The ISL98002CRZ-170 Data Acquisition Analog Front End (AFE) is an entry-level AC performance AFE featuring two A/D channels, two GPI ports, and low power consumption. It is designed to provide high quality analog inputs, allowing the front-end to capture signals of varying size and complexity. The inherent flexibility and ease of integration make it suitable for a wide variety of applications from industrial, medical, and consumer markets.

The main features of the ISL98002CRZ-170 Data Acquisition Analog Front End (AFE) are its low power consumption and its dual A/D channels. It has a Channel A/D input range of ±1000mV, which makes it ideal for capturing small signals, such as those from temperature sensors. It also features an analog multiplexing capability, allowing selection of the most appropriate input channel for the task at hand. The input multiplexing is done via two GPI ports: the GPI0 port selects the input channel, and the GPI1 port selects the input polarity.

The ISL98002CRZ-170 Data Acquisition Analog Front End (AFE) also comes with a range of other features designed to improve its overall performance. It has a low noise floor of 82dBuV, meaning that it can capture accurate readings even in noisy environments. The die-level ESD protection ensures a reliable signal, and it also has a high-impedance input buffer to reduce interference from sources outside the device. It is also available with an external temperature sensor for temperature range compensation.

The ISL98002CRZ-170 Data Acquisition Analog Front End (AFE) can be used in various applications, including industrial automation, medical instrumentation, automotive, sound systems, and home entertainment systems. It is capable of measuring small signals from various types of sensor, and it is ideal for making sensitive analog measurements, such as temperature and vibration. With its low power consumption, the ISL98002CRZ-170 AFE is also suitable for battery-powered applications, such as portable medical devices and wearable sensors.

The ISL98002CRZ-170 Data Acquisition Analog Front End (AFE) uses two A/D channels to capture analog signals. The input signal is first amplified by the input buffer and then passed through a low-pass filter and a DC offset generator. From there, the signal is filtered and amplified by the variable-gain amplifier, and then sent to the A/D converter. After sampling the input signal, the A/D converter processes it and sends the resulting digital values to the output buffer. Finally, the output buffer feeds the digital data to the device’s output pins. This process is shown in the figure below.

In conclusion, the ISL98002CRZ-170 Data Acquisition Analog Front End (AFE) is a versatile AFE with two A/D channels and two GPI ports. It is designed to provide high-quality analog inputs, allowing the front-end to capture signals of varying size and complexity. Its low power consumption allows it to be used in a variety of applications, ranging from industrial, medical, and consumer markets. As such, it is an ideal choice for critical applications that require accurate analog input measurements.
