Precision Data Converter Design Notes

hello:

  I'am using the ADS1158, on my board ,there are 3 ADS1158 for 48th channel; I have read the datasheet, in the fixed channel mode , how to confiugurat the MUXSCH register for channel select .for example: I want to select the second channel, the value of MUXSCH is 0x01, it's a right?

thanks a lot!

i have ads1672evm pdk....and  my mm0 motherboard is rev d......so dpo i need to disconnect the jumper j13a of motherboard.....my email id is vaishali.dhamecha@generalmeditech.com......pls reply as early as possible.....

Hai,

      I am  using TPS54610 for my project.I want to calculate the output capacitor and output ripple voltage of the IC and also May i know how to calculate the frequency divider network..

The TPS54610 is a DC/DC converter, you might try Switcher Pro or perhaps TINA to simulate/calculate your output capacitor/ripple and frequency response.

For the ADS1672EVM-PDK, J13A corresponds to the left side of J13 shown in the Users Guide - this jumper should be opened.

Yes - In fixed channel mode of the ADS1158, a MUXSCH value of 0x01 would switch to AIN1 - i.e. the second channel.

Hai,

I am using TPS54610 IC DC/DC converter in my project.May I know What is the formulae used for Calculting the IC Power Dissipation.I checked with switch pro soft pro tool. I need to calculate maually for understanding and analysis purpose.Can you help me in this regrad...

@ anonymous,

your "I am using TPS54610 IC DC/DC converter" query should be posted in the power forum.

@ anonymous,

Please post your "I have problem about ADS1247 read PT100" in the Precision Data Converter" forum.  

Hi~

My name is JAYDEN and FAE in Arrow korea

Our customer use DAC8718 part.

In unipolar mode, When input 0000h to USB/BTC code, DAC out voltage is 0.007V~0.011V.

We want DAC output voltage that fall below 0.005V. Do you have solution?

Also, In unipolar mode, Can we use dual power supply?

Please feedback to me.

hello,

i am using the ads1298 for my project .can anyone give default settings   on power up of ads1298

Bonjour les amis

Je suis étudiant en ingénierie électronique

je veux construire étape par étape un EEG avec ADS1299

il ya beaucoup de circuits dans google mais j'ai besoin d'un circuit très facile, seulement pour les étudiants

s'il vous plaît j'ai besoin de votre aide.
