hi, 1-why ADC op-amp use -5v 0v +5v supply power why not use single supply?? 2-the -5v 0v +5v connected to low voltage 3v ADC that's mean more op-amp gain can damage the high cost ADC ?
Hi All, What is the preferred easiest way to drop 3.3v usart pins to 1.8v to interface to an external device. I cannot change the Micro Vin voltage, so I will have to lower the voltage level external. Is it acceptable to use two resistors and create a potential divider, or would you recommend another method. I have already built the board
Unless the 3.3V FPGA has 5V tolerant inputs (only a few FPGAs have this feature) the 5V will exceed the maximum input voltage of the 3.3V FPGA and the 3.3V FPGA input connected to the 5V FPGA will be damaged. The solution is a) don't do this use the same voltage for the I/O that interface between FPGAs (3.3V). Most FPGAs allow for different bank v
hi ! i want to send text msgs from my AVRmega micro, how easy or difficult it is to interface this module to my micro ? does this module has all hardware built in and just needs to be programmed? does all local carrier SIM works on it like T-mobile, AT&T , Verizon etc ? any guidance is highly apprciated. thanks
Please let me know that I want to interface CT of 30/5A and 60/5A with arduino but issue is that how arduino recognize which is CT connected 30/5A or 60/5A?
Hi, I am trying to interface Microcontroller operating with 3 Volts and Modem operating with 4.2 Volts using UART (Rx and Tx) lines. Can I interface them directly or do we need to use any circuit inbetween. Could you please suggest me any circuit to interface. Thanking You, Ravi Kumar G
Hello All, I want to interface between MMC card and USB pen drive with a PIC 16F controller. My problem is voltage level two devices, USB has 5V logic and SD card operates on 3.3V, So how can I do this with out voltage level convertors or anything else am I missing? I am New to USB, So please give me if you have any sample code for USB interfacin
Hi, My pir sensor output is showin only 3.3 V , & i would like to interface this to PORT B of pic16f877a but then inorder to make the port high , there should be 5V , ryt? & but PIR Sensor Output is only 3.3V , So how i can solve this. Should i use relay or something ? or is there any other way like using the internal pull up resistors of p
Hello, Using LPC2148 I want to run a DC Motor using relay and ULN2003. I was able to do comfortably with 8051 but got stuck with LPC2148. Please find the Image. The same connections in the figure with 8051 was working fine. Please help in switching the relay using LPC2148
I am trying to interface MQ7 (CO) with TI Stellaris launchpad (operating voltage is 3.3V) but according to datasheet MQ7 requires Vh= 5v and Vl=1.4v. So, how to interface MQ gas sensors with 3.3v microcontroller????
Yes, many people can explain it. It is an RS-232 interface chip. Why do you ask?
What camera you want to interface? Cameras used in Robotic applications?
Hi all. I would like to as if pic18f6620 can be operated on 3.3V. I want to interface an mmc card which should run on 3.3V. The datasheet of pic186620 said its operating voltage is 2-5.5V. I just wanted to be sure. Thank you.
Guys, I'm using this motherboard Gigabyte GA-8SR533P, I want to interface the PCI slot into my FPGA, is the PCI 5V 32 bits or 3.3V 32 bits, or can accomodate them ? it's easier for me if it's 3.3V 32 bits since I can interface directly to EP2C8Q208 without 16-BIT 2.5-V TO 3.3-V/3.3-V TO 5-V LEVEL-SHIFTING TRANSCEIVER, How do I know it's 3.3
Cyclone FPGAs basically support 3V PCI without external transceivers. You'll most likely achieve better signal quality with external transceivers though. interface to 5V PCI requires at least level translating bus switches.
There are "tons" of ADCs better suited for FPGA interface than ICL7135, but it can be done. You'll need 5V to 3.3V level converters, and decoding the multiplexed BCD outputs. All accessible IO pins at NEXYS 2 are interfaced through the Hirose FX2 connector, I think.
hi friends I'm trying to interface glucometers with atmega16 on uart. but the problem is that one of my glucometer gives LVTTL interface logic(0 to 3.3v) and another one gives rs232 signal (-12V t0 +12v) and one more glucometer gives TTL o/p (0 to 5v). but the problem is that my controller is capable to read signal ranging from 0 to 3.3v. so how
Dear I would like to connected I/O from spartan2 (@3.3v) to I/O in Virtex6 (@2.5v). Wich component do you porpuse in order to tanslate 20 bidirectionnal signals. thank s in advance regards
Level shifting the MMC/SD interface to 3.3v is certainly required in physical hardware and maybe required in simulation as well. The MMC/SD interface is by no means 5v tolerant. BigDog
Hey everyone i know this question has been posted several times , i read all the other topics but i didn't get the right answer yet well i want to interface my micro sd with pic 18f2550 , i format it with FAT 16 and i used the code in the mmc help section here is my code : // MMC module connections sbit Mmc_Chip_Select at LAT
