ADS1196CPAG

Analog Front End (AFE) Overview

The ADS1196CPAG is a low-noise, 8-channel, 16-bit Analog Front End (AFE) designed for biopotential measurements. It integrates eight simultaneous sampling channels with Sigma-Delta converters, achieving a maximum sampling rate of 8 kS/s per channel. The device operates on an analog supply voltage ranging from 2.7 V to 5.25 V and a digital supply voltage between 1.65 V and 3.6 V. Key electrical specifications include a signal-to-noise ratio (SNR) of 97 dB and an integral nonlinearity (INL) of 15 ppm. Communication is handled via a standard Serial Peripheral Interface (SPI). The component is housed in a TQFP-64 package suitable for surface-mount installation.

Analog Front End (AFE) Feature Summary

• Eight simultaneous sampling channels with 16-bit resolution
• Low noise performance with 97 dB SNR
• Integrated internal and external reference options
• Supports differential and single-ended input types

Analog Front End (AFE) Applications

• Electrocardiogram (ECG) systems
• Electroencephalogram (EEG) monitoring
• Electromyography (EMG) acquisition

Analog Front End (AFE) Procurement Notes

Verify the specific suffix 'CPAG' against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with required analog and digital supply voltages during sourcing. Check for moisture sensitivity level requirements if storage conditions are not controlled.

Analog Front End (AFE) Selection Notes

Select this component when high channel count and simultaneous sampling are required for biopotential signals. Compare the 16-bit resolution and 8 kS/s speed against higher-resolution alternatives like the ADS129x series if lower noise or more channels are needed. Verify that the TQFP-64 footprint fits the target PCB layout constraints.

Analog Front End (AFE) Part Context

The ADS1196 belongs to the Texas Instruments ADS119x family of biopotential AFEs. It shares architectural similarities with the ADS1198 but offers a different channel configuration or feature set tailored for specific multi-channel medical instrumentation needs within the same product line.

Analog Front End (AFE) Replacement Considerations

The ADS1198CPAG is a closely related part within the same family. Verify functional differences such as channel count or integrated features before substitution. Other ADS119x variants may serve as alternatives depending on specific resolution or interface requirements.
