The ADAS1000-4BSTZ-RL Analog Front End (AFE) is designed for electrocardiogram (EKG) applications. The device offers a low noise 4-channel simultaneous acquisition system featuring a 30-bit ADC, sample rates up to 800 kHz, and high accuracy. The ADAS1000-4BSTZ RL features a low power, wide bandwidth analog-to-digital conversion system that allows for wide dynamic range and low distortion. The design helps minimize the noise and crosstalk between the four channels by using wideband amplifiers and a quad-channel switch matrix. The ADAS1000-4BSTZ-RL is an integrated circuit (IC) capable of transforming input signals from the electrodes into digital signals that are processed and accurately analyzed by the system. This IC combines the low-noise amplifier, an ADC, amplifier, and a switch network, together into a single integrated circuit. The low-noise amplifier performs two functions. First, it amplifies the raw signals captured by the electrodes, providing an adjustable gain ranging from 0.5 to 5.0 Voltage peak-to-peak (Vpp). The amplifier also spectrally whitens the signal, which improves the signal-to-noise ratio and removes the low-frequency background noise. The ADC then converts the amplified signal into a digital signal, typically with a range of 8- to 24-bit resolution. The ADC provides a low-noise and high accuracy conversion, and the sampling rate of 800 kHz gives the unit a wide bandwidth. The final component of the ADAS1000-4BSTZ-RL is the digital signal processor (DSP). The DSP processes and analyses the converted signal, allowing for the evaluation of signal features such as heart rate, T-Wave or P-Wave, QRS & ST intervals, and R-wave amplitude. The algorithm is adjustable, and the system can also be configured to monitor post-T Wave depression or signal amplitude stability. The ADAS1000-4BSTZ-RL is easy to use and can be controlled through an I²C or SPI interface. The device also includes a full-featured software library that supports the program configuration and development process. This includes various modules such as signal filtering, signal processing, feature detection, heart rate calculation, and much more. Overall, the ADAS1000-4BSTZ-RL is an effective, accurate, and easy-to-use data acquisition system for EKG applications. It features a low-noise amplifier, a wide range of adjustable gain, an accurate ADC, and a comprehensive DSP for signal analysis. The design helps reduce noise and crosstalk and allows for easy configuration and a wide range of features that can be used for monitoring diagnostics.
