ADS7947SRTER Overview


The analogue to digital converter is designed with 12 Bits.The AD converter is embedded in the 16-WFQFN Exposed Pad package.The ADC converter is packaged in the way of Tape & Reel (TR).The ADC converter is equipped with 1 Functions .There are 16 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 3.3V.The A/D converter has 2 channels.The is equipped with 16 pin count.The peak reflow temperature (Cel) amounts to 260 to be essentially indestructible.There are ADC, SUCCESSIVE APPROXIMATION converters based on the source input voltage and the output voltage.This electronic AD converter is mounted in the way of Surface Mount.When operating, analogue to digital converter's operating temperature should be kept at -40°C~125°C.The number of samples of audio recorded every second is 2M Hz.The input type of this electronic AD converter is Pseudo-Differential.There are External reference types differentiated on the way by which they are garbage collected. This electronic digital converter is configured in such a way that MUX-S/H-ADC.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.The architecture that analogue to digital converter's core adopts is SAR.There are 16 pins, which are pronged contacts as part of a signal interface in a computer or other communications device. The supply/analog voltage of this electrical ADC converter is 2.7V~5.25V, which converts alternative voltage (AC voltage) to regulated direct voltage (DC voltage) and provide regulated DC power in order to drive a load.The number of pixels of this electrical AD converter is 1.5 B, which is on a display or in a camera sensor (specifically in a digital image).It belongs to ADS7947 family.This electrical digital converter is lead free, which means made without lead, or has no lead added to it.It is possible to categorize the supply type according to Single.The supply/digital voltage of this electrical AD converter is 1.65V~5.25V.The ADC converter operates with the maximal supply voltage of 5.5V.It operates with the minimal supply voltage of 2.7V.The output formats of this electrical AD converter are SERIAL , which are used to determine which data is exported and how data is displayed in many areas of OLIB.This electrical digital converter operates from a supply voltage of 3.3V.As an undesirable derivative of its primary action, The heat (energy loss or waste) that this electronic or electrical digital converter produces is 7.5mW.The number of channels is growing strong/weak: 2.There are 1 A/D converters, which are used to convert an analog signal like voltage to digital form so that it can be read and processed by a microcontroller. The digital converter operates with the minimal supply voltage (DC) of 1.65V.The ADC converter operates with the maximal supply voltage (DC) of 5.5V.
