Hi Takahashi-san,
I see your request for REF3025 data. I can look at what we have available, if we do not have it I have to look into doing a bench test. I have a question about your request.
1. Do you need REF3330 or REF3030? If this is REF3030…
Hi, Ryan:
Today we tested the SNR with REF3025 as the referece( the input : 1Khz Sin, 2.45V Peak to Peak, offest : 1.25V)
the SNR is sitll about 80dB, We also try to change the Mode, No any improvement. the result e as following, FYI
Regards …
Part Number: TMS320F280049 Other Parts Discussed in Thread: ADS7947 Tool/software: Code Composer Studio Dear colleagues
I used the ADC inside of F280049, I found one problem that the amplitude of signal would vary periodically.
So I do a test, To…
I made an audio AGC (Automatic Gain Control) circuit using the same part. Two ideas for you to explore based on what I found/did:
The input to the A2D should be though a 390 to 680 ohm resistor and a .001 to .01 uF cap. Work the RC so it is 10x your…
Hi Gerald,
First, It is not possible for me to select the INA849 in the "Analog Engineer Calc" app, as in your screenshot. I downloaded the the version with your link.
In the analog engineers' calculator, INA84 is listed in the drop down menu as shown…
Hi Max,
I think this looks OK. Some thoughts:
-This is a little bit mixed up between a schematic/layout. Just draw this as a schematic (functional only, don't worry about the actual pin positions in the IC) until you are happy with the functionality…
this just keeps getting worse...
I connected the new launch pad board that failed to do the firmware update back. I loaded the "out of the box experience" blinkLED into CCS and compiled it. It loaedd OK on that board, the program ran.
then I tried…
Thank you very much for your reply. I am at my wit's end...
1. I am not using any clock rate, because the digital lines are disconnected, and floating. I initially had the digital lines connected, but disconnected them while debugging to attempt to…
Hi Sandheep,
Do you have any recommendations on low-noise regulators for this application? My PCB has both 5V and 24V available.
If your 5Vdc and 24Vdc power sources are directly connected from wall wart adapter, you need to place some filters after…
Part Number: TMS320F28377D
Hi,
I am using the F28377D on a customised control board. I used the TI CLB tool to generate a PWM3 at pins GPIO4 and GPIO5 by using CLB overriding option signal using ePWM internal peripherals of PWM1 and PWM2. I have…
