EAP) measurement
• Brain-computer interface (BCI) devices

Analog Front End (AFE) Procurement Notes

Verify the suffix 'R' indicates tape-and-reel packaging for automated assembly. Confirm the specific revision level matches design requirements. Ensure ESD handling protocols are followed during storage and installation. Check RoHS compliance status against current regulatory standards.

Analog Front End (AFE) Selection Notes

Select this model for applications requiring exactly six synchronized bio-potential channels. Compare against the ADS1299IPAG if eight channels are needed. Verify that the 16 kSPS maximum sampling rate meets signal bandwidth requirements. Ensure system power budget accommodates approximately 5 mW per active channel.

Analog Front End (AFE) Part Context

This component belongs to the Texas Instruments ADS1299 family of biopotential ADCs. It serves as a specialized analog front-end for medical instrumentation. The part integrates signal conditioning and conversion functions typically requiring multiple discrete components.

Analog Front End (AFE) Replacement Considerations

The ADS1299IPAG offers identical functionality but provides eight channels instead of six. Verify pin compatibility when substituting between different channel counts within the same series.
