AD7641AST Product Details

AD7641AST Overview


The analogue to digital converter is designed with 18 Bits.The AD converter is embedded in the LQFP package.The ADC converter is equipped with 1 Functions .There are 48 terminations in this electrical AD converter, which are the practice of ending a transmission line with a device that matches the characteristic impedance of the line.The analogue to digital converter is powered from a supply voltage of 2.5V.The A/D converter has 1 channels.The is equipped with 48 pin count.The peak reflow temperature (Cel) amounts to 220 to be essentially indestructible.There are ADC, SUCCESSIVE APPROXIMATION converters based on the source input voltage and the output voltage.The Sample/Track and Hold component of this electronic AD converter provides a way to sample a continuously varying analog signal and to hold or freeze its value for SAMPLE time.There are 48 pins, which are pronged contacts as part of a signal interface in a computer or other communications device. The number of pixels of this electrical AD converter is 2.25 B, which is on a display or in a camera sensor (specifically in a digital image).This analogue to digital converter is included in Analog to Digital Converters.The output formats of this electrical AD converter are PARALLEL, WORD , which are used to determine which data is exported and how data is displayed in many areas of OLIB.The maximal analog input voltage of this electrical AD converter is 2.5V.The ADC converter operates from 2.52.5/3.3V power supplies.The minimal analog input voltage of this electrical AD converter is -2.5V.There are 1 analog transmissions, which are both based on how they adapt data to combine an input signal with a carrier signal. The operating temperature should not exceed 85°C.The minimal operating temperature should exceed -40°C.
