The ISL26322FVZ-T from Intersil is a widening, low-power, charge-balancing, high-accuracy, 32-channel differential input, capacitive-to-voltage converter (CVC). It uses a single 3.3V supply and is designed to maximize performance while conserving power. The ISL26322FVZ-T is the best choice for any high-accuracy data acquisition applications, and it is ideal for industrial, medical, and aerospace applications.The ISL26322FVZ-T has an analog-input range of 0V to 3.3V that enables it to measure capacitive signals of ±32 pF. It can also measure differential inputs of ±10 V, giving it the capability to accurately measure and convert a wide range of signals. Additionally, its patented Smart Vout is capable of providing ±1.25 V output for ac signals and ±1.25 V to either side for dc signals, allowing for high-precision ac signal and dc data capture. The ISL26322FVZ-T boasts high accuracy of ±0.6% over its entire input range, as well as 14-bit resolution for improved system accuracy. The device is also capable of providing a fast conversion time of 1µs per channel, making it well-suited for fast data collection without sacrificing accuracy. Additionally, the low-power technology used in the ISL26322FVZ-T permits it to use less than 100 mW of power while actively operating, making it ideal for battery-powered systems.The working principle of the ISL26322FVZ-T is based on its low-power capacitive-to-voltage conversion architecture. Its 32 differential inputs sense and measure the charge created when a capacitive signal is applied. This charge is then converted to a voltage through a switched-capacitor architecture, which is then digitized to provide a digital output. This output is then transferred to a host processor, which can be used to further process the data.The ISL26322FVZ-T has a wide range of applications in the data acquisition, medical, industrial, and aerospace industries. It can be used for liquid level measurements, temperature sensing, flow rate measurement, pressure sensing, and position sensing. Additionally, it can be used for test and measurements systems, as well as to measure and monitor ac/dc current and voltage. In the medical field, the device’s accuracy and low power consumption make it ideal for monitoring vital signs such as heart rate, respiration rate, and blood pressure. Furthermore, its fast conversion time makes it well-suited for aerospace applications such as engine monitoring, navigation systems, and aircraft instrumentation. The ISL26322FVZ-T makes data acquisition applications much easier and more reliable by providing high accuracy, low power, and fast conversion times. Its wide range of applications make it suitable for many different fields, and its patented Smart Vout feature provides excellent ac/dc signal accuracy. Whether it is being used in a medical, industrial, or aerospace application, the ISL26322FVZ-T is sure to be a reliable and accurate solution.
