Analog Front-End (AFE) is a core component of a Data Acquisition system used to process and amplify analog signals for analog-to-digital conversion. AFE4490RHAR is a highly integrated analog front-end IC which is specifically designed for industrial and medical applications. It is an ideal choice for applications such as pH, respiratory monitoring, blood oxygen saturation, electrochemical, oxygraphic and hemodynamic analysis.

The AFE4490RHAR features low power duty cycle operation, providing ultra low power modes and high linearity performance. It also offers a wide range of integrated features, making it easy to implement AFE applications with a single device. It integrates four analog front-end subsystems: a dual-channel tracking ADC, differential amplifier, reference and amplifier.

The AFE4490RHAR operates with a single 3.3 V supply. It is capable of providing a wide range of gain settings, from 40dB to -50dB, to accommodate different input signal levels. It can also drive a wide range of loads, from 10 Ohms to 100 Ohms, allowing it to drive both high impedance and low impedance devices. Furthermore, it has selectable gain with automatic gain selection for optimal input signal levels for each channel.

The dual-channel ADC is responsible for converting the analog input signals into digital data for further processing. It can operate up to a maximum rate of 1 MS/s and has a maximum resolution of 14 bits. The ADC can be programmed to sample at any frequency from 0.1 Hz to 1 MHz. The differential amplifier helps to reduce the noise and distortion of the input signal by differential mode operation. It is also able to provide accurate and stable DC offset control. The reference and amplifier blocks are used to provide stable reference voltage and gain stability, respectively.

The AFE4490RHAR is optimized for low power operation, consuming only 1.8 mW when operating at a rate of 532 kHz. It is also capable of operating up to 20 MHz. The AFE is well-suited for portable and remote applications as it is packaged in an ultra-small 0.9 mm² size. Additionally, the AFE is fully certified, and carries the UL, CE, and FCC regulatory marks, making it compliant with various safety and EMC standards.

In summary, the AFE4490RHAR is an ideal solution for medical and industrial applications. It integrates an advanced range of analog front-end features, including a dual-channel tracking AGC, differential amplifier, reference and amplifier blocks, making it an effective choice for high-performance data acquisition systems. Furthermore, its low power operation and small package make it suitable for battery-operated and portable applications.
