The ISL98003CNZ-165 is a powerful analog front end (AFE) data acquisition IC used to sample low voltage analog signals and accurately digitize them. The device supports analog input ranges as low as -165 mV and features a low power, highly accurate data conversion technique called “true delta-sigma”. This technology enables the device to measure and digitally encode analog signals with very low intrinsic noise while at the same time greatly reducing power consumption.

The ISL98003CNZ-165 is well suited for analog signal conversion to digital values in sensor systems, medical instruments and data collection platforms. It includes a wide variety of analog input protection and signal conditioning features such as anti-aliasing filters, programmable voltage rails, and over-voltage protection. The device also supports dynamic range extension for applications requiring higher signal resolution. The on-chip real-time clock and temperature sensor make it an excellent choice for medical and environmental monitoring applications.

The ISL98003CNZ-165 operates on a 3V supply voltage and is able to achieve a sampling rate of 16k samples/s. The maximum resolution of the conversion is 16-bits, providing a very precise signal measurement. Additionally, the device features low latency and fast conversion time, which makes it suitable for real-time applications. The I2C interface allows software control of its on-chip features including digital filters and dynamic range extensions.

The ISL98003CNZ-165 works by using a delta-sigma modulator to convert an analog signal into a digital representation. The modulator utilizes a combination of an integrator and comparator to make an approximated digital representation of the input analog signal. As the integrated signal crosses a predetermined threshold, the comparator flips its output and the following samples constitute the digital representation of the signal.

In addition to its internal features, the ISL98003CNZ-165 also incorporates other features such as fault detection and alert functions, linearity correction and temperature compensation. Furthermore, the on-chip temperature sensor also allows the temperature of the device to be monitored in real time. All of these features are configurable in the I2C interface.

The ISL98003CNZ-165 is an ideal analog front end datasheet acquisition IC for low power, low voltage applications. It is highly integrative and includes a wide range of built-in protection and signal conditioning features. The low power and low intrinsic noise makes it suitable for medical and environmental monitoring, as well as sensor systems and data collection platforms. With its delta-sigma modulator, the device is able to accurately sample and convert analog input signals into digital representations, making it an ideal choice for a variety of applications.
