## ADC sampling and signal reconstruction

Hello I have any question about signal sampling theory. I have signal generated from DDS (10bit with good reconstruction filter) , signal is sinus of known frequency 100 kHz. I need to know as precisely as possible amplitude and time zero crossing I have 12bit adc with 5 MSPS (STM32F303). i.e. 50 samples per period or 1 sample/7,2 degree. Th

## Error while connecting analog to digital block in 12bit ADC layout

Pls help, I am doing the layout of a 12bit adc. while connecting between the digital(3.3LvTr, connected to VDD 1.2V)and analog section(3.3lvTr, connected to AVD 3.3v), all the rules for 3.3v analog section transistors are flashing for the 1.2v digital connection. I have added an antenna diode to the analog gate which is connected to the digit

## Performance Analysis Of A Designed ADC

I've designed a pipeline adc (12-bit). How to take performance analysis such DNL, INL and SFDR analysis (using MATLAB commonly or any other)?

## Mcp1541 4.096v reference ic

I want a stable reference voltage source for 12bit adc conversion . For that purpose i opted for mcp1541 from microchip .But there is difference in the o/p for every part . 1st IC :4.098V Dc. 2nd Ic : 4.110V DC. 3rd Ic : 4.084 V DC. Can somebody explain why this kind of response is there . Is there some ic with only +-1mV variation in voltage re

## 12 bits adc pic microcontroller

You better explain more detaily what exactly do you developing and what for. Because at this moment it looks like something impossible. Even with 24 bit adc 1mV with DC motor sounds... not relible.

## Very strange results when plotting a digitized sinewave, using a ?C's 12bit ADC.

Hello. I am using a arduino Due(SAM3X8E) with its 12bit adc to read a sine wave, the reference voltage is 3V and the sine wave swings approximatly between 0 and 3V. I have writen a program to use DMA(Direct Memory Access) on the SAM3X8E ?C to store the adc results and then I send them over serial to matlab and plot the results. But I (...)

Hi All, Has anybody come across a multichannel adc which can sample its analog inputs simultaneously ? Most of the multichannel adcs that I have come across have some sort of multiplexor or S/H circuit, so not simultaneous in real sense but will work for frequencies lower than 1MHz or so. BR,

## 12Bit Pipeline ADC is not working in PIC24FJ128GC006

I am uisng 12bit Pipeline adc in PIC24FJ128GC006, MPLAB V8.8 IDE, C30 compiler. by using sample code from PIC24F family datasheet i am not able get output, and also from silicon errata of this family some errors regarding sampling,calibration for this work around process also done and still i am not able to get the output ... am i mi

## Bipolar ADCs which can give digital output with precision of decimal point

Hello, Please suggest me some IC names of Bipolar adcs that gives digital output with precision of 2 to 3 decimal points. Example:If input is 6.125 adc output should be "00000110.001" Please reply me as soon as possible. Thank you.

105428 Microcontroller: MSP430 ( ) I'M NEW TO MICROCONTROLLER AND STUCK ON THIS PROBLEM FOR AWHILE. Along the way, i know how to bit masking using OR/AND operation. But i have no idea how to convert 12 bit adc to 9 bit adc through masking ( as the questions asked) and how masking h

## Front-End Amplifier for multiple SAR ADC?

One amplifier is likely better, otherwise any gain/offset mismatch between the multiple amplifiers will cause artifacts in the sampled data. You should spec the amp as if you were really driving a single adc operating at 10msps.

## Binary bit detection from 70MHz IF input

Hello, I am trying to recover transmitted binary bit stream from digital receiver 70MHz if input. I am using 12bit adc @ 140MHz sampling rate. The transmitted data rate is 512kbps. How to decide the binary bit data at adc output?

Greetings, I want to set two port pins for analog inputs for a 12bit adc in dsPIC30F4013. i know that i have to use the TRIS and ADPCFG registers to do that. I'm not familiar with C language. in assembly i know how to set it. help would be appreciated.

## Reg: PMOD AD1 usage for a FPGA base app

Hi, I am making use of the PMOD AD1 (AD7476-12bit) for my application. I have used a FSM to interface the PMOD to the FPGA. From the timing diagram from the data sheets available, the adc's poweron is dependent on the nCS signal. And I have a doubt that what would happen to the data converted (SDATA), if the nCS pin is pulled up even before

Hi guys, I have a few questions. To design a very fast pipeline adc like this, which topology do you recommend for the MDAC OTA ? Can you give me reasonable specs to start from ? Also if you have any pdf with a similar design, it would be great to attach it here. Thanks

## interfacing 12bit ADC in SPI mode?

hello you have to use an integer ( 16 bits = 2 bytes !) variable to store the result. see example in mikroC it's not the same device , but the approach is similar.. test on MCP3304 4x 13bits adc value on 12 bits unsigned in single end mode. ex: 0 ? 5V for 0 ..4095 value if your reference is 4.09

## How to achieve a very low power in design the 12bit 100MHz ADC

I have seen a datasheet of 12b 100M adc designed by IQ-analog. It only comsume 20mw power in 100MHz. Can anyone give me some information about how to realize the performance?Can anyone give me some materials?Thank you very much. the datasheet is in the following,

Hello, I need source code for 12bit adc(TLV2543) to interface with picdem2plus board using c to display adc value on 16*2 lcd display. Can u help me with codes at the earliest... Regards, kavya

## ADC Function Linear or what?

I am using PIC18F4523 to measure 0-5V using adc. For 0V I'm getting a value of 0 and for 5V I'm getting 4095. I want to know wheather the adc function is linear or logarithmic, or wheather it is linear to some value and then logarithmic.
