Intersil HI7191IPZ

HI7191IPZ Overview
This particular component is manufactured by Intersil and falls under the category of Data Acquisition - Analog to Digital Converters (ADC). It is an ADC chip used for converting analog signals into digital data. The chip is designed to operate within a temperature range of -40°C to 85°C. One of the notable features of this chip is its Programmable Gain Amplifier (PGA), which allows for amplification of the input signal. The terminal finish of the chip is Matte Tin (Sn) - annealed, providing a protective coating. The base part number assigned to this chip is HI7191. The input type of this chip is differential, meaning it can process the difference between two input signals. It is classified as a Delta-Sigma ADC, which employs oversampling and noise shaping techniques to achieve high-resolution conversion. This chip requires an external reference voltage for accurate conversion. It utilizes the Serial Peripheral Interface (SPI) as its data interface, allowing for communication with other devices. The digital supply voltage required for this chip to operate is 5V. Additionally, it is compliant with the Restriction of Hazardous Substances Directive (RoHS), specifically ROHS3 Compliant, indicating that it meets the necessary environmental standards.
