Data Acquisition – Analog Front End (AFE) is a system used to measure and convert physical signals such as sound, temperature, and velocity into digital signals so that the signals can be processed by a computer. To carry out this process, an analog front-end (AFE) is used, which typically consists of amplifiers, filters, and/or analog-to-digital converters (ADCs). The ADS1293CISQE/NOPB is an example of an AFE, which is a single-channel, four-channel, or eight-channel AFE. This AFE can convert analog signals into digital signals, filter them, and amplify them.

The ADS 1293CISQE/NOPB is a low-noise, low-power, differential input AFE that can convert up to four differential analog inputs into digital data. It has a flat frequency response, making it ideal for use in biomedical applications such as electroencephalography (EEG), electrocardiography (ECG), galvanic skin response (GSR), and electromyography (EMG). It also has excellent signal-to-noise ratio (SNR) and low total harmonic distortion (THD), making it suitable for use in audio recording or other applications that require a clean and precise signal.

The ADS 1293CISQE/NOPB AFE integrates filters, amplifiers, and a 16-bit Analog-to-Digital Converter (ADC) into one device. It has the ability to accept up to four differential inputs, amplify them if needed, and filter out noise before being digitized. The AFE alsohas a “speedy” mode, which can sample at a rate of up to 1000 kSps.

The ADS 1293CISQE/NOPB also features a dynamic “noise-reject” mode, which can reject large-scale noise like power line interference. This dynamic noise reject mode automatically adjusts the gain of the amplifier to minimize the peak-to-peak noise. The AFE also has an automatic shut-off feature, which will turn off the device if it detects sustained periods of high noise levels.

The ADS 1293CISQE/NOPB also includes multiple diagnostic features, such as an overload-protection circuit, an underrange alert, and a “clip detection” feature. This AFE also integrates calibration and external reconfiguration capabilities.

In summary, the ADS 1293CISQE/NOPB is an analog front-end (AFE) system used to convert analog signals into digital data. It has the ability to process up to four differential inputs and features a dynamic noise-rejection mode to reduce power line interference. The AFE also includes diagnostic features, calibration, and external reconfiguration capabilities to make it a versatile AFE for biomedical and other applications.
